damn thats a really really nice explanation of romcenter and dat files t. that helped alot especially with the patches explanation also. im gonna get right on that. ok a few questions, when i scan for roms, sometimes it shows it with a small x in the corner for example it will show some yellow or red zip/rom pictures and some yellow or red with a small x. what does the small x mean? Also, some say missing files, so i went to romshare and redownloaded the rom but is still was missing the same files. So am i gonna have to actually have to search for those individual files? As far as in romcenter, everytime i saw it say "bad name" i selected it and chose "rename rom" and it looks like it fixed it so hopefully thats what im suppossed to do. Now i applied the pro patch to fba_26_08 with lunar and when i run it, it doesnt load, so i replaced the.xbe file with just the fba_26_08.xbe without the patch and it doesnt load either. Do i have to clean something out the hdd for it to work?
