PSX-XBOO.ROM bios support

Postby assemblyx69 » Fri Jul 19, 2019 4:04 pm

Hi Mr. schtruck please support the bios clone of no$psx v2.0 by nocash, it's freeware you can readily upload it in your pc through the utility function of the emulator. There are some successful attempts of using it in a real hardware from the assemblergames forum. Nocash said it should work in all emulators but if the emulator you're using requires you to put 512.00k bios file, you need to edit his bios clone by copying the lower
and upper half of the file using hex editor (black screen in fpse). According to him it's written entirely in ASM. The size of the bios is 256.00k so it's not compatible to fpse. Advantages of this bios, it's freeware you don't need to dump bios anymore from a real psx hardware, minimalistic gui (for me the official sony memory card manager gui is quite obnoxious), faster memory card access, built-in vcd player, etc.

Bug reports is also helpful to him you could send it through his email account from his official site or message him in nesdev forum.

Yes, it's inside his emulator this is how you can get the bios clone of nocash.

Download the emulator from his main site, I don't know if I can post the link here anyway here https://problemkaputt.de/psx.htm (you can check the legitimacy of the link from gametechwiki No$ page)

You should download the debug version (720 Kbytes) not the gamer version because he cut the debugging feature there.

Open no$psx v2.0 - Utility tab - Remote Access - Create nocash bios rom as raw image (PSX-XBOO.ROM)

Then it will produce the psx-xboo.rom bios inside the folder where the no$psx emulator resides.

I want to upload the psx-xboo.rom bios (256.00k) here but I can't attach the file.

So I upload it via datafilehost here https://www.datafilehost.com/d/56d2cb4d

edit: put the attachment to datafilehost

I sent the bios rom to your gmail.

Sir @schtruck if you successfully implemented it please put it in the changelog of any fpse version you first implemented it.

Yes, many emulators doesn't support this but it works in a real psx hardware using some cheating device to install the bios.

You can check this too, http://www.psxdev.net/forum/viewtopic.php?t=1319

The bios settings are stored in one of the unused memory card sectors.

There's one now that can emulate it and I only see it now because it's kinda new, Oct 28, 2020. Posted by HeyItsLollie to stenzek's github page (the one who made the duckstation). There's some screenshots also.

https://github.com/stenzek/duckstation/issues/1012

So duckstation can emulate it now.

Here's the android version, free.

Here's the screenshots from pc version of duckstation.
