Forcing Mars III MA-502 to display import PS-1 games Full screen on 50004 PS-2
I recently installed a Mars II MA-502 chip in my EURO PAL 50004 GH-026 model. It works perfectly so far, but one thing that bugs me is that it will not display the import PS-1 games in full screen like the Matrix Infinity does.
Playing all those import PSX games, with that annoying black vertical border on the bottom part of the screen is very annoying indeed!
So, is there a way to force the Mars III MA-502 chip, to display the import PSX games in full screen, on my 50004 model?
Thanks in advance.
