You can now use the emulator without this file on the SDCard. Note 1: Without this file the emulator is in "normal mode" / direct browsing mode. Note 2: Without this file the last selected file position is not saved. Reminder : You can setup the emulator with the embedded menu without the need of any configuration file : To access this menu, remove the SDCard and press the select button. Once in the menu you can choose the option you want to change. - System and hidden files and folders on the SDCard are now invisible on the emulator. You shouldn't be annoyed anymore by non-HxC folders and files on the emulator. :) - Image auto-load disabled when the user press the left or right button : -> Faster SDCard browsing, More consistent browsing behavior. (On this point if you prefer the old/previous behavior, don't hesitate to contact me to let me know : hxc2001 at hxc2001.com) 5 January 2020: Firmware SD HxCFloppyEmulator v1.8.6.20 (beta) - OLED screen Winstar WEH001602A / WS0010 based OLED screens support added. 1 August 2019: Firmware SD HxCFloppyEmulator v1.8.6.19 (beta) - Fix -> HFE internal name change feature : The new name is used right after the renaming. 10 April 2019: Firmware SD HxCFloppyEmulator v1.8.6.18 (beta) - Reenable format support (fix v1.8.6.17 configuration regression). 31 March 2019: Firmware SD HxCFloppyEmulator v1.8.6.17 (beta) - File selector mode : Image Ejected at power-up option supported. - File selector mode : Selected Slot number sound count disabled when the emulator has a screen. 29 September 2013: Firmware SD HxCFloppyEmulator v1.8.2.40 - Index signal behavior corrected while the host system attempt to format a drive without image loaded. 06 September 2013: Firmware SD HxCFloppyEmulator v1.8.2.36 - Write Support : Write issue with VIA VT82C686A chipset based motherboard corrected. 20 August 2013: Firmware SD HxCFloppyEmulator v1.8.2.30 - SDCard Support : Delay added right after any command (PNY microSD support). - Watchdog delay changed to 16s. - Brownout reset setting changed. 18 August 2013: Firmware SD HxCFloppyEmulator v1.8.2.26 - Device init : the whole internal memory is now cleared at power-up. 13 August 2013: Firmware SD HxCFloppyEmulator v1.8.2.24 ------------------------------------ ---- Major Update ! ---- ------------------------------------ -> Write Support completely redesigned / reworked : - Low level track format support added ! : The host computer/machine can now do low level format of the disk images ! By this way the floppy disk image can be formatted with the right disk layout from the machine. All the tracks parameters used by the machine (sector size, interleave/skew, gap, format value, index mark...) will be written to the virtual disk tracks ! By this way the user have just to copy some blank HFE images to the SDCard, and format them with the host machine as with a real floppy disk to make them usable. Some blank disk images with various density will be available for download on the HxC2001 website. - SD/DD/HD sector write support : all sector sizes are now supported ! : 128B, 256B, 512B, 1024B, 2048B, 4096B, 8192B... - Unaligned track/sector write is now possible : Sectors of host formatted images and images imported from stream files (Kryoflux...) can now be written ! -> SD Access enhanced : Better handling, track buffer size increased. -> Floppy interface mode enhanced : New Pin02/Pin34 Custom settings. -> Indexed files mode added : File naming convention : DSKXYYYY.HFE with X=A for drive A & X=B for drive B and YYYY=index number. Once the SDCard is in the emulator, the "next" button allows you to select the next file image. Once the last file is reached, the index is set to 0 (DSKA0000.HFE/DSKB0000.HFE). To jump to the first image (DSKA0000.HFE/DSKB0000.HFE) from any index position, you have just to push the "next" button more than one second. To use it, this mode must be enabled into the HXCSDFE.CFG file. This mode was added to offer a compatibility with the Slim version of the HxC Floppy Emulator (no lcd and only one button). -> SDCard file system support enhanced : Now support FAT 12, FAT 16 & FAT 32 formatted SDCard ! Any SDCard size are now supported ! -> Direct access mode : New function to get and set easily the current index number in "file selector" & indexed mode. -> Low level LCD routines improved, file name scrolling behaviour changed : pause of ~1s before starting the scrolling. -> Embedded files browser : Files are now filtered : Only HFE files & folders are shown and can be selected. -> Lots of internal code optimizations/improvements and corrections... ------------------------------------------------------------------------------------------------------------------------- -- Important !! : This version is not compatible with the old Revision B boards (2010 version) -- The add-on SRAM chip is now needed for all write support ! (for more details please see the release 22/08/2010 below) ------------------------------------------------------------------------------------------------------------------------- 18 November 2012: Firmware SD HxCFloppyEmulator v1.7.2.7 - Amiga track step settle time corrected. 28 October 2012: Firmware SD HxCFloppyEmulator v1.7.2.0 - Microchip PIC18F4620 Rev.

