Yes it just happened to me... now how do you make Yamagi run the Quake 2 Expansions? also is there a way to improve texture quality? and by that I mean something to replace the texture themselves not just an aliasing method like the one included..
I had to revert back to v5 Yamagi since v6 didn't work.
To get the expansion packs to work, you need to create shortcuts to Yamagi's version of quake2.exe.
So the Target path should say:
quake2.exe +set game xatrix
quake2.exe +set game rogue
If the music doesn't work, make sure it's located in ...baseq2\music and try renaming the files to "02.ogg, 03.ogg" format.
