I got a Super Grafx from ebay, and it seems to have a problem. It will play normal pc engine games completely fine, but won't play the original Battle Ace card that I have, or supergrafx games from my turbo everdrive (v2.5).

It will load one of the Super Grafx games from the everdrive (Aldynes), but displays it with corrupted sprites and backgrounds. Other games just give a blank screen. 

Is this a problem that other people have come across? Is is possible that the additional Super Grafx GPU has failed somehow, but the base PC Engine hardware is OK?

I'm going to contact the seller, but wanted to check to see if this was an issue that other people have come across, as I know that some versions of the everdrive don't work well with SuperGrafx (but my v2.5 should). 

Thanks for any advice!

There's a switch on the rear of the console that determines pc engine  or super grafx mode, try that.
Clean the hucard slot by using an iso soaked tissue wrapped over a credit card or something, be careful
Try as many original hucards as you can, if you get corrupt graphics all the time maybe fault with RAM etc

Wow - thanks so much gojira54 - I had no idea there was a 'make everything work' switch on the back! 

It's working perfectly now. Great games - shame they didn't make more. 

Can you RGB mod Super Grafx?

Yep, you can RGB mod the Super Grafx in the same way as a Duo/Duo-R/Duo-RX, straight from the Hu6260.
