A new version of the firmware for the interface 1541 Ultimate is released. This version runs on both version of the Ultimate 1541 cartridge.
Version 2.4a includes the fixes that TLR made to the firmware, and adds the following features:
- Bitfiles don’t need (and can’t) be flashed on a 250E… (fix for MK1)
- Version updated to AC for MK1 as well (otherwise the software will annoy you until you die!)
- Cartridge list shortened. This avoids crash on cart change in config.

A new version of the firmware for the interface 1541 Ultimate is released. This version runs on both version of the Ultimate 1541 cartridge.
Version 2.4 includes the fixes that TLR made to the firmware, and adds the following features:
- CRT load (just by selecting the file, not on boot time)
- EasyFlash support (reading only, writing is not needed IMHO)
- Flashing and running custom FPGAs (Ultimate-II only), especially for those who want to do FPGA development without JTAG cable. FPGA bitfile will be flashed into the spare area of the Flash memory device, and the FPGA is booted from there. So there is no risk of bricking your device. (Flashing needs to be done for every boot still, optimizations will follow.)
For the rest, a lot of work has been done ‘under the hood’; especially in preparation of a native command interface to control the Ultimate from I/O space. But since this is not yet ready, it’s not included (=not enabled) in the 2.4 firmware.

SD2IEC is a hardware mass storage device using an SD/MMC card and interfacing with the IEC bus. It is based on the ATmega644 or ATmega1284p microcontroller from the Atmel AVR microcontroller family.
The most prominent use of SD2IEC is emulation/replacement of a Commodore-1541 disk drive for a C64. Hardware and the microcontroller’s firmware is available as open source (GPL).
Changelog:
2011-12-18 – release 0.10.2
- Bugfix: End of generated raw directory was incorrect.
- Bugfix: Various compilation fixes when fastloaders are disabled.
- ULoad M3 automatically exits when ATN becomes active.
- Minor code space improvements.

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:
Differences from Beta-6f to Beta-6g:
- Implemented bit-fade in SID when no waveform is selected.
- Implemented bit-fade in SID when reading write-only registers.
- Added bits to detect in menu when disk-images need update after write actions by the emulated drives.
- Implemented “door” on emulated drive, when open drive will read dummy bytes.
- Fixed CPU instruction timing bugs discovered when comparing emulated 6510 against real 6510.
- CPU irq/nmi timing fixes.
- Implemented bit-fade on I/O port of emulated 6510.
- Fixed SID stereo mapping for D500 and D700.
- Four timers added at addresses D0AA to D0AD for menu (it can’t use CIA timers when freezing).

This is a custom firmware build for the 1541 Ultimate II by Daniel Kahlin (tlr).
This version of the firmware addresses a few things that needed improvements.
Full History:
- Rebased to the 2.3 release. (svn r88)
- Rebased to the 2.2 release. (svn r71)
- Added GPL 3.0 license as stated by Gideon in the 1541 Ultimate-II (Fixes Bug 110 “License file (GPL) missing in source repository.”)
- Fixed filename length in print out during DMA loading.
- Added “Real Run” for files inside .d64 files which mounts, loads and runs using the BASIC prompt.
- Added “Run Tape” for .tap files which mounts tap and does LOAD/RUN using the BASIC prompt.
- Added “Run Disk” for .d64 and .g64 files which mounts, loads and runs “*” using the BASIC prompt.
- Added detection of cyclic links in .d64 directories and files. (Fixes Bug 94 “Hang when entering diskimage.”)
- Added sanity check of sector links in .d64 directories and files.
- Search until end of directory, even when hitting files with t=0. (Fixes Bug 98 “No dir listing with DEL file linked to T0, S0.”)
- Based on the 2.1 release. (svn r65)
- RUN/LOAD/mount has been reworked to hopefully be more clean. (Fixes Bug 109 “CLR/HOME ctrl code sometimes visible on running file from browser.”)
- Made DMA loading simulate the look of normal loading.
- Corrected mixup of disk id. (Fixes Bug 79 “id1 & id2 mixed in disk_image.cc (Skate or Die disk/sector id bug)”)
- Cherry-picked fix for SDCard rename from trunk. (svn r66) (Fixes Bug 105 “Renaming SDCard via U-Menu corrupts root directory.”)
- Submenues can now be exited using CRSR-left in addition to R/S. (Implements Wish 77 “Exit submenu using CRSR-left in file browser.”)

- Updater updated: Now possible to clear all configuration pages in flash.
- Issue fixed with configuration of objects that did not have a config page yet (write/effectuate decoupled).
- Issue fixed with re-freezing into an empty D64 (or file with headers but no items); caused a blank screen.

- Simulation environment set up for REU.
- REU verify bug fixed. More testcases to be added.
- …/target/simulation/sim/$ make reu_tc_1.gui will start ModelSim with the REU testcase.
