USB Stick STM32 (Gotek) HxC Floppy Emulator Firmware v3.1.60.5a -> v3.3.1.2a cumulative changelog:

• Fix multi-screens support (OSD + 7 segments screens)
• New Major feature !!! : On screen display support (OSD overlay)
• The HxC firmware for Gotek now support the On Screen Display !
• You can now select images and see the drive status on the machine’s screen without any additional software or LCD/OLED !
• No need to make holes in the machine case anymore ;).
• Picture: https://hxc2001.com/download/floppy_drive_emulator/HxCGotek_OSDAmiga1.jpg
• You only need 2 wires and a resistor to connect the Gotek to the machine’s video signals :
• One wire is used for the CSYNC video signal (Composite Sync), the other wire for the red, green (prefered) or blue signal.
• One resistor must be put in serie on the color signal between the Gotek and the machine.
• You can use a value between 220 and 470 ohms for this resistor. A potentiometer can be also used to tune the OSD brightness/contrast.
• This was currently tested on Amiga 500, Atari STE and Amstrad CPC 6128 machines, but should work with any machines having a composite sync signal.
• HxC Firmware for Gotek OSD wiring:
• Gotek wiring:
  • OSD Video out : Gotek U8 Pin 5 (PB15)
  • OSD Video CSYNC in : Gotek “JTCK-SWCLK” pin (PA14)
  • Picture: https://hxc2001.com/download/floppy_drive_emulator/HxCGotek_OSD_Mod.jpg
• Amiga 500:

• Power supply voltage measurement:
  • You can now see/read the power supply voltage incoming to the floppy emulator.
  • This feature is quite useful to check the machine power supply state/working condition.
  • If you want to use this feature you must add this voltage divider to measure
  • the power supply on the JC jumper input :
  • VSS/GND|—| 1Ko Resistor |–(JC pin)–| 4.7Ko Resistor |—< 5V Power Supply input.
  • ( See https://hxc2001.com/download/floppy_drive_emulator/HxCGotek_voltage_system_monitor.jpg )
  • Notes:
  • Use +/-1% Resistors if possible.
  • This voltage divider support up to 18V.
  • Use the embedded menu to access the system monitor :
  • Press both buttons to enter the menu. Choose “System Monitor” or “E  ” if you have the original 7 segments display.
  • “Temperature” menu renamed “System Monitor”.
• On-die STM32 temperature sensor support : You can get the current CPU core temperature from the embedded menu :
• press both buttons to enter the menu. Choose “temperature” or “E  ” if you have the original 7 segments display.
• Blackberry trackball : Sensitivity reduced/better usability.
• External/Additional select button support :  Behavioral fix -> remove glitch-like effect when selecting images.
• Fix the short and long read emulation pipeline buffer size options (custom fw web page).
• HFEv3 : Weakbits support added.
• Fix the files extensions display option : you can now also hide the file name extensions in selector/indexed mode.
• New major feature ! : Auto mount USB stick folder to a FAT/DOS compatible virtual floppy !
• This feature allows you to directly put your files in a stick’s folder and mount this folder as a FAT/DOS floppy disk !
• You can use it with any machine compatible with the FAT file system (PC, Atari ST, lots of keyboards/samplers and CNC machines…).
• To use this feature, copy an empty/preformatted DOS IMG image to the stick path “/mount/emptyfat.img”
• This image can be a 720KB or 1.44MB blank DOS image or any other FAT compatible blank image.
• You can use the HxC Floppy Emulator software Disk Browser to create it or take the ones present in the firmware archive.
• Once you select a “mount source” folder on the emulator, the emptyfat.img file is duplicated to a “MOUNTED.IMG” file.
• Then all files/subfolders present into the selected folder are added into this duplicated image.
• (Note : the emptyfat.img remains untouched).
• Your “mount sources” / root folders should have the extension “.mnt” to be mounted by the emulator :
• example : “myvirtualdisk.mnt”
• This new feature can be used with the “normal”/direct browsing (oled/lcd screen usage) and indexed modes.
• For the indexed mode just put the DSKAXXXX prefix in the mount point folder name.
• example : “DSKA0000_MyMidiFiles.mnt”
• Please note that the image duplication and files copy operations can take some seconds.
• I will try to optimize/speedup the mount operations in the next releases.
• Let me know if you have any problems or any suggestions/questions/comments on the HxC forum or by email.
• FAT 12/16/32 layer write support enhanced to create entries (files & folders) and allocate clusters.