DataMark supported : 0xFB,0xF8 (deleted data mark), 0xFA,0xF9. HFE file format enhanced : Track 0 Side 0 & Track 0 Side 1 track write mode can be different from the others tracks. - New track seek algorithm : Faster track seek/settle time -> Faster Loading time ! - Flip disk function : the disk image can now be flipped (reverse side 0<->side 1). - Bad track number at power up corrected (E-mu Emulator I/II, SP1200, Linn/Forat 9000...) - Experimental "Rev2" HFE support : Correct some issue with some Amiga games/demos. - Lots of internal code optimizations... 10/04/2011: Firmware SD HxCFloppyEmulator v1.6.0.0 - File browser : The file browser now jump to the start/end of the file list once you reached its end/start. - Direct access mode : Speed optimization for the Hard Disk Emulation mode ;-) : ->Faster read and write Access ->Dynamic sector number during read/writing (Hard disk emulation driver available soon on Atari ST computers ;-) ) Note: The file selector software must be updated! - HFE file renaming Function : ->The HFE file can now be renamed. To do this just select an HFE file and press the select button during 1 second. Then In the function menu choose "Rename Img file". Note: The file name on the sdcard isn't directly changed by this function but the new name is changed into the HFE file. - New boot/power up mode : ->New Option to force loading STARTUPA.HFE at power up into the drive A. ->New Option to force loading STARTUPB.HFE at power up into the drive B. - Autoboot/file selector program boot mode enhanced : ->New Option to Force loading AUTOBOOT.HFE at power up (don't load the last selection at power up) ->New Option to choose the next slot when inserting the SDCard. With this feature, the LCD screen and buttons are optional because the SDCard can be used like a true floppy disk: eject it and reinsert it to choose the next Floppy. - Write support : No more glitch on the read data line during writing (Correct write problem on some FDC). Write gate management bug corrected in 500Kbits/s MFM mode. (765A FDC write bug). - Various bugs corrected and code enhancement... 30/01/2011: Firmware SD HxCFloppyEmulator v1.5.1.0 - Direct access mode : Bad Write mode corrected. - Display: Negative Track position bug corrected. - Internal : write mode selection code clean up. 25/01/2011: Firmware SD HxCFloppyEmulator v1.5.0.0 - SDcard : Init frequency corrected - SDcard : Multi sector read & Write access added. -> SDCard access time improved (Slow sdcard issues corrected) - Some important parts of the floppy write support fully rewritten : Important codes improvement (speed & size) -> MFM ISO Sector write support speed & code size improvement. -> Amiga write support speed & code size improvement .

Without this great help, releasing this new feature wouldn't be possible. - Two floppy drive emulation improvement/bug corrected -> The two virtual floppy disk drive can have different bitrate now. (example : an 1.44MB floppy disk in the first disk drive and a 720KB in the second disk drive.) - SDCard HxC Floppy emulator settings (sound/blacklight...) are now stored into the eeprom and used at power up. At power up the last known settings are used. 07/11/2010: Firmware SD HxCFloppyEmulator v1.3.0.4 - Amiga : Change disk delay added. - Buzzer driving bug corrected. - "One button" mode feature added. - Double step support added. 26/09/2010: Firmware SD HxCFloppyEmulator v1.3.0.3 - Direct access mode : Write mode corrected (Amiga support). - Corrupted MFM flux bug corrected 05/09/2010: Firmware SD HxCFloppyEmulator v1.3.0.2 - Shugart & PC interface mode behavior corrected. 28/08/2010: Firmware SD HxCFloppyEmulator v1.3.0.1 - Amiga Write support : SRAM identification corrected. 22/08/2010: Firmware SD HxCFloppyEmulator v1.3.0.0 - Amiga Write support added : Note to the Revision B PCB owners : To activate this new features you need to add a Microchip 23K256 SPI SRAM chip and 4 resistors. The connection to do is : 23K256 pin 1 -> 220ohms resistor -> PIC18F4620 pin 22 23K256 pin 5 -> 220ohms resistor -> PIC18F4620 pin 27 23K256 pin 6 -> 220ohms resistor -> PIC18F4620 pin 28 23K256 pin 2 -> 220ohms resistor -> PIC18F4620 pin 29 23K256 pin 8 & 7 -> VCC3.3V (this voltage can be found at the capacitor under the sdcard connector or at the output of the regulator) 23K256 pin 4 -> GND 23K256 pin 3 -> Not connected.
