Chocobo World

Hi folks
Been playing (PC version) Chocobo World cause it's a great way to get rare items into FF8.
Anyway, have now reached level 100. Took me ages to work out you can only fight the final grim-reaper look alike if you have your movement meter set to 0. Have now killed him. my qyestion is - I have only received the first power-up at level 50. Seince then, nothing. If i keep playing on level 100 do i still have a chance at received them, or would I have to restart from level 1 again? If i do have to restart, how do i get the second two power-ups?

Alternatively, has anyone found out which hex codes to change in the save game file to get them? Have found the position for level, items, ID, health etc, but as yet the power-ups elude me. Only decided to hack the save game after playing the silly game for ages, but could not find where to change it! ARGH!
