GBS Control... inexpensive open source upscaler/downscaler
q6gt:
I built one a couple days ago. It was a big improvement for a Golden Tee Fore convert to lcd. The 8200 now accepts the 25khz vga right out of the Voodoo 3 card into the 8200. The image previously had a really bad shimmer or wave rolling through it, the gbs control had mostly cleared that up. I didn't add the clock mod yet but I'll give it a shot next week.

Yeah picture quality is noticeably better... I'm just having trouble with the interface behaving like it should. I'm going to build a scart connector this weekend and I can give it a real test with some 2d consoles.
Howard_Casto:
So those trim pots to adjust the rgb that are supposed to be optional? Yeah they aren't optional... you have to remove them. All of my problems cleared up after the removal. I've only tried the ps2 and snes but thus far the picture looks really good. It does seem to have an issue adjusting the screen geometry but you can tweak it a little manually so it should be fine. I obviously soldered up the scart connector but I haven't hooked up audio yet. I just got tired because those damn pots were such a pain in the ass. I couldn't get solder to stick to them well, so I couldn't desolder properly and had to snip them off. Likewise bridging the pins was difficult because I couldn't get solder to stick.
Anyway it looks great now. I threw in Maximum carnage for a 240p test. You see in that game the bad guys become translucent for a second before they die. The effect is achieved by alternating every other line of the sprite on and off rapidly. If 240p isn't handled properly you'll see lines. No lines folks so it's doing it's job.
I'll finish it up later on and I'll look into making/printing a housing. When I'm done I'll fire up the elgato and upload some test footage.

Shoot -- yeah I saw a youtube video of a guy building one of these and he removed the trim pots...
do you have any idea if this introduces any kind of delay?
Howard_Casto:
According to the people that made it about 1-1.5ms with some of the processing effects turned on... less without it. That seems about right but honestly, despite what some might claim you really can't notice lag until it gets in the double digits and for some people not even then so it's hard for me to know one way or the other. I can tell you that if there is lag there isn't a whole lot. Most lcd tvs, even in "game mode" introduce more lag than this thing is probably going to.
