I have a Mortal Kombat(midway Y unit hardware) can I do a Eprom Swap to make it a Smash TV Boardset? or use one of the others in the same Y unit hardware.

Same question goes for turning a MK2 into a NBA JAM TE
Or is there a security chip I need to worry about.

Figured it would be a easy way to play both game but only keep 1 board.
or see it I could make a Multi game add on board with all the games programmed into a daughter card.

I'm gonna be honest I always wondered if you could swap out roms with games that use the same hardware. I'm thinking yes for some hardware but no for others. I know cps1 games have a security chip. Midway.... Anybody know or try it?
 
You may need PROMs off the other board or copies of them. Not sure how different they are...

Also, there are a shitload of jumpers on the board and you'll have to make sure they are in the right locations before you load it all up or it probably won't work.

I happen to have a parts Smash TV board here (bad corrosion damage) that I'll list the jumpers out for. Hope you find them helpful.
