I'm trying to run ecoquest 2: lost secret of the rainforest and it goes back to windows. Then I tried running it in dosbox and while still in dosbox, it says that I need 207088 more bytes to run. Where do I go to free up more space? I'm on an XP with 512 MB of RAM. I dont know if this will help but this is what the config file says:

videoDrv = VGA320.DRV
soundDrv = MT32.DRV
audioDrv = AUDTHUND.DRV
joyDrv = NO
kbdDrv = IBMKBD.DRV
mouseDrv = STDMOUSE.DRV
memoryDrv = ARM.DRV
minhunk = 500k
language = 1
patchDir = .\
cmd = sierra

Also, does anyone know where I could get another copy of the game besides GameTZ.com? I think theres something wrong with the resource file on disk 2 or 3. I REALLY love this game and I'd like to play it again.
