So i tried opening my game rolling bird with undertalemodtool and it works. Looks like me from the past did not compiled it in YYC.
I already forgot most of game maker things after all these years, and undertalemodtool's UI is fairly confusing to me, but the all the needed sources are here and functional. the network related functions are at the object called "GMS" and all the scripts in the script folder are related to these network functions alone, as I did not used external scripts for in-game functions. you may need to entirely remove or modify the leaderboard screen to not use this network function to make the game work properly without errors.
Hope this helps, my game is fully hackable with this tool.
