What own made rom can we upload?

I noticed a topic asking if we could upload rom files a litle above so i was wondering if there was a list of what we could upload as far as the rules go(like playstation or wii roms)anyone can give me a list?

you can upload any rom you want, as long as there isnt any topic of the same game, and you post it in the right place. one thing though, if you start to upload nds games, the nds section follows a specific format in which to post the threads
