I use a p2-400 BX system with a G-200 graphics card. Most games run at 100% so I seldom have to run with frame-skipping and the like.(posted 9899 days ago)My opinion is that recordings done with slow computers (emulation below 80-90 %), should not be allowed. The games are not supposed to be played this way, and the scores would certainly not be 'legal', in the sense that you probably wouldnt have achieved it if the games was running at full speed.
Hope the mame-team add a function that saves machine information/emulationspeed-information in the recordings.
