Spring RTS Engine

The watch replay doesn't seem to be working, when I press watch replay it brings up the script selection dialogue.

try adding "lc=8 pb=3" in the parameter box, then you get a gain with no cpu nor memory increase.

For me this is the best combination of switches for 7-Zip when compressing maps:
C:\"Program Files"\7-Zip\7z.exe a -r -mx9 -ms=e -mfb=273 -mlc=8 -mpb=3 map.sd7 mapfiles\*

You can also include those last 2 parameters in the GUI in the parameter box as follows:
lc=8 pb=3
