Suppose you could swap out the existing set with something a bit larger. If the 32x port is capable of using the additional ram without a hack that would be interesting and quite useful. Honestly the fact I was able to get this to work was mostly luck in that all I needed was a hex editor and logic - I can't do 68k ASM to save my life. http://www.romhacking.net/hacks/619/ I'm assuming you mean this patch? It won't apply because it isn't the PAL rom. I'll see if I can get lucky a second time. EDIT http://www.mediafire.com/?e5d5dashbce508c 20 will load in Gens now. I haven't played through to be sure everything is accessible but from the readme it sounded like the map was modified to work with the engine rather than the other way around.
