Sega System 24 Floppy Issue

[Lastsix]

I am repairing a Gain Ground cabinet and am having trouble getting the floppy to work.

The game will boot and sit on the loading screen; but the mainboard works and passes all self-tests.
I have several floppy drives and some of them will cause a drive not ready error and the others will sit and do nothing.
I checked the FD1094 on a programmer and it seems to be ok.
The board had a (non-original) floppy with it and I made an additional floppy following this guide,
https://techdocs.exodusemulator.com/Arcade/SegaSystem24/CopyingDisks.html

There is very little information on the internet about the system 24 and am unsure if this is a drive issue, a floppy issue, or rom issue.
At this point should I just buy a gotek?

Considering a Gotek is $20-$30, I would just buy one and see if it works.

for going with an FDD Emulator I have a guide here: https://www.arcade-projects.com/threads/oled-selector-for-sega-system-24-fdd.28866/

I will buy a Gotek and try it.

Are the decrypted system 24 images available on the internet somewhere?

You can get an io-test firmware for the gotek as well, that helps to see if the fdc signals are arriving at the floppy and the other way around: https://github.com/keirf/flashfloppy/wiki/Testing-IO-Pins

Might be that you're on the right track checking the floppy drives and FD1094. If you’re still stuck, a Gotek might be a solid solution, especially since it’s more reliable and easier to troubleshoot than dealing with old floppies. Worth a shot if you’re hitting a wall!

It lives.

I had a helluva time trying to find a mame image that would work and convert it for the gotek.
Using the default ribbon that came with the board will give a ribbon error on the gotek for some reason. I am using the gotek with a ribbon from a pc for now.
Old drive still won't work.

Thanks for the tip on drive modification.

There are two genuine types of FDDs in SYSTEM24.
Let us assume that they are A and B.
The FDD copied on A will not work on B.
Conversely, an FDD copied with B will not work with A.
An error occurs when reading.

The problem seems to be solved, but please keep this in mind as information
