Hello everyone,

Recently built a retro PC to play some older games, which has been quite successful across the board, except for one game. Having fond nostalgia for the game "Gex: Enter The Gecko", my friend gifted me his old copy he had laying around. I've been trying to get it to run on my system, but it won't decently work for the life of me.

My specs:
- Windows 98
- Pentium III, 866mhz
- GeForce 4200 Ti 128mb
- 512mb ram
- Soundblaster Live!
- IBM P76 Monitor
- Nvidia 45.32 drivers
- DX8.0

Here's the timeline of what I've tried:
1. Installing the copy I was gifted, which seems to be the 3DFX version. Won't start due to Glide2x.dll missing (obviously).

2. Using Zeckensack wrapper, ironically the best results of everything I ended up trying. The game launches and I manage to play, but sadly after playing successfully with more or less complete graphics, I get permanent graphical glitches even outside of the game. I get these pattern type marks all over the screen, even simply on the desktop, which only go away after reinstalling my GPU drivers and coming back every time I reinstall Zeckensack and launch Gex. Thus, not being able to use Zeckensack as a sustainable option.

3. Tried using dgvoodoo 1.5, isolated in the Gex folder. The game launches but crashes after the intro screens to a "main: grSstOpen failed" error. Every other attempt to restart the game afterwards results in an "illegal action" error, and freezes the system, needing a restart to fix.

4. Noticed there is a D3D patch for the 3DFX version of the game, managed to source it and used it to replace the gex3d.exe on a fresh install. The game tries to launch, the screen has a black screen flicker and goes straight back to desktop without anything else happening.

5. Did all possible tests in dxdiag, and everything appears to be fine.

6. Gave up, and set my mind on purchasing the D3D version of the game hoping it would change something or work better than the patch, for some reason. Found it, bought it, installed it... Surprise: it didn't work. I have the exact same issue as with the D3D patch for the 3DFX version. The game tries to launch, flickers a black screen and goes back to desktop without any error messages or anything happening.

7. Booted into BIOS and limited AGP mode to X2, disabled fast drive etc... basically tried some things I saw could work with other similar issues in similar environments, but nothing.

Tried launching the game in both my default settings, as well as changing up the resolution, as well as changing color depth, refresh rate for all these steps, the results appeared to be the same every time. Getting desperate out here, feel like I've exhausted my knowledge as to having a go at making this work *sigh*.

Would anyone happen to have an idea at what I would be doing wrong, or have other suggestions? Thanks a lot!

Likely the Ti 4200 is too new, I found that with late 90s titles with mine, my TNT2 and V3, I never have issues with.

By chance I have a 850mhz PIII, a TNT2, V3, Ti 4200, so if you wait two days I will test the direct3d version on the nvidia cards.

Hello there,

Thanks for the feedback. If you are willing to look into that, that would be great, I'm curious now.

OK here goes, doing this on a phone so may make grammar errors.

Test system - Abit BH6, 256mb RAM, Pentium II at 266MHz 66mhz fsb, Pentium III at 850mhz 100mhz fsb, 3DFX Velocity 100 8MB, Ti 4200 64mb, Riva TNT2 Pro 16mb - both the Riva and Ti using 31.40 drivers.

The game vanilla, no patches, default 3DFX Glide mide with the Velocity and PIII at 850 - framerate too fast.

Same configuration as above, but with 3DFX patch applied, slower framerate, but erratic and jumps a bit around speed wise.

PII at 266mhz, velocity, 3DFX glide, vanilla game too fast, once patched with 3DFX patch, perfect speed, no hiccups.

Same configuration above but with D3D patch and running D3D on the Velocity, slow and stuttering.

PIII 850 on the Velocity in D3D - perfect fps.

PIII 850 with Ti 4200, blank screen when launched.

TNT2Pro with PIII 850 in D3D mode, same drivers as Ti - perfect fps

Conclusion, if using 3DFX glide via Voodoo card, you need a slow CPU and to patch with the 3DFX patch.

If using a fast CPU in D3D the 4200 is too new and does not work, Riva TNT is the most compatible.

3DFX glide mode with patch, slow CPU needed.
D3D mode, fast CPU needed.

Legendary, you're doing god's work. Thanks for putting in so much effort.

I suppose slowing down my PIII won't be of much help in this case then. I still have an AGP Nvidia Tnt2 m64 32MB laying around, but only one AGP slot. Might look into finding an older PCI GPU, and try to set it up in parallel to the 4200 Ti.

My pleasure, enjoyed doing it. Happy gaming.