This is only a little part of the changelog. The original one is very long and you can read it here. (instruction manual here)

ARM2SID SIDs (until 3) & SFX Sound Expander (OPL FM synthesis) emulator.

Nobomi still amazes us with the ARM2SID a new TWO or THREE SIDs and SFX Sound Expander (OPL FM synthesis) “emulator”.

The socket size of the ARMSID is DIP28 and is absolutely the same of the original chip and therefore fits perfectly in all situations.

The audio quality is really good for both; SFX Sound Expander (OPL FM) and the SID emulation.

It also possible add a second socket as the second SID if you have Stereo/U64/Reloaded adapter or connect wires directly to your Commodore computer.

• A next logical step after succesful ARMSID. ARM2SID is based on the same blocks as ARMSID but one step more advanced blocks.
• Thanks to them, it added the possibility of emulating up to two additional chips and / or FM synthesis with OPL2.
• Like ARMSID, ARM2SID is a replacement for the MOS6581 and MOS8580 circuits used in Commodore C64/C128. It comes again in a minimalist form, but it can do a lot more.
• It can replace up to 3 chips at the same time, it can also emulate SFX sound expander as well as the newer FM-YAM clone.
• SIDs emulation itself is the same as with ARMSID, so emulation features can be read on its page.
• Up to 12 channels music (two or three SIDs or FM or one SID and FM)!
• Works with all C64 and C128 boards (please read manual)
• Stereo in any combination of SID 6581 or 8580 models.
• Automatic fall-back to dual mono if second SID is not used.
• Configuration and upgrades by software utility in C64/C128.

More information can be found on the Nobomi website or RETROCOMP.cz

I was very curious what ZeroPaige has written in the description of the Super Mario Bros 64 game, the game on the C64 DTV use the Turbo mode.

I have tried the game on my upgraded C64 DTV and in fact is much more fluid, i would say perfect except for a few graphics glitches.

Below what ZeroPaige writes about the Turbo mode:

Since the NES-processor is clocked (roughly 70%) faster than a stock C64 there can be slowdowns during gameplay. A pixel indicates this on the time-watch graphics in the status bar.

This port will try to detect and use any kind of turbo functionality, such as:

• Commodore 128 (2 MHz in the border)
• C64 DTV
• Schnedler Systems Turbo Master CPU (untested)
• Swisscomp Turbo Processor (untested)
• Rossmoeller Flash 8 (untested)
• CMD SuperCPU Accelerator (untested)

USB Stick STM32 (Gotek) HxC Floppy Emulator Firmware v3.1.38.2a -> v3.1.60.5a cumulative changelog:

• GeneralMusic S2/S3 : Undocummented floppy format support added + *.gem file extension support.
• Non-gated interface : Ignore the floppy selection line for the head step + Some fixes.
• Motor-ON signal support to emulate properly the “READY” and “INDEX” signals.
• OLED : SSD1305 2.23″ 128×32 OLED screen support added.
• Internal enhancements. (WIP)
• New direct raw format support : Yamaha QX3 format (*.IMG,*.DSK)
• 7 segments screen menu : Add missing system family entries :  
  • 15 = Robox RC9400
  • 16 = Kawai
  • 17 = Yamaha QX3
  • 18 = User defined format
  • Gotek I/O Lines Diagnostic/Test mode Since this hardware is quite sensitive to ESD and other electrical issues, the floppy lines can be easily damaged.
  • This new mode allows you to test/check all Gotek’s Input/Output lines with a simple wire.
  • The test must be run with floppy ribbon disconnected from the machine.
  • Once enabled/flashed with the diagnostic firmware, all outputs will toggle every 2 seconds.
  • All inputs states are displayed on the screen.
• Input lines test method :
  • The default input states should be High (1), so to test an input line you have just to connect it to the ground/vss. On the floppy port you just need a jumper to make a contact between the line and the ground.
  • Once the jumper is placed between the line pin and the ground/vss pin the corresping input state should turn to Low (0).
• Output lines test method :
  • All outputs are toggling every 2 seconds during the test.
  • (Note : A 1 ms pulse is sent to the JB output at each toggle to test the buzzer ouput)
  • Connect the output line to test to one input line (use a tested input by the above method) with a simple wire.
  • If the corresponding input status is toggling with the outputs line, then this means that the output line/driver is working properly.
• LCD / OLED / 7 segments screens output/input status definition :
  • LCD/OLED input lines status format : “IN:123456 789AB”
