Can you provide the disassembly (containing also opcodes)
from the instruction where you give the command to
the RTS instruction?
"n subreturn" should create breakpoint:
CpuOpcodeType=%d :once :quiet
Where %d is code for CALL_SUBRETURN, which maps to:
Uint16 opcode = STMemory_ReadWord(M68000_GetPC());
if (opcode == 0x4e74 || /* RTD */
opcode == 0x4e75 || /* RTS */
opcode == 0x4e77) /* RTR */
Could you add some other breakpoint into middle and check
whether above breakpoint is set (with 'b' command)?
(code for above is in src/debug/debugcpu.c)
