The only downside of the map is that it can't be chosen in the menu. So here's a small patch to address that problem.

It makes both maps playable in FFA and 1on1, and dm7 playable in Team Deathmatch. As a bonus, they can also be chosen for Last Man Standing in OpenArena.

Loved the two maps, I wish our dm2 and dm4 would look as awesome as these versions.
The maps play flawlessly in OpenArena.
