Hi,

I bought a SuperFlash kit from GBAX.com and received it today. I first tested in a JAP SFC, as I'd seen on this forum that the flash carts come preloaded with a game. I got no response, so I presumed that there was no game present. I then loaded on Seiken Densetsu 3e, also no response. I've since tried the cart with between 1 and 4 games (various ROMs and sizes), flashed using various versions of SuperFlash and the latest uCON64, and in 2 different JAP SFCs and a US SNES.

The most response I've ever got from it has been a corrupted purple screen, that flickers randomly for a few seconds then goes blank.

I've always used the T-connector with a US game on the back (tried the switch in both positions, although mostly down obviously ). The T-Connector seems to work fine as I've tried it with a real US game on both the top and back, and the game on top runs. I can flash ROMs onto the cart fine, and also read ROMs of my own original carts.

Has anyone else encountered anything like this and been able to fix it, or am I going to have to get a replacement kit?

Are you sure that your Superflash doesn't have a PAL CIC chip installed?

Once you write a game to the cart, can you read back the game and verify the image is the same as the one you wrote? If you can do this you should be in pretty good shape.

Even with no CIC on the Super Flash you should be able to use the T-Connector with the switch in the right position. IIRC the Super Flash has to be in the Top of the T connector and the SNES game cart in the side. The only other thing I can think of is to make sure you're inserting everything with the correct orientation. Check this, but IIRC it goes: T-connector FRONT facing the front of the SNES, Super Flash into the top of the T-connector with the Front label on PCB facing to the front of the SNES, SNES game cart into the T-Connector with the front game label facing up.

There's definitely no CIC chip installed on the SuperFlash. I can tell the console recognises the CIC on the US cart, as if I flick the switch on the T connector up, or put the SuperFlash straight into the console I get a completely blank screen, no signal at all from the console. When it's all set up properly, my TV is obviously getting a signal from the console as it displays a slightly grey picture, and as I said before, occaisonally I get a corrupted purple screen.

I haven't been able to read a game back off the cart, the software doesn't seem to allow this. The "Backup card ROM" button is only active when an original cart is in the programmer, it's greyed out when the SuperFlash is inserted, is this wrong?

I've tried reading back the contents of the SuperFlash with uCON64, but this always produces a 64Mbit image, regardless of what games I wrote to it.

I tried writing the whole 64Mbits of the cart (Using an image created with uCON64 out of the menu, Chrono Trigger and Killer Instinct) and then reading it off again. The MD5 sums of the the 2 images do not match, and the data in them looks completely different when viewed in a hex editor.

Does this indicate that there's something wrong with the flash cart, or could it be an issue with uCON64? It did truncate Killer Instinct when creating the multi game image, presumably because adding the menu takes it slightly over 64Mb.

This also did not work in a SNES, produced a garbled screen (image below). Interestingly, whenever I get one of these garbled screens, I can't reliably reproduce it. If I turn the console off or reset it, I usually just get a blank screen again.
