I’ll be doing some benchmarking soon, will publish the results here. The only graphical differences I have found is that they seem to be rendered more quickly. I’d be interested to see how yours differs? Apart from the extra logo boot some that come to mind: Panekit, Kero Kero King, Ridge Racer, Pepsiman, will think of some more I saw good improvements in. I’m not sure about how PS1 on Vita works, but it’s definitely something that should be mine is the one you found in the wild. My dump has no white (Sony logo) boot screen but does have the black (PS logo) boot ah, I see. The game calls the BIOS (which is optimised) so the emulator or device running the game is almost irrelevant. I’ve only been testing on low power devices (POPS/PS2, SNESC, RPi3) so no Mednafen PSX but I’d expect the benefits to be seen there, too. What’s the BIOS hash (MD5, or CRC) btw? CRC32: 5660F34F So I am wondering, how has this enhanced BIOS been optimised and modified to improve performance? IDA Pro crashes when trying to open it as a PSX BIOS, so it must be quite different in some way? This tutorial aims to help you dump your PS2s BIOS image for use with the PCSX2 emulator (or whatever you need it for) using only your PS2 and a USB flash d. The enhanced BIOS seems to be based, at least in part, on the “final” PSone BIOS (v4.5) judging by the plain text it contains. Some games that refuse to run at all when using traditional BIOS run just fine using the enhanced BIOS. Other more demanding games can be run in hi-res mode when using RetroArch, whereas they could not using a traditional PSX BIOS. There are definite frame rate improvements, such as removal of stuttering in some games. So far I’ve tried the BIOS using the following emulators: It’s possible to extract the PSX BIOS using a hacked PSP running 6.60 CFW.Īnyway, I extracted this strange BIOS and… the claims are true! You can transfer those files over to a computer through an external drive or using a FTP connection between your PlayStation 3 and your computer. This sounded crazy to me, but I have an open mind, so I decided to check for myself. For dumping disc-based games, you need to use multiMAN homebrew software in order to dump your disc files. I recently read several mentions on various forums about the PSX BIOS that is included with PS1 on PSP game downloads allowing games to run more smoothly. This selection of PS1 games are playable on up to three platforms: PSP, PSVita and PS3 (which platforms exactly depends on the individual game release). As you know it’s possible to buy and download PS1 games from Sony’s PSN service.
