I figured out a way to use the snes emulator for ps2 hdadvance. I'm sure there is a easier way to do it(I'm trying to find it online) but this way requires you swap to a rom disk when snes is up and working on your hdadvance. 1.load up hdadvance (cdversion) and convert snes emulator using the fliptop. For those of you that don't have a flip top, you could open your ps2 system to install snes emulator, and then close it up again. 2.When you load up hdadvance you have to use the cd version. When you run snes emulator, the title screen comes up empty. Press the eject button and insert your snes emulator cd disk (you could make a separate disk with more roms to read) and it should read the roms. Basically what this does, is it only installs the snes emulator with no roms. So you just swap the disk with a rom folder full of all your rom needs. It beats the hell out of swapping with swapmagic because my playstation has problems reading it. This is also good if you have no fliptop(opening ps2 and installing)or no mod. I have gotten the genesis emulator working like this too. i believe you could also have one cd with your genesis and snes roms in there.
