yydebug file for the GM:S debugger so that you can edit variables live! (see here)Ģ.

Support for running scripts that automatically modify your data file (or perform other nefarious tasks) - this is the way to distribute mods, but creating them is a manual job for now.The output is accurate (except for the latest GameMaker versions), but it could use some more cleaning up of the high-level structures. This means you can add any custom code to the game, either using the built-in GML compiler or GML assembly. Allows for code disassembly and editing.An editor which lets you change (almost) every single value, including unknown ones.Properly handles all of the pointers in the file so that if you add/remove stuff, make things longer/shorter, move them around etc.

Can read every single byte from the data file for lastest version of Undertale, Deltarune, and most other GameMaker: Studio games (GM:S 1.4 and GMS2 bytecode versions 13 to 17 are currently supported) for every platform and then recreate a byte-for-byte exact copy from the decoded data.UndertaleModTool is a modding tool for GameMaker games, like Undertale and Deltarune. if it is a exe you need first to decompile it using the decompiling tool for older version of game maker. EXE or the data.win file and it will work. * (Seeing such an amazing tool fills you with DETERMINATION.) My Game Maker Studio Decompiler and Undertale resource thing.
