I had this idea the other day, and I was wondering if it could be possible. I don't know all that much about emulation, but after playing around with MGBA, I found that the games are constructed in "layers". I was wondering if this could be utilized to make a GB emulator that plays games with the 3d effect, like the 3d classics series. I know that the 3d classics games had some things seperated to make it look fancier and have more depth, but to have this at a basic level for GB and GBC games would be neat. Even though it would probably look weird sometimes, I think I would be a cool affect. Is it possible?
