    omp: Thank you for your help. I am pretty sure my soldering is good. I have checked them all and they are good. (Maybe i have to check it again) I am almost in the same boat as beharius. 1 works the other one doesnt.

    The reason Leg 44 of the chip is not wired to leg 7 of IC502 is because i use this:

    Side note this was much easier than that nightmare saturn bios.

    Leg 44 (WE) can also be connected to the pin B14 of the GDROM connector(CN503)...

    WE can also be connected to VCC (pin 23) - it just means you cant write to the chip

    The only incompatibility I've come across after modding 50+ DCs is a DC where the GD-ROM won't properly read discs anymore and I'm pretty sure it's a GD-ROM problem and not a BIOS issue.

    Oh no, please don't let me be the unlucky "winner" if I ever have to replace my DC. Already bad enough that similar happened when modding GC.

    I doubt it, I think the GD-ROM on this thing isn't seated 100% but I've been too lazy to bother trying to reseat it.
