I have a Dreamcast
US version (Red logo) 110V
I believe it have a mod chip in it.
it can read backup game CDs but can't read original GD-ROM games.
How can I disable the modchip? or is it have a mode like the PS2 modchip?
like original game mode? backup mode? disable mode?
how can I identify what kind of mode chip is in it?
Thanks
