I am using: x64, latest batocera, .chd files for dreamcast and tried all emulators.
My problem is that saving does not work properly
It is
1) not very fast (not the problem)
2) has a good chance of both crashing the game and killing the savegame.
Depending on the game this happens like 30-90% of the time, but definetly way too often.
Anybody has experienced this issue and knows a workaround/fix?
