http://uploading.com/files/37ef6da3/PROJECT.7z/ Yes, I am using the PsyQ assemblers for this project. I would use the SNASM family, but I can't seem to find SNASMZ80. I'm using official Sega libraries and stuff to try to simulate the development process for a licensed developer as much as possible. Anyways, my problem is that it isn't finding _getjoy6, even though it is defined in UTIL.H which is included in main.asm. Can anyone help me?
