I don't know if this will really help, much, but you could store *changes* in joystick direction. ie: Left X 20 frames Up X 10 frames Right x 50 frames Assuming Left/Right/Up/Down/Jump that's 5 bits + 1 byte for # frames (max 256 frames at a shot). But you can cheat, you'll never have Up+Down+Right+Left so 1111 can be jump and you're down to 1 nibble for the directions + 1 byte for # of frames. So you can store 2 directions changes in 3 bytes. If you can set aside even 20-30 bytes you can get a pretty complex set of movements. I dunno if that's enough, or you have that much RAM but I thought I'd mention it.... Chris...
