Yamaha SY99 - Disk Not Ready

Post by gcampi »

Hello,
I have a problem with Gotek SFR1M44-U100LQD (OLED Display and Rotary encoder). Board is marked: SFRK30.AT4.35 (Artery chip).
Successfully flashed with HxC firmware - Latest release.

I'm not able to use the emulator; SY99 show 'Disk not Ready' on display everytime I try to access a floppy image.
Images can successfully selected with rotary encoder. The problem occurs with .hfe images and .img images.
Tested with two different connecion cables both bought (not self-made).
Following other posts, I've check multiple combinations for parameters with HxCFloppyEmulator.exe saving different HXCSDFE.CFG and different Jumper settings, but nothing change, always 'Disk not Ready' ...
During disk access, the track number on oled display changes fast and apparently random.
Images have been prepared with DiskImage 1.6 (Windows) using original SY99 floppy disks; converted in hfe format with HxCFloppyEmulator.exe.

Is there a kind of step by step guide or troubleshhoting guide for SY99 or sameone who kindly can help me ?

Many Thanks.
Gio.

Try to generate a firmware with the "Non gated mode" option set :
