I'm having trouble loading up japandm. Every time I try to run it I get a ZMAlloc failure. I've checked my com_hunkmegs and it's at 300, so that shouldn't be the cause. Has anyone else had this problem?

I've not had this problem, but I've heard from somewhere (hell if I remember where) that high com_hunkmegs settings can do some silly stuff. Try setting it lower and see what happens --I run 192 and have never had a problem with it. It's also noted in the manual that anything higher than 128 or so really isn't necessary.

I don't think it could be that. I tried it by opening up the map with com_hunkmegs set to 300, and it worked fine. However, I usually run it at 256, and when I try entering a server for the first time I load GenArena it says "No or Bad Challenge for Address," but reconnecting fixes that. It never did that when I was on my stepdad's iMac (Where it was set to 192), so maybe my small problem's due to my com_hunkmegs being a bit high? Ah, well.

Zmalloc is not caused by com_hunkmegs.  It's caused by com_zonemegs, which there's no way to increase without modifying the executable.  You get the same problem trying to play MPTerra2 using Gen.  I know because I tried it.  You can try to set com_zonemegs all you want but it will ALWAYS latch, and NEVER change from the default value of 16 no matter what you do.  I confirmed this by modifying quake3.exe to up com_zonemegs to 32 from 16 and voila, problems vanished.

This is part of the reason I want Gen to have its own executable, and why I posted the "who uses a Mac" poll.  You see, I can most likely compile for Linux (I'm damned sure going to try), and I know I can compile under win32, but I cannot compile the Quake 3 executable for MacOS.  I'd need an actual Mac for that, and I don't have the money for one.  There are just some things I can't fix by optimizing in the .qvm anymore.

Actually, false alarm  Slipgate - Shifty I was beginning to get this problem with every map I tried to load until I discovered that for some bizarre reason, my sv_maxclients had been set to 3010. I reset it to 10 and it's back to normal. Er, thanks anyway!

Pho: How did you increase the zonemegs? Did you use C++?

I made the following change to the Quake 3 engine source:

qcommon/common.c:
Code:
#define MIN_DEDICATED_COMHUNKMEGS 1
#define MIN_COMHUNKMEGS 56
#ifdef MACOS_X
#define DEF_COMHUNKMEGS "64"
#define DEF_COMZONEMEGS "24"
#else
// Phoenix
//#define DEF_COMHUNKMEGS "56"
#define DEF_COMHUNKMEGS "144"
//#define DEF_COMZONEMEGS "16"
#define DEF_COMZONEMEGS "32"
#endif

Compile Quake 3 and voila, no more zMalloc failures whatsoever.  I also boosted min hunkmegs for non-dedicated.  I've been using this custom compile of Quake 3 Arena exclusively now for a while and I've not had any problems with it.  This is good because in essence this is an alpha test of standalone Q3 compile behavior.  I get a feel for how the GPL build behaves vs the official 3.20 build.  So far its been behaving... well, exactly like Q3, minus Punkbuster of course.

Oh, and for those who might be thinking "Pho cheats!  He h3x0r3d Q3!", um, no.  I wouldn't do that.
That's what magic Phoenix powers are for.

I didn't know the engine source was out - where can I get it?

BTW Who needs PB anyway?

Folder: ftp://ftp.idsoftware.com/idstuff/source/
Direct download: ftp://ftp.idsoftware.com/idstuff/source/q....32b-source.zip

Alternately, you can get it from one of the following sites.  Id's FTP site is usually slow since it's always very busy.  If all else fails, google "quake3-1.32b-source.zip".

Thanks  Thumbs up! Do you need C++ to compile? Pardon me, I new to this stuff.

The source comes with a .sln file, which is designed for Visual 2003 .net, though if you have Visual Studio 6 there's a thread regarding compiling it here:  http://www.quakesrc.org/forums/viewtopic.php?t=5405

If you're compiling it for Linux or MacOS follow the instructions Id left (I guess).  I'll know soon enough for linux, once I can get my freaking sound to work...
