I just recently became a screenshot adder and while going through games that are missing screenshots I have discovered that there are a lot of broken games especially in the MAME ARCADE section as well as some of the APPLE 2 games,I was just wondering if it,s possible for these games to be fixed while I understand that some of them may never be playable due to corrupt or missing files that can,t be replaced I would also like to know if those games can be removed since nobody will ever be able to play them.

I don't know of a way to fix a broken game and I think only tRIUNE can really do that. (I think, but anyone feel free to correct me if I'm wrong). 

But what you can do is to click on "Edit Page" that is found in the "Navigation" box located at the left of the game page. And then on the pop-up window, scroll down until you see something like this:



If it doesn't work at all, select loading. If it works but with graphic problems, select graphics. If it works but with sound problems, select sound and so on. If it works completely fine, then it should be "none". Afterwards, hit the submit button located at the top or bottom of the pop-up window page. You don't actually have to do this since you're not a game tester, but I guess you can do it if you want. This will help identify that a game is not working or having problems. 

I hope this answers your question.
