Supergrafx vs Everdrive freezing in Daimakaimura

[hyrulebr]

Hi!

I went in some trouble to get Daimakaimura running in a Supergrafx using Everdrive.

The video frozen after a few minutes (sometimes seconds). See pics and a video.



See the black bars near the sprite?





Screens frozen and goes bw. Sound a buzz. (also see video below)

Sometimes I heard a buzz other times the music continues like a slower version (but with sound glitches).

I read something about bad dumps, but afaik it's only affect Aldynes and Mado King Granzort. I never heard someone complaining about Daimakaimura.

I leave Aldynes running for hours without problem. Mado King Granzort I have some glitches in sprites and backgrounds but I think this a real bad dump problem. Battle Ace both original and using everdrive works fine.

I've already open in and inspect for a crack or something. I found nothing...

Tried 5 differents sources for Daimakaimura. Same result (or same dump).

What you think it could be? Is everdrive, the dump or the SGX?

Thanks

Does the SuperGrafx have a region mod or any other mods?

Have you tried switching to PCE mode and then back, making sure that the switch is all the way into SuperGrafx mode?

[hyrulebr]

Yes, I did. Position 2 SGX games didn't work. Only on position 1 and I make sure it's all the way to position 1.

I think my sgx isn't modded but take some pictures of motherboard.






Thanks

Try cleaning the cart slot.  I wouldn't say this issue is common but some consoles just don't seem to like the 2.4 everdrive.

Hi

Thanks for the valuable information!

When I opened it to take a look in the motherboard I cleaned the with isopropyl alcohol. But now I will do a better job. Also I will try to get a better position of TED in the console.

Thanks

I think that my TED v1.? works on my SuperGrafx but my 2.2 does not.

I think that my TED v1.? works on my SuperGrafx but my 2.2 does not.

V 2.2 is too much thicker than V 1.X?

Reading again the Everdrive forum thread I searched for information about this but didn't find anything:

Today I had it tested with real SGX hu-cards as well as roms flashed via a 39LF040 cart, and they play flawlessly.

What is it? Something like a repro hu-card?

My SGX was finicky with the ED as well(1.xver), not a constant thing but every one in a while it would have a fart...

Might be a power supply issue. I've run TED v 1.1 on my SGX for as long as the card has come out, without problems. But I'm also using a different power supply (the stock one died years back).

 I did recently have an issue with my SGX and Arcade card (obviously not TED card), and I found that I had to clean the connectors on the console to get it to work without glitches. Though my definition of "cleaning", was inserting/un-inserting the card rapidly about 20 times  - real fast.

Im using a original power supply. Pad113 if I'm no wrong.

I will try your technic with care because the contact is very tigh.

My tip for cleaning the HuCard slot is to get some of these.

Pull it tight against an old credit card or one you don't care about. Put rubbing alcohol on the end that will be pushed into the slot and then just push it in and out a couple of times.

I would even look for cracks in the board if possible only because as stuff heats up... it expands, you could have an issue elsewhere in there someone along one of the traces as the board gets warm.

Do any other games have this issue at all?

[Bonknuts]

Well, I brought up power supply issue because the TED does draw more power than a stock hucard, plus the power to devices on the hucard port is a little stingy. It's not that the stock supplies don't work (unless you're using a SuperCDROM addon with the SGX, then it needs either something with more amps or run two power supplies), but they do "fade" over time. And by fade, I mean don't deliver the correct output rather than simply not working (I've seen this for quite a few systems over the years - recently it was thee problem with a friends SegaCD setup; model 1). Just something to keep in mind, is all.

Next week I will leave it to my technican to check it out and if everything is fine, install a RGB mod.

He also have a SGX and can both test with his power supply or "make" one to just test. I will ask him to clear the contacts as well.

I keep you guys informed.

Thanks!

Hi,

Tried with a PAD 124 (Duo) power supply and with a Sega CD ps (both using a wire and a spare tip inverting the negative and postive). Same frozen.

I also tried to connect and disconect the TED to clear contacts but nothing until now. I will open it and tried a more complete cleareance.
