Unfortunetly I'm using MAME to play both of these great games...
I'm not sure if its just my computer or if slowdown was inherrent to the actual arcade version but whenver it starts to get semi-manic with bullets and several enemies on screen the game will slowdown quit a bit.
I know there are issues with the video emulation in MAME for these games at the moment, so I don't know if that could be the reason, but anyways here's my computer specs, tell me what you think.
Dell Inspiron notebook
1.5 GHz
512 MB ram
ATI Radeon X300 64 MB VRAM
Win XP Home edition and MAME32 for Windows
Perhaps there are even some MAME settings I could tweak. What are some good default setups you guys would recommend for me to use?
