hi lightgungamer! dgvoodoo is a set of graphics wrappers which can upscale old games or make them playable on new hardware. if you use the widescreen hack on hotd2 pc as well as dgvoodoo then you can get really nice results - i'm running it at 2560x1080 on my ultrawide monitor with the correct aspect ratio. it works great with a mouse, but seems to interfere with the aimtrak, so that doesn't work. the cursor can be hidden as well, so it would be pretty much perfect if the aimtrak worked!
Also - i havent tried the wii version. thought there might be more lag than the native PC version?
