As some of you know, I'm making a guide for porting flamewing's S3K driver into Sonic 1. I'm trying to get it to be incbin'd, but it won't assemble. Every time I build I get this error: "ERROR: Second segment of sound driver at $1300 MUST follow directly after the first". I know what that means, but I've checked every aspect and it appears to be fine, so I have no idea what's going on. EDIT: So apparently, when you add any 68k assembly code before the Z80 code, it assembles just fine, but without it, it gives the error. Even if it assembles, it's broken. I even removed the assembled 68k code from the bin file, but no luck.
