I discovered Ms. PacMan some time ago, but you don't see many of that game in arcades. Then I did find out about
mame (version 0.145), available on my Linux (Ubuntu) machine and about running Ms. PacMan and that works.
When I save a game (so I don't have to start from the beginning every time (so to improve more difficult levels) and then restore the game, the game in MAME resets and I have to start from the beginning.
I have read here about games being updated to support save state and also somewhere that saving was removed from MAME .100. I also tried to compile an older MAME version 0.99 (which should support saving), but it has no Linux support. And AdvanceMAME (1.2) does not compile because of configuration file problems that don't seem easy to solve.
Should I try harder to get an old MAME compiled, or is this saving of Ms. PacMan not going to work on Linux anyway?
