recently i've download this game (skidrow version), about 2 days ago. Then i tried to find some trainer for unlimited weapons/ammo, unlimited durability, etc. Try to googling but only found promo trainer and beta trainer. The promo trainer didn't work and beta trainer made my game crashed.
I recently found a working trainer, go to GameCopyWorld dot com, and download the trainer by Armando, it's the only one I found to work, and now that I can stop the timer I can raid the slot machines and ATMs, as well as have infinite weapon durability/ammo, infinite survivor/player health, among other things.
So that is pretty much what you're looking for, until Computer Masster creates another awesome trainer and unlocker like he did for the OG DR2, enjoy!
