I need a more detailed information... in few words: where and when the MAME version has the issue that it prevents the progress in the game.
PS: I played for about 20-25 minutes and (for now) I didn't find any issue (but it's too early to draw conclusions)...
lets take for example this gameplay video -
https://www.youtube.com/watch?v=GeTwg5ulArQtypical signs of failed protection checks:
- 1st boss fight event may be missing, at 32:00 on video
- missing game event when visiting Edessot house, at 46:10. you just walk in house and nothing happens, game script/flow stops, and you cant progress further in game.
