I've got a nifty little idea for a feature in one of the next releases. Playing gameboy games on my PSP is really nostalgic for me, and I noticed that in a lot of emulators, if you choose to keep the original resolution, there is a lot of unused black space around the screen, yet if you stretch it, sometimes it loses quality. Therefore, what if there was a sort of gameboy themed frame in place whenever you played games in their original (or even the x2 stretched, since there are still black bars on the left and right sides) format? By this I mean there would be an image of a gameboy in the background perfectly laced so that the rom's image would show up in the screen. For gameboy games, there would be an original gameboy in the background, and for gbc games, you could have a gbc (preferrably the cyan colored one in my opinion, but I know the atomic purple ones were popular as well).
My topics are usually more articulate and have more depth than this, so excuse me if my suggestion sounds rediculous, but here are some quick proof-of-concepts:
Of course these arent nearly as good or as high res as they should be if they were in the actual emulator, I slapped these images together in a hurry, but you get the general idea. What do you think?
