Why are you suddenly so obsessed with this issue that you're cross-posting about it on multiple forums, and dragging someone else's thread off-topic about it, no less?
Sorry Just, it was not my intention, but since I thought the subject of this post was related to the issue, I thought I could find some answers about it here. And because nobody answered my post on MAME Chat forum.
Pit-Fighter is my favorite game and I want it "perfectly" emulated, if possible. And since I play this game a lot, It kinda bothers me. That's why I'm looking for clues over this bug. That's it.
