How to Unlock Trainer
- Start stage 1.
- Grab one of the rubies in the beginning.
- Now you have to jump at the bonus blocks in order, in a specific way.
You jump left at the first block...
jump right at the two lower blocks...
jump left at the higher block...
jump right at the next block...
then jump left at the next two blocks.
Remember, these are all in order.
You then get a trainer/cheat menu that allows you to have unlimited lives, unlimited time, set the status of Giana, and choose which level to play in without a password.
Speaking of passwords: the passwords on the Zero are different than the PC version. Believe me, I tried.
