Fatal error: Hunk Alloc: bad size
From Quake Wiki
The map or mod you tried to play requires more memory than Quake allocated by itself. You need to tell the engine to use more memory, append the following option to the commandline:
|Engine/EXE||32 Megabytes||64 Megabytes|
|quake.exe||-mem 32||-mem 64|
|winquake.exe||-winmem 32||-winmem 64|
|glquake.exe and any glquake derivate||-heapsize 32000||-heapsize 64000|
64 Megabytes should be more than enough, 32 Megabytes will be enough in most cases.
