So in the mame set I have..there is 3 or 4 different version's of Moonwalker. I currently use a X arcade tank stick on Hyperspin. I have no issues with input on any other game. For some odd reason the Bootleg version of Moonwalker will respond to buttons however the screen does not display properly so its kinda useless. It wont work in either Mame itself or going threw Hyperspin. There is around 20 or so files in the Bootleg Zip vs the United states version Zip which only has 3 files in it. Ive tried re downloading United states Zip to see if maybe mine got corrupt but it didnt help. Ive tried re mapping keys and nothing seems to matter. Any ideas? Thanks guys and gals.
