 Update: Now contains a Quake2 Map to Prodeus Map Converter!

+Here are the steps needed to convert Quake2 Base1 to Prodeus:
+
+1. Buy, install and run Prodeus at least once.
+2. Download and extract Base1.map from https://icculus.org/gtkradiant/downloads/1.5/gamepacks/q2-example-maps-2004-12-06.tar.gz
+3. Download and extract quake2-neural-upscale-textures-2.0.1.zip from https://github.com/Calinou/quake2-neural-upscale
+4. Download MapConverter from https://github.com/rhulha/Q3BSPParser/releases
+5. If you want to decompile BSPs to Maps, I had great success using this: https://github.com/wfowler1/bsp-decompiler
