Illegal Instructions

NOTE: This document is now out of date, as should be updated to the new mnemonic and register naming

The entire opcode table has been evaluated on Pokemon Mini units and new and exotic illegal opcodes have been found.

These opcodes are not officially supported (they are not used by commercial games and not even found in the Pokemon Channel emulator) and can produce random results or crashes in some cases. The illegal opcodes have been documented on this page's Discussion page. ''' THIS PAGE IS IN PROCESS '''
