Program that detects type of your hardware in Commodore 128.

Also added recognizing 64HDD drives / SuperCPU / JiffyDos and a better detection of MMU and RAM size, not works correctly in VICE.

Optimized for 80 columns mode. Thanks to Christian Johansson.

A new version of the firmware for the interface 1541 Ultimate II is released.

Some major fix:

• Added: Built-in flash protection to avoid more units to ‘die’.
• Fixed: Joystick Right on PRG file still crashes UltimateII.
• Fixed: Mount & Run starts disk mounted Write Protected.

Finally! after a long time the new version of the Firmware for the interface SIO2SD is realesed under GPL Open-Source.

The SIO2SD is a device that allows you to load games/applications into any 8-bit Atari XL/XE computers via SIO interface from SD/MMC cards.

Changelog:

• Configuration is now available from Atari Screen – press K3 key (no need to disconnect the cable from the SIO).
• Loader for the executable files has been replaced with a new version.

With this tool you can convert anything into MUIFLI (interlaced) or NUFLI (static), such as seen in Crest Slide Story , Carrion’s OLDSCHOOL Pixels 100% or BluREU.

This tool run under OSX/Win/Linux (BSD).

SD2IEC is a hardware mass storage device using an SD/MMC card and interfacing with the IEC bus. It is based on the ATmega644 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:

2010-08-06 – release 0.10.0pre1

• GEOS 2.0 support (d64/d71/d81 images only)
• File-based M-R emulation.
• Removed “oldnkc” configuration.

Some new Games & Utility for Commodore VIC-20.

• Raw tape transfer 1.0. Tool to transfer files from tape to disk, including tape headers. Useful for analysing original games. Can transfer any memory region on an unexpanded vic.
• TGA – The Great Adventure. Conversion from the Commodore 64 of a classic Italian multiple-choice text RPG written by Alessandro Castellari in 1983. Try it on your VIC with the nice graphics of hi-res and multi-colour screens.

iAN CooG Site has been update with a new version of the Generic C64 prg Unpacker v2.23 (Source included).

History:

v2.23 – 2010.06.12 – 2010.07.30

• Found a Time cruncher hack expecting registers set by JSR $FD15 ($31/$30/$ff), now it’s handled correctly in pass 1.
• In verbose mode, now also number of iterations and total cycles taken by the simulated CPU are printed, just to see which is the slowest&fastest unpacker.
• Raised max iterations to support VERY intensive unpackers like ALZ64, worst testcase I found needs 27097007 (0x019D77AF) iterations to finish unpacking. This cruncher isn’t really meant for crunching programs ranging from $0801 to $ff00 due to its slowness, but still has to be supported even when abused =) New max value is set to 0×02000000, should be more than enough for anything that actually reaches end of unpacking, and won’t cause too much delay with programs that can’t be really unpacked or with endless loops.

My SIO2SD interface is dead (without any valid reason) after 2-3 hours of playing demos/games.

I have tried to reprogramming the firmware with a STK500 USB ISP Programmer and the tools AVRDUDE and it has worked perfectly.

CBM-Command is a disk manager for the Commodore 64 / Commodore 128 / Commodore VIC20 / Commodore C16 computers. It is written like Norton Commander or Midnight Commander, but is much simpler due to the target platforms. Both the C128/C64/VIC20/C16 have their own native version of the application.
