In this doc, the first memory card slot will be referred to as 'Memcard slot 0' and the second slot will be referred to as 'Memcard slot 1'. The software renderer is locked to 16bpp while the Vulkan renderer will automatically set render at 16bpp if dithering is enabled and 32bpp if dithering is disabled. The upper image demonstrates the current behavior on Beetle PSX HW while the lower image is the same title running on Mednafen 1.22.2 with expected behavior. Progressive timings are 59.826 for NTSC content and 49.761 for PAL content, and interlaced timings are 59.940 for NTSC content and 50.000 for PAL content. CPU Frequency Scaling (Overclock) [beetle_psx_hw_cpu_freq_scale] (50% to 750% in increments of 10%. Tekken 3. Here is the first release of Mednafen/Beetle PSX HW. '1x(native)' emulates original hardware but can look grainy at higher internal resolutions. All multiples of 128 (default) should be fine. Note: This can have unintended consequences. This can improve in-game loading times and eliminate stutters due to emulated CD access, but may cause issues on systems with low memory. All .pbp games will have to be added to playlists manually. When enabled, monitors the max values reached by the input, using it as a calibration heuristic which then scales the analog coordinates sent to the emulator accordingly. Xbox gamepads typically require a deadzone of 15-20%. 'memory only' is recommended for best compatibility. Close. NegCon Twist Deadzone [beetle_psx_hw_negcon_deadzone] (0%/5%/10%/15%/20%/25%/30%). Lei-lei did this reversal of the PowerVR effects with his PowerVR PCX2 card (which has the same exact post-dithering as the newer PVR GPUs) and observing lossless official press release screenshots and xjas’s VGA capture dump. MDEC YUV filtering. Max cycles run by CPU before a GPU or DMA Update is checked, higher number will be faster, has much less impact on beetle interpreter than dynarec. * Overscan cropping available via Core Options instead of frontend settings, The Beetle PSX HW core's library name is 'Beetle PSX HW'. Replace Textures [beetle_psx_hw_replace_textures] (disabled/enabled). share. This can lead to audio and video desynchronization, among other issues. To run games, you need to extract a PS1 bios (DOWNLOAD) in the system folder of the RetroArch directory. Additional Cropping [beetle_psx_hw_image_crop] (disabled/1px/2px/3px/4px/5px/6px/7px/8px). Log In Sign Up. With GNU Lightning, there are no such issues. Software Framebuffer: On. To learn more about some of the recent developments surrounding 4DO, be sure to read our dedicated article on this. May be used to correct alignment issues. motion blur, FF7 battle swirl, etc.) Some important updates for Beetle PSX too – Lightning/Lightrec (the new dynarec technology being used) has seen many updates and improvements. Enable Memory Card 1 (Restart) [beetle_psx_hw_enable_memcard1] (enabled/disabled). This reduces macroblocking artefacts (squares/jagged edges) as shown below: Track Textures [beetle_psx_hw_track_textures] (disabled/enabled). If disabled, certain operations are omitted or rendered on the GPU, which can improve performance but may cause graphical errors or cause stuttering. 'cubic': Analog stick displacement is mapped cubically to negCon rotation angle. Turn it off if you care about getting the best performance possible. Make sure you have the textures extracted already in your [ganename]texture-replacements dir, and make sure that the dir is in the same dir that your game content file (ISO or other image format) comes from. We’ve added a couple of video output postprocessing options. 