Re: Compiling RUNIX (PSXLinux)

i believe this is as far as the runix guys got because you cannot mount a 128kb EXT2 partition if you were planning to use the memory card for anything.. I dont know what FS they used but they have code inside the runix sources for multicard support, and they say they planned on CF card support (or...

Re: Provenance emulator

Hi welcome Frank, https://github.com/Provenance-Emu/Provenance/wiki/BIOS-Requirements#sony-playstation this page seems to indicate that you need to "import" these 3 bioses just like roms. You should be able to find the right bioses right here: http://www.psxdev.net/forum/viewtopic.php?t=56...

Re: PSIO alternative ?

Arduino isnt powerfull enough, RaspberryPi probably neither. especialy the IO output. Maybe if you take the ALTERA Cyclone 3 FPGA and add it to your RaspberryPi you might be able to put out the right IO with speed and accuracy. but basicly youll be reworking the PSIO and the price ;) Raspberry can d...

Re: PS1 Memory Card does not format or detect (Genuine)

You could desolder the actualy flashchip if all else fails and use a eeprom reading to look at the bytes, recover whats lost. but thats only usefull for if you want to recover something, if memcardduino doesnt see it, or fails like your ps2, sounds like either the controll or flashchip is broken.
