Re: Wondering about CD drive data
theoretycally we can make signal similar mod-chip does... making image of game from 2x cd-drive to psio (SD/HDD) TAKES much time... maybe if y plug cd-dvd drive and sd/hdd in the same time you can do it faster.. but need to use notebook drives better. cause using 5.25 drives need 12v additinaly .

Re: PSone BIOS modding project
better keep them up. kernel code init system and HW in correct way and setup default exeption handling mechanism.
i,m not sure - but with changing code of the orig bios we can hurt check sum. and AR-like method is better way for update logo/intro/managers.

Re: PSone BIOS modding project
if you know where is this location in ram, it can be calculated to bios . as i said bios code copy shell data to ram from bfc18000 -> 80030000 x - address you got (in ram) y - address you need (in bios) ofs = x - 0x30000 y = 0x18000 + ofs or just : y = x - 0x18000 this is what you need, isn't it?

Re: PSone BIOS modding project
the code in the bios calls SHELL and it loading and execiting at point ExecuteShell();
so shell code is located in bfc18000 in bios and then copy to ram 0x8003000.
in some sites i saw grabbed shell as ps-wxw file.
