FDS question

[Rotinaj]

I have a FDS and it has a new belt and it works fine but one of the games i have gives me err.22 when i switch it to side B. Clearly it's some wrong with the disk, I'm just wondering if anyone knows what it is and if there is a way to fix it.

Either get a new copy that works or you'll have to try to rewrite the disk, though I've never dealt with this myself. The idea is to take control of the system and instruct the FDS to write data to the disk.

If you want to go that route, here's some info at Famicom World. If I recall only certain models of the FDS can be adapted for this modification.

Here is some good info for FDS error code diagnostics in general: http://www.famicomworld.com/forum/in...p?topic=7142.0
