@roman126 I've running Pro Pinball Timeshock under dosbox (recalbox) on my overclocked RPi3, but also not really playable.
Sound is ok in my case, also the background CD tracks plays quite well. The issue I have is, that the game in general runs to slow. It seems the (emulation) speed from an RPi3 is too slow for such a late dosgame as Timeshock is.
In my case, I have 10-15 fps max. I tried to optimize a lot in settings, but I don't get it really smooth.
As from my experience, the last generation of triple A dosgames from 1994 onwards (especially 3D games) are too advanced for the RPi3.
As you already said above, it's also not possible to run the PSX version of Timeshock. I got it working on Retropie, but what I remember, they offer a second emulator core for PSX, with which it has worked.
But as the recalbox team is doing such a good job in general and also with the fast update intervals, maybe a further update will bring us on Recalboxos also a second (for ARM) or updated emulator core for the PSX, which covers the incompatible games.
