First bit of post is a request for enlightnment, the second part is a quasi-bug report

First of all - Which one is the latest version?!
I have managed to DL all these files from various places (Which I can't remember):
+ fs2_open-01_20_2004.zip
+ fs2_open-03_05_2004.zip
+ latestrelease.zip (is a 3.5.5, support -t32,-htl; Does NOT support -jpgtga, -spec, -glow.)
+ fs2_open_r.rar (is also a 3.5.5, supports -jpgtga, -spec, -glow; Does NOT support -htl ?!)
And then there's all this stuff:
FS2_new_weapon_FX_v0.2e.zip
Launcher4.rar
mediavp356c.exe
TGA_Planets_FS2_v2.0.zip
Now, the Launcher4 seems to be the latest since unlike the fs2_open's there are only a few, and that has the highest number and no variants, but it doesn't seem to be 100% compatible with any of the fs2_open builds: They all either complain that
-htl is not supported or that
-spec and
-glow are not supported!
I have tried all 4, and they seem mostly similar as far as I can tell - one seems to look like the original FS2 whereas the other 3 look absolutly gorgeous. One also had this weird bug where waving your mouse over the Enter Mission hatch made it go all psychodelic now-and-again.
However they all crash at some point: I have played, at best, 2 and a half missions with each one before it just quits unexpectedly.
Additionally, the game 'pauses' a lot - usually when a large ship re-enters the viewpoint. It feels a lot like when I used to play FS2 on a Voodoo1 - the game would jerk like hell whenever a (large) ship re-entered the view because of the texture swapping.
Occasionally there will be a 'big' jerk, usually when a) a Large ship is entering and b) A voice is playing, and 9 times out of 10 I will get 1-2 more frames out of the game then it crashes back to the desktop.
I tried installing FS2 to see if something's gotten corrupted on my Windows 2000 side (The install on my Win98SE side has been there for the better part of 4 years now I think

), but it still did the same thing.
