hey TotheX,
Are you using an RGB cable?
Then check
www.megagames.com/dc for PAL/NTSC Detection patches maybe that is the issue with your games......
im just thinking of any game that is easy to made selfbootable.....
and then will run 1000% if it is made correctly.....
Try Mr Driller (bout 10mb) with the echelon SB tutorial.
Remember to patch all .bin files :-) ....
