The FS2_Open_t build won't work for me. As soon as I either commit to a mission or enter the techroom, it crashes to desktop. The extensions I was using were -t32 -32bit -htl, but it wouldn't work. I should note, that I hadn't tried any previous tags before so I haven't tried HT&L on my system before. I have currently reverted back to PhReAk's latest _r build without any tags. My system specs are as follows:
AMD 800 (thunderbird)
ASUS A7V-100
256MB SDRAM-133
ASUS V7100 GF2-MX (pre 200 or 400) 32MB AGP
Also, I'm using a version of the nVidia drivers that is a few years old, since I found out that a more recent build was causing problems for one of my games. I haven't updated the driver since then (12.41 I think). I'd prefer not to have to update my driver, but it may be a contributing factor to this problem.
Later!
