Re: the USB thing you're not missing anything because it _did_ work simply and well unaltered - I bought the exact the drive you mentioned and used it in it's native firmware for a while, and I'd fire up a Windows VM to do the disk operations when needed. Then getting drives for the additional SY's I've collected over the last 2-3 years, unfortunately I found the firmwares in the additional GOTEK units from the same vendor were all over the place, there was no reliable way to get specific version of firmware in the drives - only one other of the total of 8 I bought worked as the original. Surfing the web indicated others had the same issue.
So that out of the box functionality was hit and miss -- the issue I had was without that particular firmware, formatting the USB stick in regular Windows resulted in the USB drive seeing it as a single 720K disk only recognizing the first folder. I had to use the Keytron disk software to set up the USB Stick. Became a PIA for me, so migrated to HxC which worked the same way as the Keytron software but was at least OSX compatible. The hassle was the cost and difficulty in flashing drives with HxC but I'd rather do that (once) than to keep waiting for launching a Windows VM to do 30 seconds of disk/file management.
I scored another "hit" with a new SFR1M44-FU-DL that came from China this week. It's functionality is ALMOST identical to that of other SFR1M44-FU-DL units I had bought in the past. Two things are different so far. The hidden dual-color LED that was inside the emulator initially and you had to drill a hole for it to become visible is not there anymore. No big deal, I have already located such a LED in the parts bin that I will solder in there.
The other change I noticed is in the firmware. In the past when I removed the USB drive to be able to select the folder I needed with the front buttons I would notice the 3 dots on the display light up. If the USB drive was put back they would turn off. Not anymore, they stay off no matter what. But the remaining functionality appears to be intact. The new unit replaced a floppy drive inside a Yamaha MDF3 I acquired recently and works fine.
I have a question for you and perhaps other members if they can answer it. Along with the emulator I ordered the I2C small OLED display thinking that I could perhaps try flashing the emulator to use the new display, even though the MDF3 does not need that functionality. Do you know if there is a way to copy the existing firmware on the emulator BEFORE any flashing is performed? The OLED display and USB-TTL programing cable are not here yet but that does not stop me from making plans.
Any advice/link on this matter would be appreciated. I have seen sites and videos on how to flash the emulator but nothing on how to copy the existing firmware that came from the factory.
