Re: Official PSIO News and Development Thread

actually we know, how to improve firmware, on sw level. but it can be not enough, for example xa decoder is performed by ARM, so future improvement is to move decoder and other logic into fpga, so the mcu will act mostly like HC05. additionally, if there's unknown issues, we plan to analyze how orig...

Re: Supported SD Cards

further research could be pointed to use partitions, we're using only 1st one, AFAIK it possible to use 4, so it might be the way to extend capacity of storage device, but more partitions means more complicity of code support. bit need to test, might be on DCIO as it hasgot the access to IDE(SATA) HDD

Re: Vib Ribbon hardware fix ?

Originally when CD-ROM is playing the CDDA audio, it doesn't send it to the CPU, as it's non-data frames, but it sends as stream directly to the SPU, so the SPU is capable to catch this data into the memory, then CPU can read it, which is used as information for visualization as PSIO doesn't use suc...

Re: Rockman X3 Compatibility

it requesrs to use cdda tracks or cu2 file.
my suggestion to try cu2 file even if y have only 1st track.
it works for me from usb and cu2 file. but i don.t know you got from SD card, if fake cdda tracks would play without affects/noise..
but better to find version all-in-one image file

Re: Questions before buying

it's intersting idea, any suggestions about how it will work?
Do multi-bin games use some description file, like CUE where we culd get informaton about content, or use similar names and some kind of sign about track , like game_xx_.track01.bin , game_xx_.track02.bin, etc ?

Re: PSIO locking up and no longer booting

Additionally:
- we recomend format SD card before using
- if you un-pluged PSIO and it's still working with issue - it might be something from SW-board side. (preferable to see picture of how you've done the instalation/soldering)

Re: PU8 soldering failure - alternative?

could you show pics of how it looks like (mother board with mods).
hang on happens even without psio, if CD_CS doesn't reach actual pin of cd-dsp ic. so as result CD_INT doesn't reply. or issues w/ CD_INT.
as result PS1 sends commnds to cd-rom and have no replis from it.

Re: PSIO does not see all the games in the SD card

we would also recommend to format the SD card before use. (if you didn't do it, and just deleted all files).

Re: PSIO does not see all the games in the SD card

Do you see Menu is loading well?
You should place the game into a folder.
Menu checks through folders, and image should have extension like : ISO or BIN or IMG.
Try to use short name of the games's folder and the game image (like: "APE_ESCAPE.BIN").