8-9% performance improvement, Ensure reset_drawing() is called whenever geometry changes (prevents out of bounds video buffer access), Add support for disk control interface v1 (disk display labels), Remove savestate_initsave + better VKBD mouse control, Fix from WinUAE 4.1.0 for Chaos Engine 2 AGA crash, Audio via retro_audio_batch_cb + MDS fix + pregap fix, Updated to latest version (0.218) – will be available later today [tcamargo], Fix window resize for VDP1 layer – Fix Winter Heat in resize, When OREG is read while status flag is clear, force command processing – avoid race – fix Rayman controls, On intback continue write, status flag shall be 1 – Fix batman boot, Set the vdp1On when updating using write – Fix Sega Ages loading screen, If the VDP1 is cleared with a non transparent color, assume it shall, Introduce the development RAM Card used by Heart of Darkness, Display VDP1 layer cleared with non transparent color, Fix two consecutive end code on core OpenGL – Fix Code R, fh is related to kx – shall fix some bad behavior on RBG CS, Update vrc2and4.c – support for big bank CHR (Contra 3) matched by hash, 134 – replaced Mapper134_init with Bs5652_Init, Fix savestates – prevent possible issue on big-endian by adding mask, Fix savestates – specify correct variable size to state struct, Backport new FDS [Famicom Disk System] disk handling – fixes saving issue with some games (Bubble Bobble, Super Lode Runner II, …), Allow access to Sega CD’s extra memory using retro_memory_map [negativeExponent], Add input analog axis range modifier [stouken], Should finally compile now for Raspberry Pi 4, Implementation of new Disk Control interface (including custom labels), px68k switch menu now accessable as core options. Texture Filtering [beetle_psx_hw_filter] (nearest/SABR/xBR/bilinear/3-point/JINC2). It used motion sensing technology to detect swings you would make with the sword. Gun Cursor [beetle_psx_hw_gun_cursor] (cross/dot/off). Enable smoothing of 2D artwork and UI elements without blurring 3D rendered objects. This has been an issue in the HW renderer for as far back as I can tell, and isn't handled correctly without the … PSX Driving Racing. Examples include Doom/Hexen, and the water effects in Soul Blade. Changed name from dhewm3 to boom3 at request of author, Libco removed. Setting DMA Cycles to 1024 can have a big impact on maximum framerate. A linear response is not recommended when using standard gamepad devices. PAL copy protected games need a SBI Subchannel file next to the bin/cue files in order to get past the copy protection. Start Beetle PSX HW, make sure that you are using the Vulkan renderer (it won’t work with either the software renderer or GL renderer), and then make sure the ‘Replace Textures’ option is enabled. Internal GPU resolution: 16x. So far we have let it cook slowly in the oven. Alternatively, there is a desktop mode for RetroArch which is more PC-like. 'linear': Analog stick displacement is mapped linearly to negCon rotation angle. Flyinghead has been busy improving arcade emulation support. Resident Evil 3 - Nemesis. Settings with (Restart) means that core has to be shut down for the new setting to be applied on next launch. Advantages: The core worked fine, I updated it, and It stopped working. PlayStation BIOS files (NA/EU/JP) for Mednafen by Sony. After figuring out how to set the system directory by manually altering the retroarch.cfg file, I saved the three required BIOS (JP, US, EU) onto ~/.config/retroarch/BIOS which is the location I created for them. Libretro Docs - Sony - PlayStation (Beetle PSX HW) This is RetroArch's document page, modification or development information outside of this repo may be incorrect. I really don't think anything changed on my end. a – If you have already installed the core before, you can go to Online Updater and select ‘Update Installed Cores’. Default: 0). This game is actually fairly unique in that not only was it a custom Naomi hardware design by Namco (more capable GPUs that could operate in an array), but it also had an unique input device. (Plus Dosbox Pure out for Android/Mac/Windows). Much faster than interpreter, but CPU timing is less accurate, and may have bugs. The libretro (.srm) and Mednafen (.mcr) formats are internally identical when used with Beetle PSX. Dump Textures [beetle_psx_hw_dump_textures] (disabled/enabled). When 'Crop Horizontal Overscan' is enabled, this option further reduces the width of the cropped image by the specified number of pixels. When this option is enabled, the DualShock input device can be toggled between Digital Mode (analog sticks off) and Analog Mode (analog sticks on) much like real hardware by pressing and holding START+SELECT+L1+L2+R1+R2 for one second in lieu of a dedicated Analog Button. The Beetle PSX HW core supports the following device type(s) in the controls menu, bolded