Famicom disk System Error 27

Lol, taking another look at that mod, the person did an absolutely terrible job. Looks like they found a way to make it far simpler, though...for better or worse, who knows.

What's the black thing the TGD is sitting on?

It is a H.E.S. Unidapter. For NTSC and PAL NES plus FC. It's the adapter I use to plug all things FDS into the NES. Great adapter actually!

Actually none of the disks I have work when the TGD6+ is connected. Neither official Nintendo disks nor bootlegged disks. I don't get any FDS-error, the FDS gets past that and loads the FDS-copyright screen. But after that all I get is a black screen. Any thoughts? I noticed there was an uncovered eprom inside the TGD, maybe it's dead? Thoughts anyone?

I've seen the copyright then black screen anomaly before, but not with a TGD6...I dunno, try hitting reset? You probably did that, though. So not even the Nintendo disks worked? All I can say is try using FDSLoadr to load an image directly to the RAM adapter. If it still doesn't work, your dive may still need some finer tuning. It is extraordinarily unlikely the EEPROM has gone bad.

Yeah, um might take a while before I have the time to take the FDSloader project upon me.. Both lazy and busy at the moment. Sometime during this fall/winter I'll do it.. First of all I feel I should go over all the solderings, maybe improve a little and solder the one wire that fell of back in place.

As for the last 3 disks, they might just be crap.

However, here's a little trick...sometimes pirate disks, and especially pirate programs refuse to work on anything but new or like-new drives. If you drive seems to be loading most things fine, sometimes a little extra pressure on the felt thingy on a spring above the drive tray helps the head read the disk surface better. Unever pressure like a finger is a no-no, though. I've heard rumors some folks fastening a dime or two, or even a quarter there to give it a bit more pressure.

I think I read that document..I'll try that and also I'll keep finetuning and hopefully I might get them to work. Thanks for all the help Rob! I've learned alot!

No need to thank me. Any time, dude.

And that unidapter rules. I never heard of one of those. I'm getting one! Just in case CopyNes ever supports FDS dumping, it'll be a lot more useful than piggybacking three stupid adapters together.

Has anyone been able to access the calibration pages? it seems that whole site is down. I tried to load it with Internet archive, but it does not have pictures.
