Turbo Chameleon 64 is an extremely user-friendly cartridge that can be used without opening the computer. It is just plugged to the expansion port of the C64.
The Turbo Chameleon 64 cartridge can also be operated as a stand-alone unit (since it’s basically an FPGA computer like the C-One or the Minimig in a C64 cartridge case), replacing the computer, the floppy drive and the heavy power supply.
When used as a stand-alone unit, a USB power adapter or active USB hub can be used as a power source.
Changelog:
- New VGA controller with new modes and VIC-II sync.
- Tripple buffering mode added for properly displaying IFLI pictures.
- Scale-2x video scaling algorithm added.
- Scanline emulation added.
- In cartridge mode real CIAs registers and interrupts are used (allows use of a modem).
- In cartridge mode real VIC-II registers and interrupts are used (allows use of a lightpen).
- Fixed I/O assignments for FPGA (lower power use).
- Lowlevel SD-card functions now use multiple block reads if possible, which increases linear reading speed by about 40 to 50% (most noticeable on large files, such as REU images)
- BUGFIX: fixed error handling and timeouts of the IEC routines, which makes all related operations more robust.
- BUGFIX: added missing timeouts to SD-card functions.
- Joystick port 1 now also works for navigating the menus.
- BUGFIX: on some C64s pressing shift would result in phantom keypresses (F1/F2) under some conditions.
- NEW: various new VGA modes and other options for the new VGA controller (see manual)
- Improved loading speed of file inside T64 images.
- Improved keyboard handling to make the browser a bit snappier.
- BUGFIX: the size of the character ROM saved by the ROM saver was incorrect.
- BUGFIX: .wav player stops at the end of the file and does not continue playing garbage.
- BUGFIX: files bigger than 2k are displayed correctly by the .txt viewer.
- BUGFIX: when copying files out of a t64 image the resulting file was missing the last two bytes and/or the last block was missing completely.
- BUGFIX: filecopy from/to a IEC device did incorrectly abort after 1 block.
- BUGFIX: filecopy filename character set conversion was broken.
- BUGFIX: AR/RR ROM was not correctly disabled when autostarting programs from the filebrowser with AR/RR enabled as default cartridge.
- NEW: added DOS wedge command (see manual)
- NEW: added load and save commands (see manual)

The HxC Floppy Drive Emulator is a software and hardware system created by jfdn aka Jeff.
The aim of this project is to replace the floppy disk drive by an electronic device emulating the floppy disk drive (list of supported Computer/Hardware).
There are two differents emulators:
- A USB version which allows to connect the floppy disk drive interface of the computer to a PC via a USB cable.
- A SDCARD version which allows to emulate floppy disks which images are stored in a SDCARD.
Firmware SD HxCFloppyEmulator v1.7.1.2:
- Drive A <> Drive B constant polling issue corrected (Atari ST).
- Better SD Card error handling.
Firmware SD HxCFloppyEmulator v1.7.1.1:
- New embedded setting menu : To access this menu remove the SDCard and press the select button.
- By this menu you can:
- Change the floppy Interface mode.
- Change the bitrate.
- Change the track step mode.
- Enable/disable the drive B.
- Enable/disable the step sound.
- Set the user interface sound volume.
- Set the backlight timing.
- Set the standby timing.
- Check the software and bootloader version (integrity test included).
- Clear/reset the settings and reset the Emulator.
- Exit this menu…
- SD Card: Issue with some sd card corrected : Incompatibility with some SD chipset corrected.
- Write support: Timing for MFM / FM 250/300/500KBits/s write support readjusted. 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 0side 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 internals code optimization…

It was released a new firmware for the SD2Snes Flash Cartridge (Super Nintendo/Famicom) by Ikari. The upgrade instructions can be found here.
Changelog:
- SPC Player (contributed by necronomfive/blargg)
- System Information screen now shows CPU/PPU revision (contributed by necronomfive)
- Satellaview: basic data transmission packet support (makes some more games boot, thanks to LuigiBlood for assistance and sample data packets)
- Number of supported files increased to 50000 per card / 16380 per directory.
- Slight speedup of menu text rendering.
- Reduce load time of menu.
- Adjust Cx4 timing to be more faithful (Mega Man now defeats the boss in attract mode in Mega Man X2)
- adapt ROM mirroring size to file size if header information is invalid (fixes Super Noah’s Ark 3D, possibly others)
- MSU1 interface changes suggested by byuu:
- Data offset 0 and audio track 0 are automatically requested on reset. This causes the busy flags to become 0 shortly after reset/startup.
- $2000 bit 3 is now “audio error”, becomes valid after “audio busy” -> 0 set when an error occurred while preparing playback of the requested audio track write LED stays on when SRAM content changes constantly.
- Fixes:
- fix empty save files on FAT16 / incorrect free cluster count on FAT32.
- correct directory sorting (force parent directory at top of list)
- fix text corruption when entering a directory with a scrollable name.
- fix files/dirs count in system information.
- make ‘sd2snes’ directory hiding case-insensitive.
- improve DAC I²S timing.
- fix occasional palette corruption in menu.
- fix SD clock glitch on ROM loading (occasional glitches/crashes)
- fix memory write timing on ROM loading (occasional glitches/crashes)
- fix SPI timing (ROMs not loading; System Information not working)
- properly synchronize SNES control signals (occasional glitches/crashes)
- fix floating IRQ output (occasional glitches/slowdowns)