device types are the default for the specified user(s): Rumble only works in the Beetle PSX HW core when. Dynamically recompile CPU instructions to native instructions. MDEC YUV Chroma Filter [beetle_psx_hw_mdec_yuv] (disabled/enabled). Default: 0). Tested with Skies of Arcadia and D2, (PVR) Better saturate colors when converting tex to higher precision. On Android, ePSXE does have some features that are … Display Internal FPS [beetle_psx_hw_display_internal_fps] (disabled/enabled). GTE Overclock [beetle_psx_hw_gte_overclock] (disabled/enabled). When statically linking this in, the core could become as big as 80MB non-stripped and 60MB stripped. Will not work with either OpenGL or software rendering. This is an upcoming feature that will be available soon –. Hardware is less accurate but may have improved performance over the software renderer at internal GPU resolutions of 2x and above on capable hardware. For instance – bringing up the auto-map in Doom 64, or the first menu screen transitions in F-Zero X, or firing your gun for the first time in Quake 64 – all of these would add temporary 1 second or more stalls the first time a code block was being compiled. Last Scanline - PAL [beetle_psx_hw_last_scanline_pal] (230 to 287 in increments of 1. Below we detail the most significant changes to all the Libretro cores we and/or upstream partners maintain. Thanks! Beetle PSX seems to be a lesser known emulator core, and many people still steer towards ePSXe. If it causes no issues in a game, this should give you a not-insignificant performance boost in some games. Right now, you are forced to move the image to your SSD as well, because otherwise it just dumps and/or reads these texture replacement files from the same dir as the image, in this case the mechanical harddrive. However, we hope that by putting it out there already, the community can already start experimenting with the option, putting it through its paces, and see what its limitations are and how far it can be pushed. The three BIOS files needed by Mednafen (and RetroArch/OpenEmu, if using Mednafen as core). negCon compatible titles provide in-game options for setting a 'twist' deadzone value. For proper PAL game compatibility, the 'Skip BIOS' core option needs to be set to off. It will attempt to use all HD textures from the ‘texture-replacements’ directory. Fixes Hydro Thunder – Time records music bug, (GL/Vulkan) Ignore trilinear filtering if texture isn’t mipmapped. Improves the quality of FMV playblack by smoothing the chroma channel when converting YcBcR to RGB. If using .m3u files, disks can be swapped by selecting Eject Disk, changing the Current Disk Index to your desired disk, and finally selecting Insert Disk. Selects the last displayed scanline when running PAL content. Enabling 'Crop Horizontal Overscan' will remove this potentially glitchy horizontal overscan region. If foo is a multiple-disk game, you should have .cue files for each one, e.g. A summary of the licenses behind RetroArch and its cores can be found here. Models: scph5500 - 3.0 NTSC-J (1996-09-09) scph5501 - 3.0 NTSC-U/C (1996-11-18) … Most (all?) Libretro is all about enabling people the power and freedom to do what they want with their legally bought content, after all. Second is Mazan – Flash of The Blade. When I load either the HW or non-HW Core, if I go to Information > Core it shows that the three … Options are listed below in the following format: Option Name [option_key] (setting1/setting2/...). Analog Self-Calibration [beetle_psx_hw_analog_calibration] (disabled/enabled). Setting a value less than 239 will reduce the height of output images by cropping pixels from the bottommost edge. Reported values may be inaccurate. If the core is unable to do so, it will fall back to the software renderer at 1x internal resolution. 