I would note that modding a game like this would be harder than modding a game with actual mod support and harder yet still than making the same stuff from scratch in your own game because you need to also study the original game to understand how it works before you can just go modifying it, on top of understanding the more janky techniques needed to get things to work when injected into the game. so either modifying the original dll or injecting new code I'm sure you could do it. like the games code is all laid out for anyone to see in a completely non-obfuscated manner. and like realistically im pretty sure you could totally overhaul the game to be like an arcade game with enough effort. and just running that when nobody is playing. A demo mode might be easiest to accomplish by just recording game footage and doing it up like a demo screen rather than making some simple ai to play the game or something.

Sorry for a late response, i don't check reddit very often.Īnyway, as far as it goes i think anything is possible, just a matter of whether or not you want to put in the time and effort.
