Yes, you can edit the categories for you games in 1 of 2 ways. I have tried method 1 and it works. Method 2 should also work, but I have not worked with it. 1) Create a custom CatVer.ini file and use that when updating the list in GameEx. I created one while back and just uploaded it in the last week. I don't know what thread it was in, but searching should produce a result. Basically, you just take your default catver.ini file and edit the categories appropriately to reduce the number of list items. I found having 1 game in a category and 6 categories for the same type of game stupid, so I simplified it. Again, I really recommend at least checking out what I did. 2) Perhaps easier if you know MS Access. I didn't know how GameEx implemented categories when I made my custom CatVer.ini file. Apparently, if you go to the MAME.mdb file (I think) in the DATABASE directory, you should be able to find the categories listed. You could just do your work there and probably have a much easier time than I did. Good luck and let me know if you have questions. It's been a while since I built my file, but I think I have all the files I used, so I might be able to help with some questions. Also, there are some new databases that nologic, Stu and myself have been building (well, mostly nologic and Stu) that might be a good resource as well. The topic has been active recently, so you shouldn't have too much trouble finding it.
