cu: pup is hard, ppc is hard....
amiga amp works best in wos mode, mame pup is the fastest we got and works fine under pup emu.
also i think i have found maybe...10-20 prods that aint wos pup emu ready (working) , but there is alot to take care of before you know for sure that it wont work..
about mame , that crashed here also in the start , dont know why..but i downloaded a new file from the mame site and now it works fine (with menu etc).
the best way to test pup emu is by running pup tools , but seriously i can't recomend much.
why i said wos is what u want to use anyway...

be sure you have enough free mem when you run mame + make sure you have unzip ppc version if you dont ...well it will crash or be very slow..
cheers
