A Bird & A Sign (Virtual Boy WIP)

Hey, since GoSub 3D is done, I thought I'd make a new Virtual Boy game. This one is based on my webcomic about a bird and a sign stuck in the middle of some desert somewhere. Since I don't have a Flash Boy, I'd like someone to test this for me on real Virtual Boy hardware just to see if it's OK. It works fine on the Mednafen emulator, but not so well on the Reality Boy emulator, and I don't know which is more realistic to replicate actual hardware. Anyway, to follow the progress on this game for every little update I add, I'll be updating this website, where you can get the ROM and source code. Here are a few temporary screenshots (the in-game one will definitely not look this bland. This is just a test to see if I could get everything working OK. Also, tell me how I'm doing with the jumping code, I'd like to know.
