Is the author of this emulator a poster on GP32x? I wanted to ask about the ETA til the Cave driver will be supported so 16 MHz 68000 games like Donpachi, Dodonpachi (ddonpach), Esp.Ra.De (esprade), Dangun Feveron (dfeveron), Guwange (guwange) et al might be supported. The CPU cores required to run them should be in place now, and with some decent overclocking they should all run well. They're major shooters in the Bullet-Hell shooter realm, and it would mean a ton to me were I Finally able to play them in a portable format!
Same goes for some other 68k shooters like Mars Matrix (Mmatrix), Giga Wing (gigawing), Strikers 1945 I/II/Plus (s1945, s1945ii, s1945p)! 
Also just a side note about Aero Fighters (aerofgt) which I added to the wiki, it expects rom files in the romset from a very old MAME Version, and a modern romset for say, 0.9x or up won't work. I had to dig around on the 'net to find a copy that worked, as it needed files that aren't present in newer distributions of that romset...
