Can you make the trainer so it works in the omega flowey fight


It wont let me use any of the cheats…could you fix this?


Does this not work with the DRM-free version? I’m getting errors when I link the game.

What error?

It’s telling me it’s not a valid installation. I redeemed my key on Steam so I got it working now. Also, the health cheat doesn’t work in the final boss fight with the flower monster.

Can you send me your save game? so i can check the final boss battle

Currently not working =(


No matter how many times I deactivate the cheats and reactivate it, it doesn’t work. I keep dying. Is there something I should do to make this work? Could there be something I’m doing wrong? (I recently got Infinity and signed up, so I’m new here :no_mouth:)

Undertale has recently been updated twice so, I think the trainer needs an update for the cheats to start working again.

Cheats aren’t working. Attempted with administrator mode and non admin mode from loading a save then activating cheats. Walterin may be right as they haven’t worked since from at least the last major updates.

Any idea when the Undertale cheats will be updated? I’ve been stuck on Undyne the Undying for a while and had hoped Infinity could help, but according to all these posts the cheats are incompatible

pls update this trainer. Tried to test it out on toriel but nothing happened. tried it again on undyne still nothing. even tried it on normal fights nothing.I did what the trainer said to do but it sadly dosent work.


Infinite Health is not working. (i did download a genocide save but it just doesnt work.) the other cheats work fine as far as i know.

it does not work at all fix pleas really disapointed
