I have been using Visual Studio Code to view our assembly code files (.asm) and have been annoyed at the other Motorola 68*/65* style syntax highlighters out there not matching our code. So I made my own. This one works best with .asm files (mostly works with .tpl, .lst, .mpt files too) and tested on T-LM, T-SMEC, T-SBEC .asm files.
The extension is not published on the marketplace, but you can download the .vsix file from https://github.com/jpcturbo/mp68asm
