Thanks for the ROM collection! I wasn't able to unzip the CAEFLASH.zip file and CAETLA30..38.zip's. Either that 10 files are corrupt, or I was doing something wrong. Did anybody else have that problem, too? Or got them unzipped okay?

The PU-8 mainboards (SCPH-1000) have a 7pin power supply connector (unlike later boards with 5pin connectors). One of the extra pins is just another GND pin. The other one is +3.5V standby, ie. that pin is powered even when the console is switched off. What is THAT for? From what I can see (when gaz...

I have been doing some hardware tests on a PSone to find out how many sectors the console can hold in its sector buffer. The result is a bit puzzling: It seems to be able to hold up to EIGHT sectors, BUT: it allows to access only TWO of those sectors. The other sectors are lost - they appear to be i...

Hi, I've released a new playstation document. It's trying to give complete specs on cpu, gpu, gte, audio, cdrom, joypads, mice, lightguns, bios, and everything I could think of. http://nocash.emubase.de/psx-spx.htm - html version http://nocash.emubase.de/psx-spx.txt - text version I hope it'll be us...