3. When running such games with an Internal GPU Resolution higher than native, these triangles no longer resolve as a line, causing gaps to appear in the output image. Beetle PSX HW is a port/fork of Mednafen's PSX module to the libretro API. Mudo. Enables overclocking of the 2D rasterizer contained within the emulated PSX's GPU. To be exact, it’s an internal 24->16-bit buffer post-dithering pipeline stage. Gun Input Mode [beetle_psx_hw_gun_input_mode] (lightgun/touchscreen). Copy link DukeJP commented Aug 13, 2018. Manually editing core configuration files is typically unnecessary unless your frontend does not have a method for toggling options. Beetle PSX HW refuses to boot games … * Set Dynarec DMA/GPU Event Cycles to a higher value than the default 128 if you can get away with it. Description: Bandai WonderSwan/WonderSwan Color emulator core, Description: SNK Neo Geo CD emulator core. New comments cannot be posted and votes cannot be cast. Improves the appearance of 3D objects. Allows for perspective correct texturing when PGXP Operation Mode is also enabled. Most conversion tools will want a single .bin file for each disk. Maximum accuracy is still uncompromisable; anything that affects accuracy is optional and off by default. So this has been a project that has been cooking in the oven for about a year in the form of a bounty. Reduce multiplier value if experiencing loading issues, freezes, etc. CPU Dynarec [beetle_psx_hw_cpu_dynarec] (disabled/execute/execute_once/run_interpreter). Fixes Sturmwind menu, (GL4) Don’t use extra depth scale in fog calculation. OpenEmu on the mac is brilliant — you can quite comfortably play Playstation 1 games once you have it set up. Parallel RSP has been completely rewritten to use GNU Lighting instead of LLVM. Faster ROM loading 3. If you find certain graphics artefacts all of a sudden that were previously not there, you might have to turn this setting back on to get rid of the glitches. First and foremost consider this: This is a DEVELOPER oriented channel dedicated to report bugs and suggest features about the libretro core, please do not … In terms of game emulation compatibility, the Beetle PSX core is much better in that regard. RetroArch: Android, Linux and Windows are all supported targets. Forces content to be rendered with an aspect ratio of 16:9. Enables/Disables multitap functionality on port 1. Testing results. Internal Color Depth: 32bpp (so cool!) We are listing changes that have happened since then. If a game starts crashing or no longer boots from the BIOS screen, then you know you set it too high. The 2D character sprites and the portrait image on Beetle PSX HW are unnaturally squat. Setting a value less than 287 will reduce the height of output images by cropping pixels from the bottommost edge. PS1 Emulator (Playstation) The best emulator is RetroArch ( and then use the Playstation emulation core, Beetle PSX HW (mednafen_psx_hw_libretro). By default, the Beetle PSX HW core will use Libretro's savedata format for Memcard slot 0 and Mednafen's savedata format for Memcard slot 1. It gives the screen a green hue and adds a ton of feedback instead of it being a clean dithered 16bpp image. FCEU "mappers modified" is an unofficial build of FCEU Ultra by CaH4e3, which supports a lot of new mappers including some obscure mappers such as one for unlicensed NES ROM's. Yes, that’s right, a motion sensing sword is your primary input device in this game. The 'Aggressive' option will likely introduce visual glitches due to false positives, but is needed for correct rendering of some 'difficult' titles (e.g. Initial Scanline - NTSC [beetle_psx_hw_initial_scanline] (0 to 40 in increments of 1. Memory card behavior can be controlled with the following core options (Memcard 0 method, Enable memory card 1, Shared memcards). @rz5 I did try the dynarec, still 40 fps. GPU Rasterizer Overclock [beetle_psx_hw_gpu_overclock] (1x(native)/2x/4x/8x/16x/32x). Leave off for most games. For game savedata storage, the PSX console used memory cards. The '16bpp(native)' setting emulates the original 16bpp color depth. News. Disadvantages: Crop Horizontal Overscan [beetle_psx_hw_crop_overscan] (enabled/disabled). How is it different from beetle psx? Memory Card 0 Method (Restart) [beetle_psx_hw_use_mednafen_memcard0_method] (libretro/mednafen). While the game is running, it will dump all current active textures it comes across to a directory. You can always go for a lower value and see if that works better, while you don’t lose too much performance in the process. 