okay, fair enough and sorry, but ive got nothing more to say than above. i cant guarantee it works. i would not buy the product on the assumption it works with gameex.
I don't know about the other frontends, maybe hyperspin v1 but that is going to be a complete pain in the ass.
The newer ones are more for kiddies without real hardware.
This kind of thing is dying unfortunately. Without a CRT which died many years ago can't get close to the real thing anyway. Its nice to have proper four way etc though but probably more drama than it's appreciated.
ive not looked at it but fba may be the solution.
32 bit gameex will likely work and its no problem running 32 bit version. It is still updated but i just cant confirm it works which is why i suggested talking to ultimarc. Maybe they could spend a few minutes and test? In there interests, no? I am happy to help but little else I can do.
About a thorough answer as you are going to get anywhere in 2025.
