Based on the available V30MZ documentation and hardware verification, the V30MZ (like the 80186, unlike the V20/V30) respects the immediate argument provided to AAM and AAD opcodes. Most WonderSwan emulators get this wrong, but emulating this correctly is required to enable certain modern C compiler optimizations for homebrew.
