You've lost a nickel! It was a problem with my signed-offset branch function where a bad cast was allowing 0x80 (-128) to overflow. It was really fun trying to troubleshoot by hooking certain memory accesses and subroutines, but what wound up fixing it was investigating the crash of Blargg's `instr_test-v5/rom_singles/11-stack.nes`. Thank you for your help!
