Famicom twin won't read copies.

I cannot get my sharp twin (early edition) to read games I've copied on my original disk system. I would love to know why. I was getting err.23 but I've just gotten err.27 and decided to goto the forums. There is a lot a lot about people having errors but in one post someone mentioned that the Twin Famicom has a lockout for copied games. Is this the issue? The Twin plays everything flawlessly that hasn't been copied. My Famicom disk play everything like a beast. The twin has been new belted and realignment done and I've never had any issue with it. I'd love to sort this out as the Twin has such a clear picture compared to my fuzzy jailbar Famicom.

Thanks people's.

Presumably the calibration on the FDS and the Twin are not the same.
Writing copies is just way less forgiving on that front, and you can have your exact situation if both the drives aren't matched quite exactly.

Ok thanks. After the battle with the twin famicom drive calibration when i got it, i think i'll just leave it alone and accept that it only like to play the originals. Thanks for responding

You can always plug in the standalone FDS into the Twin Famicom and get a clear picture that way.

The reason homewritten games doesn't work seems to be due to improper calibration. The usual trial-and-error method suggested everywhere is bound not to work as you never know how close you are to the factory calibration, which is why only select games work. Any disks written on the drive will not work on any other drive.

Factory calibration supposedly requires using an oscilloscope.
