So, it seems the 99 energy cheat seems to stop working after a while. Not sure why, probably just memory locations changing or something. But every 10 or so fights using it I usually have to quit and start again with a fresh launch of the trainer to have it work again.
it's because this game is programmed with cracker jacks kiddie level programming game kit engine that was designed for asteroids and such. We've had to do ridiculous stuff to isolate the values.
best,
Cal
