last change | Add side-by-side x86+sh4 disassembly output Print SH4 state information and disassembly of the current block when crashing. Fix delay slot instruction in conditional branch not being marked as a delay-slot instruction in the branch-not-taken path. Rename REG_* defines in cpu.h to avoid conflict with translation defs |
