Unfortunately, not as far as I'm aware. If you could make bepinex load my DLL without needing it to be a mod, it might work, as long as bepinex doesn't modify parts of the game that I hook into. Sadly, I can't promise that, or help you do so, as I don't develop for bepinex.
This mod was made to be a very small, simple, and lightweight trainer, and I doubt I'll ever rewrite it for a mod framework, especially as I'm already aware of two different (and incompatible) ones, which would mean I'd need to maintain three different versions of it. Sorry about that.
