No-CD/dead CPS3 motherboard questions

I've received a CPS3 motherboard that's supposedly dead, and that has a No-CD chip.

A few questions :
- is there a specific reason why a CPS3 mobo would die ? AFAIK there's only suicide batteries on the security carts...
- are there any known differences between a No-CD mobo and a standard one, besides the chip ?
- is it possible to change the game on a No-CD mobo ? By disabling the chip for instance ?
- if so, are all games compatible with it ?

That's all I can think of for now...

Thanks !

no cd mobo...mean that you don't need the cd...the game is preloaded on to the drive( check which game is preloaded..with the seller )...now the hard part is to find the working cart for the preloaded game

Yeah, you don't need the CD once the game is loaded into the SIMMs...

But the motherboard looks like a standard one, with the SCSI connector for plugging the CD-ROM drive even if you don't actually need it, and you must also plug in the security cart, which is the same as the "with-CD" version.

On a standard mobo, once the game is loaded, no data nor redbook audio (there is'nt any) is read from the CD, the game just checks if the CD is there, and I suppose the No-CD chip just bypasses this check.

Nobody, really ? I'll experiment a bit tonight.
