Hi all, I've Googled and Googled this and can't seem to find any consistent answers. I just bought an FDS off ebay and it works for the most part. However, I have a few games for which it gives error 27, and one gives error 23. I've read about adjusting the motor, the drive head, etc. etc. and really am quite confused by the deluge of information. Is it more likely a problem with the discs themselves, or should I really adjust something, and if so, what exactly do I adjust?
By the way, the games that give the error messages appear to be official, Nintendo-licensed discs. I've also cleaned the metal reader head with rubbing alcohol, though it wasn't very dirty.
