can psio support games which need specialized bios?

Post by dcma » June 25th, 2018, 8:13 pm

My psio is ready to work, but some unoffical Chinesized games can't work well. These games need specialized bios to ensure normal display of fonts, they were perfectly supported by epsxe. Can psio support switching bios of ps console or can psio support these unoffical Chinesized games by other methods?

sorry,sir. My english is very poor, ill try my best to explain it.
In fact, it’s not a problem of psio. For example, in the "silent hill" (unofficial Chinese version), origin bios was modified by embedded Chinese font into it, the font in the modified bios will be used in game to ensure proper display of Chinese character. So this game works pretty well on emulators, such as epsxe or Retroarch which support booting from the modified BIOS. But it cannot be supported by PlayStation console unless we flash the modified BIOS for the console. Now my psio is here, without flashing bios of ps, is there a chance for running this game on psio , or the question is does psio support booting with modified BIOS?

Yes, PSIO will boot fine with a modified BIOS, but if it doesn't however for whatever reason (poor implementation of the original boot logic, etc), we won't return or replace your cartridge since it's not a cartridge fault.

thanks, of cause i will not ask for return or replacement.
One more thing, will you be able to add a function, to ensure that psio could boot from a modified BIOS in sd card, without flashing the BIOS of ps console?

Sorry, but that's not possible to do. PSIO only has access to certain CPU data and address lines and the BIOS uses quite a few of them directly which would still require soldering a new ROM.
