Blue Disk Issues - Error 27

[MalditoComm]

Hey everyone,

My first post on the board as I couldn't quite find another post about this. Just got my FDS working after swapping the disk drive I rebelted to a new system (damaged power supply I don't really want to fix).

Only F1 Race (Blue Disk) would work. However, after tweaking the drive I managed to get all my yellow disks working. I tried F1 Race again but I ran into an issue where when flipping to side B, it gives an Err 27 screen that is super corrupted (so I am only 90% sure its Err 27). Every menu option on Side A works just fine, it's just the flip to side B that causes a problem. This does not occur with Zelda, Zelda II, Kid Icarus, or Dirty Pair.

The blue disks aren't in any way special internally. This probably just means you're still very slightly out of alignment, or the disk itself is bad. Try to see if lowering or increasing the drive speed slightly doesn't make it load.
