need help with current project. read

hi all.

let me start by saying i have three fds disk drives, 1- stock (3206), 1-half modified (3206), and 1-fully modified (7201).

my current project in my fds lab is to see if i can write a fds disk that will play in all three of my drives. becoming tired of using same drive to write/play games on. it would be nice to write game using fully modified drive, and play using any of the three. my current research is on editing the .fds file itself to load no matter what drive its in. so far....... i have been able to get a disk to play in two of my three drives, but not all three drives.   i need help from others who may be more knowledgeable than me, or people who wanna " help on the research". if you wanna get involved in an awesome .fds lab experiment, here's your chance!!!.

BY THE WAY: FOR THOSE WHO'S GONNA SAY " DISK ARE ONLY PLAYABLE IN THE DRIVE THAT WROTE IT"...... B.S!!!!!!. ANY SITE THAT SELLS "COPIES OF FDS DISK" WORK IN ANY DRIVE, SO I KNOW ITS POSSIBLE. JUST HAVEN'T FIGURED IT OUT COMPLETELY YET, BUT I WILL. VERY CLOSE NOW !!!!!

TIL THEN FAMICOM FANS!

Okay, first off, it's not 100% BS. The devil's in the details, like most things.

Here's why: FDS disks are written like a record, in a spiral. The beginning of the file (disk data) is contingent on where the donut on the spindle that rotates the disk is aligned in relation to the head.  If the donut placement in your three drives isn't close enough between all of them, you may or may not be able to read disks written on one drive from drive to drive.  If you get them all set up the same, they should all read disks written between them, provided the disks are written after all the drives are aligned to match.  If you can get a disk to read between all 3 drives, that's why. It heavily depends where the drive starts to write the disk data. The alignment position is messed up when the drive belts are changed, which is why you'll find there is such variance from drive to drive.
