A new version of the firmware for the AVGCART (SD multicart for 8bit Atari) by tmp is released

Changelog (v0024):

• PDS/COV/COS files run PDSPLAY/COVPLAY/COSPLAY
• added ability to select (TAB) CAR files
• selected files (ATR, CAS, CAR) don’t have to be in the same directory anymore, selection is cleared only after returning to the selector

• search now allows navigation during searching and editing search string
• CTRL-L disables item shortcuts and allows starting search by typing instead of ‘/’
• ESC stops search, exiting search requires 2x ESC (to prevent accidental exit when search stops at the same time user tries to stop it)
• disable cart was changed to SHIFT-ESC
• short filenames should finally (hopefully) have proper case
• filenames longer than screen width should be (finally) properly sorted
• type 57 (2kB) fixed
• right cart button will disable cart for carts <= 16kB (to make some CS turbo carts work)

New keys:

• SPACE – run selected files (ignores item under cursor)
• CTRL-L – toggle key shortcuts

Changed keys:

• ESC -> SHIFT-ESC (disable cart and reboot)

Changelog (v0023):

• [ECI] Auto-enable cart menu after reset (CTRL-SHIFT-E to enable, CTRL-E to disable)
• [ECI] Patched OS for ATR emulation is forced as ROM, not just loaded into RAM under ROM, increases compatibility
• [ECI+SIO] When emulating ATR, HSIO patched OS with inverted OPTION (BASIC off) is forced

Changelog (v0022):

• [ECI] EXTMEM support up to 512kB (CTRL-SHIFT-M to enable, CTRL-M to disable)

A new firmware update for the ARMSiD has been released by Nobomi.

News features and fixes in FW 2.13:

• Further optimization of code speed and size. Also bus operations are faster, finally “paddles” are successfully read on NTSC machines even with the oldest HW versions of ARMSID (with components on top) !
• ARMSID start is also faster. Instead of hundreds of milliseconds, ARMSID is fully functional in less than 15 milliseconds after power-up !
• Added the possibility to “fix” the so-called ADSR bug, i.e. a bug in the envelope generator, which is inherent to the original chips and is reproduced in ARMSID too. This is not needed in the C64 for compatibility reasons, but if you use ARMSID in synthesizers, you might be interested in this feature.
• Slightly modified quality (Q) of filter circuits for even more faithful reproduction of MOS8580.

Ikari has released a new firmware for the SD2Snes Flash Cartridge (Super Nintendo/Famicom). The upgrade instructions can be found here.

Sorry for the delay, but it just escaped me to post it here.

Features added:

• [All] USB (usb2snes) support by RedGuy
• [All] save state support (via USB/savestate2snes) by RedGuy
• [All] stand-alone save state features by FURiOUS
• [All] some compatibility improvements and optimizations for stand-alone save states by ikari_01
  • Add support for YAML list items for multiple savestate_fixes entries per game
  • Add support for simple bitwise operations on savestate_fixes patches
  • Add support for verbatim code execution on savestate_fixes patches – notably fixes Star Ocean (decompressed) save states (however the save state hook still needs CPU time optimization to prevent music glitches in Star Ocean.)
  • Add IRQ support on top of NMI for the save state hook – this enables save states on Out Of This World and possibly other games that only use IRQ. Also fixes controller input capture on a number of games so the game-specific input hacks could be eliminated.
  • Moved save state code outside of the USB hook area to make room for USB hook execution.
• [All] SGB support by Redacted173.
• [All] favorite games list by freelancer42

Fixes:

• [All] Fixed data caching bug in MSU1 data extension which could cause wrong data to be streamed
• [All] Savestates: do not try to capture data that is already in cartridge space anyway (e.g. SRAM). Fixes text distortion in Near’s Bahamut Lagoon translation when loading a state.
• [All] Fixed YAML config parser to support comment signs after list start items
• [All] Fixed SNES open-bus contamination (fixes sprite flickering in Near’s Bahamut Lagoon translation, certain speed runs that rely on open bus behaviour)
• [All] (hopefully) fixed rapid data line toggling sometimes resulting in address line glitches, causing random crashes in extreme cases, and occasional garbled graphics on SMRPG among others
• [All] Fixed data integrity problems when loading BSX games

Jean-François DEL NERO (who’s behind the HxC SD Floppy Emulator) recently has released a version of the HxC emulator firmware that is compatible with the STM32 chip used in the Gotek floppy emulators.

This means that the great functionality of the HxC SD emulator is now available on cheaper and more widely available hardware.

The bootloader to convert the Gotek floppy drive in HxC compatible must be purchased on the website HXC 2001 by sending an email to Jean-François DEL NERO. The price of the bootloader is one-off 10 Euro per Gotek that you want to update. Future updates of the software are free and can be made from a USB stick

The HXC Usb (Gotek) firmware supports: + many more….

USB Stick STM32 (Gotek) HxC Floppy Emulator Firmware v3.4.16.4a -> v3.8.1.2a cumulative changelog:

• Build-in USB stick init / format function :
• The USB stick can now be formatted/initialized for the “Image-less mode” by the firmware.
• Remove the USB stick, press both buttons to enter the embedded menu and select the sub menu to activate the format mode :
  •  - 7 digits display “d” menu entry -> Should display “For”
  •  - OLED display “Format USB Key” menu entry.
  • Then insert the USB stick you want to format.
  • WARNING : Formatting will erase all data on the USB stick !
  • The default built-in image is an HD 1.44MB Floppy disk, but you
  • can select another built-in image on the firmware customization
• SFRKC30 / SFR1M44-U100LQD Gotek support enhanced :
• The new rotary port is now supported.
• New explicit U100LQD OLED configuration.
• (Specific binaries for this new Gotek are now provided in the “New_U100LQD_Gotek” folder)
• The detected hardware model can now be read in the embedded menu
• (Sub menu ‘F’ for the 7 digits Gotek and in the “FW/HW version” sub menu for the OLED Goteks).
• Hardware ID definitions :
  • 000 : Original STM32F105 Gotek (64KB of RAM)
  • 001 : 64 pins ARTERY AT32F415RCT7 on an old STM32 Gotek board (32KB of RAM)
  • 002 : 48 pins ARTERY AT32F415CBT7 (New board) (32KB of RAM)
