AoE: DE Custom game speed?

Does anyone know of some way I can set the game speed to maybe… 1.2?

1.0 is too slow and 1.5 is too fast for me. It should be a simple thing to change if it isn’t hardcoded and I remember some tool for the classic game that did this?

EDIT: Tried the config ini in the user folder but that didn’t work. I set the game speed to 12(1.0 is 10 and 1.5 is 15, I checked it) but even marking read only the game still starts at 1.0.
