I finally got the emulator to work only to encounter another problem: when I open the ROMs to play them, they move very slow (like it's in slow motion). Computer games do this sometimes too but all the ROMs I have tried do this. I have a 1.4 Ghz Athlon with 256 MB of SDRAM and my OS is XP Pro. I have great video and sound cards with the right drivers as well as the latest version of DirectX. Please let me know if you have any ideas as to what may be causing this. Thanks.
