would be possible to add in the future a cheat.dat for pinMAME ?? perhaps makes no sense but it would be nice to unlock the 'multiball' option for every pinball it is no joke pinMAME has its own cheat editor
It's not the easiest of emulators to setup and use...I've just reinstalled it for the first time in years and it wasn't a pleasant experience. So currently I have no plans for a pinMAME cheat file, perhaps somebody has but I wouldn't hold your breath.
There is a good installer pack that will install pinmame and visualpinball with all the required files to run, except of course roms and tables. But the problem is that is not that easy to get the tables and the roms at vj table's aren't up to date neither complete.
I have been playing a little with pinmame recently, I have to take a look and see how it goes, the biggest problem I think is that there is no real way to pause the on game of visual pinball and still syncing with the rom image running.
