Map scaling

[Spengbab]

I was wondering if there was a way to scale the on-screen map, and the toggled one.

Firstly, I play on a low resolution (512x384), mainly because I want that nostalgic pixelly feel pre 0.50.

The minimap I noticed is rendered in the same size for just about every resolution, which sucks because the game was meant to be played 640 and up, and not 512. With the M key, the map can't even render at all, which gives a draw error of some sort.

I can live with a big minimap and an unusable one, but I was just wondering.
