Can't find original Assemble Arm.bat

I’ve decided to start looking at assembly hacking according to Tequila’s guide. However, “Assemble Arm.bat” is mentioned within the “Things you will need” section and referenced in a whole pile of other places. However, I cannot seem to find the file for the life of me. Can someone explain where to find it?

There’s a million copies of it in the skill system repo on Github.

Here’s one: SkillSystem_FE8/EngineHacks/SkillSystem/AssembleARM.bat at master · FireEmblemUniverse/SkillSystem_FE8 · GitHub

Great, thanks!
