Here is a *small* part of the C64 cross tools (10 included in this pack!) I wrote during the past years. I make them public today by releasing the most stable and useful ones. Have a look at the summary for the complete list!
They are Win32 command line tools. Please don’t cry for a conversion for your platform because actually I WILL NOT make any effort in this way. They have been made in C with Visual Studio 6. If you cry very loud I can provide very interested and motivated persons the sources but this is a real mess because there are lots of source files and modules (.obj files).

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:
2009-03-08 – release 0.8.0
- Direct sector access of the real storage device
- Ignore DEL files in file_open
- Drive mapper
- EXOS V3 fastloader support
- Requires avr-libc 1.6.x
2009-03-07 – release 0.6.7
- Bugfix: Close previous file if secondary is reused without close
- Bugfix: Minor Jiffy timing fix on EOI

Some new Games & Tools for VIC-20
- VIC Nuclear Power Plant simulator (Conversion from Commodore PET of a classic Nuclear Power Plant simulator. Play it in the glory of 40 columns!)
- How Many 700 (Enhanced version of How Many)
- Un (original card game, the object is to be the first player to rid yourself of all the cards in your hand before your opponents do so)
- Moon Patrol (BASIC port of Moon Patrol arcade)
- Ouranos! (Weather War – Conversion from Commodore PET of the classic Weather War game. Play it in the glory of 40 columns!)
- VIC-SSS (Software Sprite Stack – A programmer’s API to quickly develop arcade-style video games. Software sprites are rendered using a custom character matrix of sizes ranging from 8×8 to 16×16. Flicker-free video using double-buffering with the option of tear-free video for both NTSC and PAL machines)
- Quikman 8K (Improved arcade version of 2008 release making use of the new VIC Software Sprite Stack video effects and more features making it closely resemble a popular 1980 coin-op arcade game)

MultiColor is an image manipulation tool for Commodore 8-bit computers’ graphics formats. It is an old-school painting program for graphicians but not an image converter. Currently VIC-II multicolor bitmap is the only supported image format.
Features:
- Written in C++, so it’s quite fast and no special runtime is required.
- Can be compiled for many platforms, because it uses wxWidgets.
- Can load Koala and Amica, file type is detected independently from file name.
- Behaviour when hitting the color-per-cell-limit can be selected.
- Undo/redo.
- Tools with realtime preview (e.g. Line)
- Basic TV emulation.
- Zoom, with grid at higher zoom factors.

This program converts images to a new c64 graphic format known as MUCSU Hires (MUltiColor Sprite Underlay Hires). It is merely a hiresolution bitmap image with an X expanded multicolor sprite underlay. The Hires underlay variant of this mode has been created before (known as extended hires).
After reading a few forum posts mentioning that the multicolor version of this mode was unrealistic and would provide too many restrictions, I decided to produce this converter to prove that this is not the case as well as wanting to use this particular format for my own production.

Mirage has released a new version of this cool painting program can support C64 graphics mode with file export in (.PRG) format.
This version needs windows 2000 or higher and dotnet 2.0, which you can download from microsoft.

The PLA chip (906114-01) used in the Commodore C64 is a generic 82S100 gate array with custom programming. Its logic functions were dumped and reverse engineered by the community and are available from a variety of sources. They’re reused for this particular PLA replacement in the FPGA Arcade 28 pin DIL CPLD board.
Two approaches exist to build such a PLA replacement:
1. Implementation based on a truth table with 216 entries, each entry consiting of 8 bits and programmed into an EPROM chip.
2. Reverse engineered logic equations programmed into a PLD.
Both approaches result in the same logic functionality when implemented in a CPLD. Since equations are more common for CPLDs, I chose this implementation style for the final design. However, there’s a variant for the truth table available which has been verified in simulation but not in real C64 hardware. Following are descriptions for both of them.
We have run simulations proving that the equations perfectly match the truth table, so both compiled outputs are effectively identical in the C64 implementation discussed here.

Forth, the Language.
Forth is a different language. It’s aged and a little weird.
What’s cool about it? It’s a very low-level and minimal language without any automatic memory management. At the same time, it easily scales to become a very high-level and domain-specific language, much like Lisp. Compared to C64 Basic, Forth is more attractive in almost every way.
It is a lot more fast, memory effective and powerful. Compared to C, specifically cc65, the story is a little different. It’s hard to make a fair comparison. Theoretically Forth code can be very memory efficient, and it’s possible to make Forth code that is leaner than C code. But it is also true that cc65 code is generally much faster than Forth code.

Java Ice Team Tracker 64 is a java based music tracker (editor) for creating music for SID chip of Commodore 64. Instruments are totally based onto tables for full control of sound generation.
The new version comes with some bugs fixed and new features:
- Option: temp directory is automatically given by the systemOption: activate the disable real time compilation option.
- Option: add Nimbus theme.
- Patterns: add cut functions and shortcut to cut/copy/paste/clear/select.
- Patterns: add mute/unmute playing of the voice.
- Tracks: fix semaphore red bug when press play and no compilation in background done.
- Tracks: Report when there is a sound problem (sometimes the sound core library is not able to have a free sound line to use) when playing the tune.
- Player: fix track repetition command errors.
- Player: fix note transpose for instrument.

DirMaster is a Windows-based GUI tool useful for the management of common (and uncommon) emulator formats (such as .d64, .d81, .t64, etc) as well as native archival formats (such as .arc, .sda, .lnx, etc).
New in this version:
- .t64 *write* support.
- .t64 “Run In” support.
- disk/archive content preview on file open dialog.
- remembers window location/size between launches.
- cross linked sector check.
- “Run In” can now operate from a transient disk or tape image; this creates a temporary image which is passed to the chosen emulator; temp images are deleted when DirMaster exits.
- configurable character replacements for exported file names.
- and various other user interface tweaks and bug fixes.
