As of 9/12/2016,
I have the Steam Version of SSZ : Directors Cut, updated to its current version they offer.
Been using Directors Cut V1.00 Trainer +5.
It works for me.
A sequence I have got to work is:
Open and Run Trainer, but do nothing else........Run SSZDC from Steam.....Load game, select campaign, and get to level select screen......Alt+Tab to Trainer.......enter password into Trainer and Activate, but do not activate any cheats......Alt+Tab back into SSZDC.......SLOWLY, press each F# Key for each cheat you wish to activate, give it 3-5 seconds between each F# Key press.....continue on with game.
Notes:
1. Even with the cheat activated, Infinite Thrusters did not work for me. It seemed to drain slower, and recharge quicker, but was not infinite. With all of the upgrades unlocked, its enough that it wasnt an issue, but for the "Torpedo Level" early on, it ran out on me.
2. Something for Flex would be nice to include. Im assuming the game wouldnt allow infinite flex or you would have included it (You guys seem to include alot of things when you can based on other trainers Ive used). But maybe something that slows the drain rate, or increases the Flex gained per each kill. Just a thought / wish.
3, 4, and 5. This is an AMAZING gaming site and resource, thank you for your work!!!!!!!!!!!!!!! I had a Game Genie for my NES and SuperNES as a kid, and you are the closest thing to it!
