Any ideas on this please? I'm not against upgrading to latest version if that's needed, but would rather understand/fix this if possible.
I noticed that in Missile Command my trackball is lagging, it kind of accelerates up to speed I think, which feels like a pause. (This is since change from XP to win7). I'm running groovymame 171. Note: The trackball works perfectly in other windows programs, and the pointer precision enhancement is turned off.
If I use a simple mame.ini there is no problem. My usual mame.ini with framedelay 0 is bad lag, but if I put framedelay 8 (in missile.ini) things are much better.
Also, I notice that the usual mame ini is running Missile Command at 98% whereas the simple one is 100%, why is that?
