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. Broken Working The reason Leg 44 of the chip is not wired to leg 7 of IC502 is because i use this: http://www.mmmonkey.co.uk/sega-dreamcast-region-free-bios/#ic502 Side note this was much easier than that nightmare saturn bios.
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.
