Welcome to the (semi)official RetroArch/Libretro cores thread for PS Vita ("I THINK I got the right subforum this time" Edition!) Small disclaimer: Make sure you are on Firmware 3.60 with the latest HENkaku exploit! It is recommended to ensure you are on the latest revision of HENkaku by navigating to henkaku.xyz via the Vita's Web Browser. FBA/MAME disclaimer: Final Burn Alpha uses a different ROMset from the NJEmu PSP emulators (Those use MAME 0.12x series ROMsets). MAKE SURE you are using the Final Burn Alpha v0.2.97.30 ROMsets with FBA. ONLY USE MAME/NJEmu ROMsets when the MAME emulator is confirmed working! For detailed explanations on RetroArch itself, please consult the Libretro wiki at http://wiki.libretro.com/index.php?title=Main_Page for non-Vita specific questions. If any bugs are present in any of the Libretro cores or exist within the RetroArch UI itself on the PS Vita, and are not acknowledged in the main post, please report them here. The goal of the article is to provide as much information on what works and doesn't work currently alike on the PS Vita port of RetroArch and the Libretro cores. For future note: Initial Quick menu combo is L1 + R1 + Select + Start, You can change this from Main Menu -> Settings -> Input -> Menu Toggle Gamepad Combo. (Thanks for the idea, user Shinigami Kiba!) Latest Nightly Builds: http://buildbot.libretro.com/nightly/playstation/vita/ Current Version: Febuary 13th Build, RetroArch version 1.4.1 Latest Stable Builds: RetroArch v1.4.1 (Click me to download now!) Changelog: 02/03/2017: Stable release build for PlayStation Vita has been released! Official Netplay support has been added! Use Main Menu -> Netplay to easily find and connect to local Vitas in a local network or over-the-air! Warning: Does NOT work cross-platform between Vita and any x86(_64)-based RetroArch distro! Current Available cores (package name/emulator name/emulated console): Current Performance: Thanks for the suggestion, Chesskid1! Reminder, these are estimations and are not to judge overall performance of each core or RetroArch as a whole. Notable exceptions to each rule will be noted. Consoles Atari 2600 (Stella): Fullspeed. Atari 7800 (ProSystem): Fullspeed. Genesis (Genesis Plus GX): ~60fps, consistent. Genesis (PicoDrive): ~60fps, same as Genesis Plus GX. Genesis 32X (PicoDrive): To be tested. NES (FCEUmm): 60fps, consistent (This IS the NES, after all... (^^;; ) NES (Nestopia): 55-60fps, inconsistent, recommended use FCEUmm. PC Engine (MednaFen): ~60fps on HuCard games, ~60fps on Super CD-ROM2 games. PlayStation (PCSX Re-ARMed): HEAVILY dependent on game, expect anywhere from 60fps in 2D-based games to 30fps in some 3D-based titles. SNES (Snes9x 2005): ~55fps - 60fps on standard games, ~50fps on SuperFX-powered games. SNES (Snes9x 2005+): To be tested, assumed ~50fps - 60fps on standard games. Frame drops compared to Regular '05 Snes9x are noticeable, however, on select games. SNES (Snes9x 2010): ~40fps on standard games, requires further testing; recommend using Snes9x 2005 instead. Sega Saturn (Yabause): Basically nonfunctional, Proof-of-Concept only. Vectrex: ~50fps, however this is fullspeed for Vectrex. Computer Systems MS-DOS (DOSBox): Functional, fairly slow, however; mapping instructions here. ZX81 (81): ? ZX Spectrum (Fuse): Full speed. Handhelds Atari Lynx (Handy): ~60fps Game Boy (Gambatte/TGBDual): ~60fps. Game Boy Advance (GPSP): ~45-50fps, generally above half-speed. Game Boy Advance (VBA Next): ~50-60fps, below full speed, but better performing than GPSP. Neo-Geo Pocket (Color) (MednaFen): ~60fps Virtual Boy (MednaFen): ~25fps-30fps. WonderSwan (Mednafen): 60fps on WonderSwan, ~30fps to 60fps for WonderSwan Color. Arcade Systems Final Burn Alpha: Varies by ROMset, generally better performance than MAME however. CPS1 (FinalBurnAlpha): 60fps, consistent. CPS2 (FinalBurnAlpha): 60fps, consistent. Neo-Geo (FinalBurnAlpha): 60fps, consistent. MAME (0.37b5): Varies by ROMset, generally full speed in most cases, possibly slower than FBA yet slightly more accurate(?). MAME (0.78): Varies by ROMset, generally half-speed, if not slower; recommend using FinalBurnAlpha instead. Engine Ports 2048 (The mobile phone game): Working. Cave Story (NXEngine): Fullspeed. DOOM (PrBoom): Fullspeed. However, using "Linear" filtering on anything but fog will drop framerates to half-speed. Quake (TyrQuake): With default