Looking for the MCP+ assembly code

[8bit-Dude]

Hey Guys,

In Atari Gaphics Studio, there is a cool video mode called MCP+ (see attached xex).

I can export MCP+ images from AGS as xex files, and they run superb on my actual 130XE.
However, I cannot find the ASM code anywhere (and AGS refuses to export ASM code for that format).

Would anyone know where I can find this (lost) ASM code?
