I've made an .ent file for id3.bsp also known as the "DM6 Arena" from classic Rocket Arena but actually contains:
- DM6
- DM3
- E1M5
- Start room of start.bsp

Give it a try at and feel free to include it if it works out:

Copy ID3.BSP from arena and put this .ENT file to the same folder. In ezQuake you have to set sv_loadentfiles 1

It seems like the lift in E1M5 doesn't work but maybe because i only testet id single player.

I don't have id3.bsp
Why not try it out and get it working in pro-x?

I allready tried it in pro-x it seems to work quite well.
I've uploaded a complete package including the bsp (It's from final rocket arena, orginal .txt is included):

(I've updated this to fix the telporter in E1M5)

cool! will give it a shot, cheers

Ok I've another one this is probably this is defintily oldschool and was build for the multiarena mod back in the days. I've made it pro-x compatible it contains 4 classic rocket arenas and a nice selection area. I just made the .ent file.
Download BSP and ENT here: http://tc84.net/qw/marenarg1.zip

The following arenas are included in this map: (All Duel)
- SpongeBath
- Rocket Jump This!
- Edge of Insanity
- The Wicked Empty Base

You may not recognice the names but you all know the maps when you see them

TcT, yeah i figured that out aswell, the id3 map having 4 arenas, when i working on prox versions of the ra maps

But i did not know that there was a marena multiarena map, would have been nice to know before i used all the time converting them
