Simple. DAT's don't work with GlideN64, we have HTC's now. What DAT are you trying to load?I still don't understand. I was able to get .dat files working for Glide64 so I like to think I know at least a little bit about what I'm doing, but GlideN64 I can't seem to work. I did what the tutorials said, put the folder in "cache" in the GFX folder and set both paths to that folder where I need to. I tried both public release 1.0 and 2.0. What am I doing wrong?
