i am going to list my wiz on ebay it has a 16gb real pny card. but i wanted to give any one here 1st chance to put in an offer for it so i do not have to pay listing fees. USA shipping only
if you want some metal slug you can also try Metal Slug Advance gor gba seems to run full speed and is fun

Alien vs Predator(use to own cabnet) and Giga Wing(might be impossible to win) are two good cps 2 games mame seems to play both full speed
also the Fatal Fury series
why not port it your self? or you could just give dev time and be thankful for what has been done for free. the wiz still runs more then the dingoo
or just play shook tropers
I do not own a dingoo but I think if you install a Dingux it fixs "pressing of buttons at the same time"
I do have to say I love the wiz. its strong too I dropped it on a cement floor two times and it did not even scratch it
