The Nintendo 64 version of Transformers: Beast Wars Transmetals features an original character, Megatron X, who appears as a secret boss in the arcade mode. In the Japanese release, Megatron X can be unlocked as a playable character by connecting to Kettō Transformers Beast Wars: Beast Senshi Saikyō Ketteisen via the Transfer Pak. However, Megatron X does not stay permanently unlocked, and is only accessible if the GBC game is detected at startup. And since the Transfer Pak functionality was stripped out of the North American version, there's no way to play as Megatron X in that version at all.

Whether as a boss or as a playable character, Megatron X has significant gameplay buffs compared to the rest of the roster. He has twice as much stamina, and twice the Energon Resistance Gauge capacity, slowing the rate at which it both depletes and recharges.

This hack adds and permanently unlocks this exclusive character without requiring transfers with the Game Boy Color game.

2 patches are included:
- Megatron X unlocked
- Megatron X unlocked and you no longer need to hold Z to unlock Blackarachnia, Ravage, StarScream, and Tigatron