26661 downs / Rating 72%. Member. Libretro Core Updates – New version of Mr. Boom, Coming soon – RetroArch for OpenDingux release (GCW Zero/RG 350/etc), RetroArch, Libretro core license violations by Hyperkin’s Retron5. Allows accurate emulation of framebuffer readback effects (e.g. Right now this is a problem for instance when you have your content stored on a slow disk device like a HDD but you want your texture replacement files to be read from your much faster but smaller SSD instead. This option is less necessary and can be disabled if the Internal Color Depth option is set to '32bpp'. Some performance tips for people that want to get the most out of their device: Aarch64 compatibility should be a lot better now. Also comparing it to how it looks in PCSXR. The joypad device being used has rumble support. Content that can be loaded by the Beetle PSX HW core have the following file extensions: RetroArch database(s) that are associated with the Beetle PSX HW core: Frontend-level settings or features that the Beetle PSX HW core respects. Replaces textures with files given in the folder -texture-replacements/ with the same name as dumped textures. Press question mark to learn the rest of the keyboard shortcuts. Due to the threaded model of emulation used in Mednafen, and limitations of SDL, a joystick is preferred over a keyboard to play games, as the joystick will have slightly less latency, although the latency differences may not be perceptible to most people. Core Aspect Ratio [beetle_psx_hw_aspect_ratio] (corrected/uncorrected/4:3). The Beetle PSX HW core has been authored by. A linear response is only appropriate when using racing wheel peripherals. The usual. Improved framerate 2. Alternatively to using cue sheets with .bin/.iso files, you can convert your games to .pbp (Playstation Portable update file) or .chd (MAME Compressed Hunks of Data) to reduce file sizes and neaten up your game folder. There was also noticeable VGA signal loss included in the VGA output when connecting your Dreamcast to a monitor with a VGA cable. To take advantage of Beetle PSW HW's Disk Control feature for disk swapping, an index file (a m3u file) should be made. Crash Bandicoot 3 - Warped . See the Saves section above for an explanation regarding the libretro and mednafen formats. Sets the deadzone of the RetroPad left analog stick when simulating the 'twist' action of emulated neGcon Controllers. Improvements include: 1. The ability to force specific renderers may not be available on all platforms. Use the software renderer for the time being. Keep in mind that save states also include the state of the memory card; carelessly loading an old save state will OVEWRITE the memory card, potentially resulting in lost saved games. HLE emulation of some special chips is optionally restored (defaults to LLE), to improve performanc… Last Scanline - NTSC [beetle_psx_hw_last_scanline] (210 to 239 in increments of 1. Browse All PSX Roms. So, to address the previous limitations of the dynarec – the two big ones were that runahead did not work, and that PGXP did not work with the dynarec enabled. Required or optional firmware files go in the frontend's system directory. Fixes Shenmue snowflakes color, (GL/GL4) PowerVR2 post-processing filter from leilei, (GL4) Fix blending issue when autosort=0. However, there are plans to make PGXP part of the dynarec as well, which could take care of this issue. When enabled, skips the PSX BIOS animation normally displayed with starting content. Not all games will benefit from enabling this setting as shown in the examples below. Mainly for PSX. This option has no effect when CPU Dynarec is not enabled. Line-to-Quad Hack [beetle_psx_hw_line_render] (default/aggressive/disabled). May be used to counteract letterboxing built in to some games. PBP and CHD file format support, developed by Zapeth; Software renderer internal resolution upscaling, implemented by simias; An OpenGL 3.3 renderer, developed by simias; A Vulkan renderer, developed by TinyTiger; PGXP perspective correct texturing and subpixel precision, developed by iCatButler; The Beetle PSX HW core's core provided FPS is 59.826 for NTSC games and 49.761 for PAL games (non-interlaced rates) and is toggleable to 59.940 for NTSC games and 50.000 for PAL games (interlaced rates) through core options, The Beetle PSX HW core's core