Trainer history?

this may be impossible to find out but does anyone know what the very first game to have a downloadable trainer was? i don’t mean first added to wemod, i mean first ever created.

My guess would be original xbox not sure what game
There was earlier cheats but not a trainer

Trainers have existed since the '80s. The Wikipedia article doesn’t mention anything about the first trainer, and my searches are coming up empty. I’m curious too!

The first downloadable trainer would have come later though. Trainers were made before they could be distributed to others over the wire.
