I have 3 PS2 (V1, 2 and 3) that don't boot PSX games with Origa V.2 (or clones like NovaChip) and just that, I mean, it boots everything else: PS2 CDs, DVDs, etc.
Does anyone had the same problem??
I think this is commom cause here in Brazil I've heard lot about it, but nobody knows the solution. They are using the GS code for PSX to boot.
