Config wise, I don't think we need to do anything. The only thing we need is RomType = 1. Right now the priority is to get something booting.I will test this in a bit. But I wanted to ask if you think any other config settings might be useful?
Have you had a look through them? There are a lot of ones that define image size, effects on or off, and then there are ones that are game specific looking at certain regions of games code. Obviously the latter is not of use to us here, but the 1/0 options might be worth testing?
