Since i don't like to release a new firmware with so many changes, i prefer to put it here as an alpha version.
Since the last beta here are the updates :
- New buttons behaviour and better debouncing filter. Navigation user-experience should be better now.
- Disk Eject function : Press both buttons to eject the disk. Working in indexed, autoboot mode, and normal mode.
- "Eject at power up" option added.
- Support up to 999 Images in autoboot mode (with the File selector) (Use the new CFG file format and selector to "activate" this feature)
- LCD : Display refresh improvements.
- New CFG file format : Some new flags and no more slots/disk drive limitation.
- Some critical parts rewritten in assembly. Huge code speed improvement -> Better HD density reliability. ED density to be tested
![Wink ;)](./images/smilies/icon_wink.gif)
- Advanced USB mass storage cache implemented to improve read/write reliability.
(Btw : Now when track size can be stored into the SRAM, the emulator will not read forever the data from the stick but use the cached data instead).
And :
- The File selector is now available under Windows and Linux ! : You can now edit the list from a PC !. (Compatible with all SD/USB HxC drives !)
To launch it : HXCFEMNG [SD/USB drive letter:]
A Linux version is also available.
See the readme file for more details.
This is a new solution for all others machines without file selector available.
TO BE DONE :
- Finish the IMG/ST file write support. Most part is there, but still a bug to fix. EDIT : Done !
EDIT : 4 July 2017, new version :
- Huge RAW (*.ADF/*.ST/*.IMG) Write performance enhancement (Write 2 tracks at once !)
- RAW *.IMG files can be used in indexed mode : Name the files DSKA0000.IMG,DSKA0001.IMG,DSKA0002.IMG,...
- Small (for the moment) HFE write performance enhancement.
- "Autoboot.hfe not found" message added.
EDIT : 7 July 2017, new version :
- 7 segments "dots" glitch fixed.
- 128 & 256 bytes sectors support added in raw mode.
- FM : Work in progress (Read working, Write to be done).
EDIT : 10 July 2017, new version :
- Raw file FM Read & Write support ready !
- Some more write speed optimization.
EDIT : 4 August 2017, new version :
- New File format support (WIP) : HFEv3. Can now support copy protected images converted from IPF and others similar formats !
Variable bitrate supported (CopyLock & SpeedLock). Weak/Flakey bits support to be added !
- Fix IPF support for these games: Jim Power, Z-Out,Xenon 2,Ghosts'n Goblins,Rainbow Islands,B.A.T II and probably some others !
- Slot number printed on the second line during slot search with an LCD.
- XCopy write issue fixed.
- Sound buzzer output on the "JB" jumper position. You can connect a piezo or a magnetic buzzer (transistor needed for the magnetic version).
The sound output can be disabled or enabled into the selector settings.
(Note : Please remove these old sound mod using directly the step signal, they are producing reliability problems...)
- Mixed track format/density write support fixed (To be tested!).
Selector software :
- New Bootblock for the Amiga version : The file selector is now "trackloaded" and start faster.
- Speed up the sub-directory change/browsing.
- Can start an image from the slot page with the F7 key.
- The File selector is now available under Windows and Linux ! : You can now edit the list from a PC !. (Compatible with all SD/USB HxC drives !)
To launch it : HXCFEMNG -disk:[SD/USB drive letter:]
See the selector readme file for more details.
This is a new selection solution for all others machines without native file selector available.
- Linux/Windows version : You can now import from txt file / export to txt file / auto populate / check / fix and clear your slots configuration.
Very useful for fast populating and compilations duplication
![Wink ;)](./images/smilies/icon_wink.gif)
- Windows version : Fix big size (>8GB) usb stick/sd access issue.
- populateslots option : autoboot.hfe filtered.
07 aug 2017:

EDIT : 8 August 2017, new version :
- LCD Display : Refresh rate adjusted and I2C dead lock issue fixed.
- Normal / direct browsing mode :
Auto selecting the current image or subfolder if you don't
press the buttons during than 4 seconds. If needed, the file name
scroll during the delay time.
This modification make the additional select button optional.
Of course the LCD still needed for this mode.
- Indexed/selector mode :
Delay added before selecting the image. Browsing through the slots
is smoother. If needed, the file name scroll during the delay time.
- 7 segments display :
New error/message codes :
"FAt" : Fat init error.
"NFL" : No file. Empty stick ?
"CFG" : Config file not found !
"cFG" : Bad config file !
"Nor" : Warning -> in Normal/Direct browsing mode. You should use a LCD screen.
"AUt" : Autoboot.hfe not found.
"Err" : File image error !
"Ldr" : Into the bootloader.
- Config file save : Before writing to the disk, check that this is really needed.
(Parameters change check)

The drive can now "capture" a new floppy write while it is writing
previous write(s) to the stick.
