ZSNES board

Well, interesting results. 640x480 Vesa 2 mode works as in DOS, but there is now a bunch of pixels stretched and smeared on the lower half of the screen. Hard to describe and I wish I could get a screenshot. After about a minute, I still did not see the flicker glitch, however. 320x240 Vesa 2 mode w...

Good question. Let me try.

Alone... like the blackness of DOS itself.

Still... there has GOT to be a way to fix this. I'd be willing to dig into the source code if necessary.

Lemme check on that running the DOS version from windows idea...

Am getting back to trying to find creative ways to fix this issue. I thought it might be possible to fix by using some VESA tools. I've experimented with all of the following oldschool DOS video tweeking utilities... VBEPlus VBEhz Nolfb UNIVBE (scitech display doctor) UNIRFRSH FASTVID ... while some...

I've been tweaking pixels, refresh rates and sync-on-positive and negative values on VBEHZ. I've trying to find a rhyme or reason for why this glitch exists. As far as VESA displays go, I can't find any value that directly affects it. In all this, I suppose I should mention that I've managed to stop...

Hmm. Univbe doesn't seem to work with geforces.

I wanted to hold off until I had a better understanding of how this VBEHZ program works, and I've had a good amount of time to tinker with it now so here it is... It actually works pretty well! I've really never seen the SNES so vibrant on a computer monitor before. So yes, the best settings seem to...

This utility has... dare I say it... solved the problem My god Kajuru! You rock rock rock! This problem has been driving me nutz for months and Crap! it just flickered. I swear someone is writing a sketch comedy about this! Hehehe... really tho... this utility give a LOT of control over display mode...

Facinating! I'll give this a shot. This eliminates the Ati cards tho. Ati in their infinite wisdom didn't make Radeons or even Rage cards Vesa 3.0. Only Vesa 2.0. Surprised me. Irk. :roll: Anyway, I feel that this may be a method of solving the glitch if I monkey with the refresh rates enough. Thank...

Hmmm. After going at this issue now for a long time, I suppose I should mention what I've found with triple buffering and zsnes, and the various cards I've tried in DOS since maybe this info will be useful to someone, perhaps with one of those ATI arcade VGA cards from Ultimarc or something. I've be...

Errr... well by experiment, I can say yes and no. I borrowed a Geforce FX 5200 128mb DDR AGP made by PNY. Cheap card, only 65 bucks new. I almost jumped for joy. It took a full 3 minutes of play before the flicker glitch appeared in Super Metroid. So yeah, still there, but very sudued. Very playable...

Yeah, seems to be something with the whole Geforce line, at least up to 4. I've tried the following AGP cards, and they all demonstrate the effect: Diamond Viper v550 TNT-based card 16mb Nvidia Geforce2MX 32mb Nvidia Geforce4Ti 4200 64mb (Asylum brand) Nvidia Geforce4Ti 4200 128mb (Albatron brand &q...

As far as testing the issue goes, I think all you need is a ZSNES dos setup with an NVIDIA card, probably any of them. It's not hard to duplicate as long as you have an NVIDIA card installed, in fact you can download a WIN98se boot disk and run ZSNES that way. The CPU speed/type doesn't seem to matt...

Yeah, all running in DOS. Haven't seen a force refresh rate in the DOS version. There's a huge amount of tweeks that can be done with Nvidia cards and triple buffering from within windows. I don't know if any of these settings carry over into the card after a power-off (to run DOS). I kinda don't th...

Greetings! It seems this glitch is already known, I read information about it earlier today from a Google search. Anyway, I should have read that before I purchased a couple of Geforce 4 TIs (with the assumption that perhaps the extra power/refinement would fix the issue, since I was using Geforce 2...
