JKLauncher

This resolved the weird artifacting I've experienced in JK for years on my ATI Radeon 9550. Always made getting a good screenshot tricky as I had to wait for the artifacting to be at its minimum (or I had to spend time in PhotoShop). The artifacting didn't impact gameplay, so I never really worried about it.

Anyhow, to get this working on Win9x without having to modify your JK executable to point at a renamed ddraw.dll (so, for this to work by simply dropping ddraw.dll into your JK folder on Win9x) navigate to the following place in your registry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\SessionManager\CheckVerDLLs

Find ddraw.dll in the list and rename it (I renamed it to _OFF_ddraw.dll so it'd still turn up in searches for ddraw.dll) then restart your computer (this may not be required, but I had to before JK would start using the dropped-in ddraw.dll file).

Yeah, I was a bit surprised with the artifacting way back when I got the 9550; before that I'd had a GeForce3 ti200, and then a GeForce4 ti4200, and then a Radeon 9600 (the 9550 is essentially an underclocked 9600 with no fan). It was odd when moving from the 9600 to 9550 that problems cropped up.

I have half a dozen computers; the oldest (built in 2001) still runs 98SE and I love it. Look up KernelEx and RP9 if you want to know how I run modern software on 9x. All the other (much newer) machines run XP (varying versions depending on which license was bought for which machine). The 9x machine is still my favorite, even when up against a multicore, 4GB DDR2, nVidia GTS 250 beast. I have a 1.3 GHz Athlon, a whopping 512MB of non-DDR RAM (underclocked to 100 MHz), Radeon 9550, and ~600GB of hard drive space (120GB IDE, 500GB SATA via PCI SATA card) in this bad boy. It's on 24/7 and has uptimes measured in weeks.

The GTS 250, to my surprise, renders JK just fine aside from horrible texture color banding.

Works great in XP, but not in Win7 x64, so probably not Vista64 either.

Unfortunately, this doesn't solve my personal frame rate issue with transparent surfaces. (on 3dos it seems) For example, in DS3, because of the multitude of bacta tanks and JKE having purdy transparent surfaces on them, my frame rate tanks if I happen to look at them. I had long ago changed the bacta tank 3do to have solid surfaces and that had solved the issue, my frame rate was then capped at the refresh rate. The glass tunnel or water didn't seem to affect frame rate at all.

Awesome job none the less.

Groovy... Works if I use the -windowgui command line option. The game then renders properly in fullscreen, but the menus are in a window.
