3 of my AES carts glitch on both systems!!

I have an annoying issue with 3 of my AES carts glitching on two old style Neo Geo systems with the daughter boards serials between 20,000 and 30,000. The carts are Samurai Spirits 2, Fatal Fury 2 and KOF 95. The glitches are consistant in the same places on parts of the games and are similar to the old NES glitches of what seems like graphic corruption.

Fatal Fury 2 has a glitch in the backgrounds right in the center, also in the character select screen. Samurai Spirits 2 isn't that bad, just in the option menu and some small glitches in the backgrounds once in a while. KOF 95 has very little glitches in the fighting scenes but there are some more in the opening and when a character is finished in the white background.

I doubt this is an issue with the systems. I just find it hard to believe that my luck was bad enough to have 3 bad carts. I tried checking the solder points in the carts and also resoldered the rom chips in my Fatal Fury 2, no results. Anyone else been having this problem?

No, that's wierd. I have a low serial system that had the daughterboard (Jeff Kurtz got rid of it for me with his Neobitz mod ), and never had any problems with any games before or after I had it modded. Are you sure the contacts on those carts or the systems contacts aren't dirty? You may want to buy a can of electronics cleaner (the can with a brush tip) and give your system and the carts a good once-over. I tend to think it's your systems contacts however. Both systems may be dirty.

I cleaned the crap out of my games and my systems. The degree of glitching is exactly the same. Now here is something funny, the glitching is a little more mild after I installed a NeoBitz board in my 30,000 serial AES. Both systems have the old S-video stlye mod minus my Neobitz system now, but I also tried removing the mod completely and it was the same. The Neobitz board helping is very odd to me. Maybe something to do with the sync? Here is another thing as well, I had to use a 0.01 uf ceramic capacitor in the sync line to get my component video to work right, this is minus the LM1881. When I used the LM1881 it just gave me a scrambled picture in all video outputs.

Anyway, this makes me think it could have something to do with the power not getting through the carts as well. I wonder if it is just the rom chips in the carts. I guess it also explains that there could be forever recycled bad carts on ebay, I dunno.