pak0/pak1.pak, 40fps-50fps, adjustable in settings. Recommended use Rinnegatamante's VitaQuake instead. Current Bugs: Global Rewind/Fast Forward currently cause sporadic performance hitches on Genesis Plus GX (Requires further investigation). Individual Core installation may overwrite another random installed Libretro Core. Be weary of this, as it's a sign that the nightly set installed has added/removed a core. glui menu driver lacks font assets, currently unusable. Currently, using either the AiO Executable or the individual Core packages may exhibit random occurrences of loss of control over Libretro as a whole. The only known solution is to suspend/resume the application to restore control, however this will not work with any CD/Disc Image-based title as it will cause the game to inevitably freeze. (Is this still the case?) Older builds from August may not work with the xmb menu driver; if this is the case, delete your current retroarch.cfg and launch any RA core, and it will regenerate an updated default configuration file. Core Specific nxengine_libretro: Collecting Health Expansions halts the game (Application Crash). (Is this still the case?) genesis_plus_gx_libretro: SegaCD Redbook audio hangs when suspending/pausing the application. Attempting to load game assets in the same game afterwards soft-locks the game (Virtual CD is ejected?) Thanks for the report, wolven9! vecx_libretro: Sound pitch is an octave lower than original hardware? desmume_libretro: Cannot load Application (Vita System Error code "C1-2569-2") fuse_libretro: Cannot load more than one ROM in a single session (Application Crash). To change/reset a game, a complete reload of the core is necessary (As "Reset" restarts the virtual ZX Spectrum; NOT re-loading the game). Fixed Issues/Bugs Please note that these bugs are currently a non-issue or fixed as of the latest Stable/Nightly builds. These remain purely for historical purposes and are not indicative of current RetroArch/Libretro progress. Bios Files Required (Place in ux0:data/retroarch/system): DOOM (PrBoom): prboom.wad (PrBoom system file, place in same directory as DOOM .WADs) (Can be obtained here). Sega Genesis/Mega Drive (Genesis Plus GX/PicoDrive[?]): Sega CD (bios_CD_E.bin, bios_CD_J.bin, bios_CD_U.bin). NES/Famicom (FCEUmm): DISKSYS.ROM (Famicom Disk System BIOS only). Neo-Geo (FBA): neogeo.zip (SNK Neo-Geo BIOS, must contain UniBIOS as well, place in same directory as ROMsets). PC-Engine (MednaFen): syscard3.pce (TG16 CD-ROM System Card ver. 3.00). PlayStation (PCSX ReARMed): SCPH550X.BIN (PlayStation BIOS). "X" stands for 0, 1, or 2, depending on region Game Boy Advance (Required for gpSP only): gba_bios.bin (Game Boy Advance BIOS). Extras: Warning: The following does NOT apply to the recently introduced RetroArch All-in-One Executable. This, however, will remain for as long as the individual core packages are bundled in current nightlies. Thanks to users sj33 and Melon Head, a set of customized unofficial icons are available for each individual RetroArch/Libretro core. This will make identification of the individual cores easier and the presentation marginally improved. A download is available here. WARNING: Nightlies are posted daily, if not hourly, and thus the correct RetroArch core folder names are not guaranteed to remain the same across Nightly Builds. Take caution in replacing files, as when applied to the wrong Nightly, are prone to creating mismatching icon/name bubbles. sj33 will be sure to update the folder structure as new cores are developed and added. Directions: Extract/transfer the containing "RETR000XX" folders to "ur0:appmeta/" and overwrite when requested. NOTE: uR0: and uX0: are different partitions entirely, as ur0: maintains active meta/image data for installed applications. If you'd like to extract specific icons for specific cores, you may check for correct core folder by examining the containing "sce_sys/param.sfo" file and locating the string "RetroArch xxxxx" amongst the corrupted text [xxxxx being the core name as displayed in LiveArea].) Reboot the system to view the changes made. Thread is WIP. If you have any concerns, leave a post or message me. Credit where credit's due to all the users who have assisted with RetroArch/Libretro, the Vita ports, and everyone who provides unofficial fixes, advice, and assets for use with Vita RetroArch/Libretro. Thank you!