provided sample rate is 44100 Hz, The Beetle PSX HW core's base width is 320, The Beetle PSX HW core's base height is 240, The Beetle PSX HW core's max width is 700 when the 'Internal GPU resolution' is set to 1x. Oct 25, 2017 4,021 Tennessee. This is particularly important when 'NegCon Twist Response' is set to 'quadratic' or 'cubic'. Initial Scanline - PAL [beetle_psx_hw_initial_scanline_pal] (0 to 40 in increments of 1. This causes significant position-dependent distortion and/or blending of textures such as warped lines across floors and walls. The hardware renderers have known issues -- check the compatibility section below or the core's issue tracker for more details. The Libretro (.srm) savedata format, when used with Beetle PSX, is internally identical to the Mednafen PSX (.mcr) savedata format, and can be converted between one another via renaming. Selecting '32 bpp' increases the color depth such that smoother gradients can be achieved without dithering, allowing for a cleaner undithered output. Like the PBP files, content must be added to playlists manually. hardware_gl and hardware_vk allow the core to ignore the frontend preferred hardware context and attempt to force a specific hardware renderer. The hardware renderers also allow various graphical enhancements such as higher color depth, texture filtering, and PGXP. New Vulkan graphics enhancements features in Beetle PSX HW! Choosing hardware will automatically select either the Vulkan or OpenGL renderer depending on the current libretro frontend video driver. RetroArch Android – New versions for Play Store – please read! Beetle PSX HW is a port/fork of Mednafen's PSX module to the libretro API. Netlink support is being worked on for Gun Survivor 2 Biohazard Code: Veronica. By default, the filenames of the Memcard savedata will match the loaded cue or m3u or pbp filename, like this: Loaded content: Breath of Fire III (USA).cue, Memcard slot 0: Breath of Fire III (USA).srm, Memcard slot 1: Breath of Fire III (USA).1.mcr, Loaded content: Final Fantasy VII (USA).m3u, Memcard slot 0: Final Fantasy VII (USA).srm, Memcard slot 1: Final Fantasy VII (USA).1.mcr. Software Framebuffer [beetle_psx_hw_renderer_software_fb] (enabled/disabled). What is Beetle PSX HW? Allows games to be displayed at native (low) resolution but with clean anti-aliased 3D objects. Dumps textures when they are accessed. User account menu. Using other API's such as OpenGL works just fine. In most cases, the 'quadratic' option should be selected. 3. While modern analog sticks have circular logical ranges, older analog sticks such as those on the DualShock have logical ranges closer to squares and can report larger values at the intercardinal directions than modern analog sticks can. If it works properly, you’ll start seeing low-resolution textures replaced by higher-resolution ones. 'Bilinear' and '3-Point' are smoothing filters, which reduce pixelation via blurring. You can even use something like Steam ROM Manager to manage the Steam shortcuts. 9612 downs / No votes yet. It is a Work-In-Progress. Beetle PSX currently runs on Linux, OSX and Windows. Mednafen 1.26.1 November 10, … The "4:3" setting should not be used and is only provided as a legacy feature for users desiring old incorrect behavior from the core. This speedhack can greatly reduce loading times at speeds higher than native but is known to introduce texture corruption errors, timing glitches, or loading screen softlocks in many titles. Produces best results when applied to titles that mix 2D and 3D elements such as 3D characters on pre-rendered backgrounds. For multi-disc content, make an .m3u file that lists all the .chd files instead of .cue files. Specifies the analog response when using a RetroPad left analog stick to simulate the 'twist' action of emulated neGcon Controllers. Supersampling (Downsample to Native Resolution) [beetle_psx_hw_super_sampling] (disabled/enabled). Install Beetle PSX (HW) First, head to the Main Menu, then select Online Updater. Port 2: Multitap Enable [beetle_psx_hw_enable_multitap_port2] (disabled/enabled). Allows for better object alignment and may reduce visible seams, but false positives when querying the cache produces graphical glitches in most games.
