boye Posted August 27, 2020 Share Posted August 27, 2020 Hi all, My Twin Famicom has decided not to read disks after I put in a castlevania disk, and now it just throws Error 22 after a bit of loading. This only started when my Castlevania disk failed to read, and Zelda is my only other disk. Quote Link to comment Share on other sites More sharing options...
Magmavision2000 Posted August 27, 2020 Share Posted August 27, 2020 You might want to try replacing the belt. Those things are known to break over the years. Quote Link to comment Share on other sites More sharing options...
boye Posted August 27, 2020 Author Share Posted August 27, 2020 The belt works just fine. It even was replaced a few months ago. Quote Link to comment Share on other sites More sharing options...
phoenixdownita Posted August 27, 2020 Share Posted August 27, 2020 It is possible the head miscalibrated: https://www.famicomdisksystem.com/tutorials/fds-repair-mod/belt-replacement-adjustment/ Side note: on my Twin Famicom there was the copy protection PCB that I simply bypassed by connecting the main PCB directly to the floppy, it was not in all Twin and some had it integrated (so it can't be removed). Not saying it is the cause of your woes but in case. It looks like an extra small board that sits in between the floppy and the power PCB.

boye Posted August 27, 2020 Author Share Posted August 27, 2020 How could a disk cause that issue? Quote Link to comment Share on other sites More sharing options...
ApolloBoy Posted August 27, 2020 Share Posted August 27, 2020 Did you try cleaning the drive head? Quote Link to comment Share on other sites More sharing options...
boye Posted August 28, 2020 Author Share Posted August 28, 2020 I'm gonna try that and see if it makes a difference. Quote Link to comment Share on other sites More sharing options...
CatPix Posted August 28, 2020 Share Posted August 28, 2020 (edited) Retuning might be in order, as well as checking your belt. I was like you recently, getting error 22 all over, and thoguh "Hmmm my disk belt is not even 2 years old, it can't be that". When I opened my Twin, the belt snapped in half. Discussing with people selling belts, there are alot of low quality belts on the market, and also, when reproduction was much more rare and expensive, sellers would hold of belt stocks for years. That "brand new" belt you got in your Twin Famicom might actually have been manufactured 10 years ago...

boye Posted August 28, 2020 Author Share Posted August 28, 2020 Just checked the belt and it looks and feels fine. It is in one piece. Quote Link to comment Share on other sites More sharing options...
