Squidgesnes 0.38 - Snes Emulator for the GP2X

Wanted to take a break from PicoDrive, so I took a look at SquidgeSNES code, because I do occasional SNES gaming. I don't like using scripts, so first I added performance options to the menus. I don't like scaled display, so I keep it off, but then there are problems with PAL games like Mario, they were just incorrectly centered, so I fixed that.

The strangest thing in the code was that the sprites were being drawn in wrong order (IMO), so I changed that. This seems to fix several games, but does it break anything? I want YOU to go and find out.

So now I'm going to try walking through the code and do some refactoring. Every time I make something noticeable I'm going to post an update. It is up to you to find as many bugs as possible. I want them to be constructive, not something like "BUG: second core is not used, go and make use of it". SNES is much more complex system and I am not familiar with the code and how it works, so I can't go directly to that. It might be not worth the effort to move code to second core at all. So please be patient, currently I am quite motivated to work on this.
