1) Timer: Float, the first memory addy seems to be pretty stable through playthroughs. My current addy is 06A4874C. Set it to 1 and all timer based challenges can be accomplished null sweat.
2) Mech Reactor: I've found that you can overcharge mech power with a 4 byte, set it to something like 40 or such and you can power all weapons and upgrades. Edit3: If your pilot has a reactor bonus just take them out Searching can be tricky if you've got a pilot with a +Reactor bonus. The address location changes with every island.
Edit: 3) Pilot XP: Simple 4-byte search. Once found set to 25 for first level, 50 for second. Most annoying part (for me): Units that don't do direct damage (grapplers and pushers).
Edit2: 4) Mech Hull: 4-byte, you can find hull pretty easily (especially with the use of the 2nd script!). Address location is persistent across islands.
Also new script works great. Thanks!
