Re: How to dump your CDROM BIOS (Firmware)

It is possible to dump SCPH-102 CDROM BIOS? 102 models use different controller and that's why nobody dumped it?

Re: [DOWNLOAD] CD-ROM (HC05) Firmware Dumps

There are two different SCPH-1000 roms. The later one (which oddly has a lower reference number) has bug fixes.
What kind of bug fixes you mean here? How do you know they fixed something in firmware? Did you reverse engineered it?

PSOne development kit

It is possible to convert stock PSone to PSone dev-kit (yaroze). Flash memory (bios etc) from Yaroze, to PSone. One person from Polish scene did it (in 4 years). But he didn't want talk about it. So it is possible ?
