v2.4 SuperGrafx Glitches
« on: February 20, 2016, 02:26 AM »
I tried using my v2.4 TED with a SuperGrafx and am getting serious graphical glitches in some games. I've tested No-Intro and GoodPCE versions of all roms, and I have my SGX's switch in position 1. I've tested on two different TED v2.4s with the exact same results.

Update: This turned out to be a simple insertion problem. After a lot of messing around, I found that my console needed the TED to be seated in a specific way. Now everything is perfect.

Super Ghouls 'n Ghosts/Daimakaimura: Occasional strange sprites and complete crashes in level 1.
1941: Sprite glitches
Madouou King Granzort: Boxy graphical glitches and lines through background sprites

Aldynes, Darius, and Battle Aces seem perfect. TG16/PCE roms are also unaffected by the glitches. Attached are a few pictures of some of the problems.

No, you can only play SGX games on a SGX.

I can now confirm that the glitches are due to a compatibility issue with v2.4 and the SuperGrafx. Today I had it tested with real SGX hu-cards as well as roms flashed via a 39LF040 cart, and they play flawlessly. Perhaps this is something that can be addressed through a firmware update?

I tested all those games on my 2.4 and supergrafx and had no glitches.  not sure why they arent working for you.

Thank you sincerely for testing those roms. This must just be a fluke with my console after all then.

I just got a super grafx and tried out my 2.4 TED on it - no problems with any of the SG roms for me.

I was finally able to resolve this. I cleaned the SGX's pin connector with alcohol, followed by deoxit. Now if I position the TED just right when inserting it, I can play SGX roms without glitches. I'm actually starting to think that the PCB thickness is the culprit, since it's never had an issue with real carts.

I'm glad to have the problem identified and essentially solved. I'll see if Krikzz will issue an exchange if he ever gets thinner PCBs in stock.

Hi!

I´m the same boat.

I´ll try to clear it like you wrote and will try to position the TED just right.... talking about it, how you did it?

And you manage to get a thinner version of pcb?

Thanks!

Mauricio

Hi SmokeMonster 

Can you explain how you position it "just right"? I tried many ways and still getting glitches. Same games as you mentioned.

Thanks

Mauricio

Remember also that I cleaned the cart pin connector in the console too.

I push the EverDrive in all the way, then pull it out slightly. Load Madou King Granzort to test if you have it positioned correctly, since the graphics errors appear in the first second.

Hi

I'm open again this thread because I heard that v2.5 bring back compatibility with supergrafx.

Is that true? Did someone test it?
