The build provides one-on-one fighting with directional attacks, special moves, blocking, finishing inputs, and a roster drawn from the Mortal Kombat arcade design. Some fighters, stages, transitions, or finishing behavior may be incomplete or different in this beta, and the ROM itself is the authority for what is playable.

Save frequently and record the fighter, match, and ROM marker whenever behavior differs from the final game. Practice inputs slowly because beta timing may change, keep beta saves separate from commercial European data, and do not interpret a missing transition or ending as an emulator fault without comparing the final release.
