I need a chip (?) for Vs. Tetris. The colors are off!

I have a Vs. Nintendo. When I got it it had Vs. Castlevana chip/small board. Took it off and installed the 4 Tetris emproms ($20, ebay) and got it working but now the color is off.

Now it looks like an old video poker machine; billiard table Green with white display, some reds. I was told that there's a chip that can fix the color (black background and colorfull bricks). Any help?

do any of the dips do anything for Tetris?
 
But do make note of what Slots said. The dipswitches on the pcb will change the color schemes. And, the colors on Vs. Tetris are way different than the "regular" Atari Tetris. It took me awhile to get used to it when I had that game.
 
Code:
Vs. Tetris dip switch settings:
-------------------------------

I bet you're/he's using the RP2C04-0002 PPU (chip with the big aluminum heatsink) from the Castlevania daughterboard with Tetris. That would give color problems you can't fix with DIPs, since it is not the correct PPU for Tetris.

Tetris uses the RC2C03B PPU, and can also be used with an RP2C04-0001 with a "usable" color palette.

So Sage, in addition to setting the DIPs, you also need the proper PPU chip.
See John's excellent page for further info on which games you can use with which PPU's : http://johnsarcade.com/nintendo_vs_ppu_info.php
 
I switched the dips before we closed (fogot which ones, I think it was 6 on, all off) but now I have set it on "normal" mode, instead of hard tomorrow morning.

Cool Beans! Thanks for the help
 
Tetris doesn't show any high scores... and I got angry gamers at RQ. Anyway to fix?

It's been a couple years since I had it but I don't recall Vs. Tetris saving high scores. You should throw Vs. Dr. Mario or another good Vs. game in that cab and put together a regular Tetris cab with the Atari (?) pcb. That saves high scores. Although I believe the scores continue with each credit put into the machine so someone could keep feeding it quarters to build up their score.

Yes... it's using the Castlevania PPU (he only purchased the program roms becuase he didn't know about the vs. system design)
He should buy the correct PPU, as you suggested above.
