A new version of the firmware for the Kung Fu Flash Cartridge by Kim Jørgensen is released.

Changelog:

• General performance optimizations.
• Tool for adjusting timing. Thanks gillham.

This release address stability issues on some C64C machines and allows the timing to be adjusted (phi2 offset). See https://github.com/KimJorgensen/KungFuFlash/tree/master/firmware#diagnostic

Please let me know if this release is less stable than v1.43 on your C64

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 v3.8.1.2a -> v5.0.0.7a cumulative changelog:

• Another internal interrupts priorities fix : Fix possible read issues with some usb sticks brand/models with HD disk images. (v5.x.x.x regression fix)
• Fix internal interrupts priorities.
• Some optimizations. (OLED I2C Layer, head step irq).
• A new series of Goteks based on the new AT32F435 is now available (PCB “SFRKC30.AT4.35″). This MCU is more powerful than the previous AT32F415 MCU. The AT32F435 has 384KB of RAM ! (This was 32KB for the AT32F415 and 64KB for the STM32F105) The AT32F435 can run at 288MHz ! (This was 150MHz for the AT32F415 and 72MHz for the STM32F105) This hardware revision removes the 32KB memory size challenge introduced by the “SARS-CoV-2″ Goteks (based on the AT32F415). This is definitively more reliable because file system cache can be properly implemented to deal with the USB stick latency. I strongly recommend this new AT32F435 Goteks hardware revision. Regarding the HxC firmware the new v5 version is now compatible with this new core. It still compatible with the STM32 and AT32F415 Goteks.
• Others changes:Artery AT32F415 Gotek now runs at 144MHz ! (the v3 & v4 run this core at 72MHz) Many changes and some fixes in the low level layers.
• The bootloader was updated too and finally gain the OLED screen support.
• The offline firmware installation (activation at hxc2001.com) now supports this new core.
• The online serial installation doesn’t support yet this core. But this will be done next week.
• Fix erroneous “No file image found !” message issue when a dirty CFG file is used on another USB stick.
• QFN32/SFRKC30.AT2 Gotek : Fix v4.2.10.10 regression : init crash due to a race condition.
• QFN32/SFRKC30.AT2 Gotek : Fix possible 7 segments screen issues. Fix possible bus gating issues.
• QFN32/SFRKC30.AT2 Gotek : Low level IO routines optimized : Faster floppy signals update.(Fix possible issues on accelerated Amiga and fast machines)
• By default don’t enable the swap file on MCU with more than 32KB of RAM. Embedded menu added to disable/enable the swap file.
• USB stick reset improved, Check USB stick block size and reject incompatible USB sticks (Fix hardfault crash). Fix possible hardfault crash if the USB stick is removed during the mount process. Bootloader : QFN32 Gotek – Fix possible unwanted update mode selection if the floppy bus is forced in low state at power up.
• Important bug fix in the write support : Fix possible Gotek crash when writing to a high density HFE image. Update strongly recommended to all v4.x.x.x firmwares users (v3.x.x.x firmwares not affected by this issue).
• Fix alternate rotary port support on Artery Gotek with 48 pins AT32.
• AT32 SFR1M44-DU26, SFR720-DU26 (SFRC2D.B Gotek PCB) support added !
• SFRKC30.AT2 PCB Gotek (QFN32 AT32 MCU) support added !
• SFRKC30AT3 PCB Gotek (TQFP48 AT32 MCU + New rotary port) support added !
• Init layer enhanced to support all Gotek variants in a better way.
• Low level layer enhanced to support all Gotek variants in a better way.
• More STM32 and AT32 MCU models supported !
• Amiga and Atari ST File selector updated to support the new v4.x.x.x firmwares series.
• Sound fixed on Artery Goteks.
• New “SWAPMEM.BIN” swap file system implemented to deal with the low RAM memory ARTERY Goteks : Better HFE format and long write operations support (Amiga, E-mu Emulator, Arburg…)
• Bug Fixes !
• Raw *.IMG PC Files : Fix the 40 tracks double sided images support.
• Build-in USB stick init / format function (custom firmware) : If the the 7 segments screen embedded menu is disabled, the format mode can be enabled by the user by just pressing both buttons with no USB stick connected.
• The eject/insert feature can now be disabled on the custom firmware page.

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

A new version of the firmware for the Kung Fu Flash Cartridge by Kim Jørgensen is released.

Changelog:

• Super Snapshot 5 performance optimization.
• NTSC timing adjustments. Thanks jpcompton, gillham, and adrianglz64.

This release should address stability issues on some NTSC machines. This is not a perfect solution and there may still be issues with some C64C machines (#135).
Please let me know if this release is less stable than v1.42 on your NTSC C64

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

The AVGCART is a FPGA based multicart for 8bit Atari computers, extensible with SIO and/or ECI/PBI cables.

• supports CAR (cartridge dump) files up to 1MB and most bankswitching types
• supports XEX (executable) files
• supports ATR (floppy image) files (read/write) – support is limited without an optional SIO or ECI/PBI cable due to Atari cartridge port constraints (e.g. SW that uses RAM under OS does not work)
• supports ATX (protected floppy image) files (read-only, SIO cable required)
• supports CAS (cassette) files (SIO cable required)
• supports AVF (video) files
• supports PDM (audio) files
• fast file search, file shortcuts, randomizer and tons of other features
• when used with optional ECI/PBI cable, it can expand ATARI memory to up to 576kB, it can also provide extra 48kB RAM to stock 16kB 600XL machines (some limitations apply)
• firmware upgradeable via SD card (no additional hw needed)
• SIDE2 emulation (compatible with U1MB and SpartaDOS X)
• ability to stack emulated cart with emulated SpartaDOS X cart, together with SIDE2 emulated HDD
• unlike some other products, most of the functionality is running inside the cart and not on the host machine’s CPU which makes it faster and more versatile (it can do stuff in parallel with host machine without having to gain 6502 control and doesn’t require soldering extra internal upgrades like Ultimate 1MB for some basic functionality like ATR emulation or memory expansion)
• compatible with 600XL, 800XL/XE, 65XE, 130XE, XEGS (cartridge shell is too wide for 1200XL, bare pcb will fit, it is also too tall for 800, can be used with cartridge door opened and door switch triggered)

Changelog (v0027):

• When used on 16kB 600XL with EXTMEM enabled, it tries to expand it to 64kB base RAM (if enough cart ram is free)
• Changed key autorepeat delay/rate
• Some fixes related to EXTMEM
• EXTMEM tweak (not all SRAM chips are made equal)
