Emulator

I kept running into an issue where every time I opened the properties of a particular game, the menu would open wide enough to cover three monitors. Eventually I realised that the reason was because the game banner under the Info tab was stretching the menu extra wide to fit the high resolution image I had left in the games folder.

Easily fixable by ensuring your banners are the appropriate size, but I thought I should submit this as a bug report nonetheless, as it took me a bit of time before realising what the cause of the issue was.
