I installed this a while ago, and happened upon this review afterwards.
I am a keen retro gamer, mainly setting up xmame and mythTV for the ultimate all in one home entertainment (I grew up in an arcade!!).
I tried the following roms obtained from the abandon/legalware site c64.com [i.e. a LEGIT source of roms]
These were also cassettes that I have in storage - unfortunately for my poor misguided youth this may be an offsite storage facility called a landfill...
Mad Doctor
Beer Belly Berts Brew Biz
Little Computer People
The Young Ones
New York City
Kane
Action Biker
Unfortunately, Mad Doctor wouldn't load, nor Little Computer People, I'll try other rom sources or be more patient...
The others played very well, on my ipaq 400mhz, with its raised controller. Somewhat worse on my 624mhz axim, because the controller is set in, which makes it fiddly.
I recommend you try all the above games.
I also use PokeSnes, which rocks, and megaman1-4&J are far harder than anything else known to mankind.
Mame install on PocketPC is next, anyone with experience? Just need some time!
