VirtualC64 emulates a Commodore 64 personal computer on your Intel Macintosh OSx > 10.6.

I wrote the software with two major goals in mind. First, I wanted to create an emulator that can be used as a demonstrator program in a first year or second year course on computer engineering.

To achieve this goal, I have integrated various debugging capabilities that let you peek inside the CPU, RAM, ROM, or one of the custom chips. Second, I tried to make the emulator as user friendly as it can get.

In short: VirtualC64 tries to combine the ongoing fascination of the ancient Commodore computers with the great user experience of today’s Macs.

Bug fixes and enhancements:

• Enhanced sound emulation (ReSID library has been integrated)
• Fixed joystick issues on lion machines.

ACID 64 Player Pro is the sequal of Acid 64 Player and is a cycle based Commodore 64 music player designed for playing SID tunes on sound cards/devices that have a real SID chip (6581/6582/8580) on board like the HardSID cards and HardSID 4U USB device.

ACID 64 emulates the MOS 6510 micro processor, the 6526 CIA chip and partially the 6569 VIC chip to run the code of a SID tune and it controls the SID chip on the device for playing the Commodore 64 music.

What’s new in version v3.2:

• JSidDevice v1.2 support, get the new version at the JSidplay2 site.
• Increased performance for building folder tree view.
• Seeking back for some tunes could lead to stopping the voice bars.
• Small improvements.

C64 Studio is a .NET based IDE written by Georg Rottensteiner. This app supports project based C64 assembly.

The internal assembler is using the ACME syntax. In connection with Vice the IDE allows you to debug through your code and watch variables/memory locations, registers and memory.

Any other emulator can be set up as well if it’s startable via runtime arguments. C64 Studio allows you to compile to raw binary, .prg, .t64 or cartridge format (.bin and .crt for 8k and 16k). Additionally to this C64 Studio comes with a charset and sprite editor.

Version history:

10.09.2011 – 1.7:

• Added code font configuration.
• Added notification for externally changed files.
• Added intelligent dependency checks (only rebuilds changed files)
• Fixed !CT SCR mapping.
• Watch and Compile Result views are sortable now.

Regenerator is an interactive disassembler for C64 binaries. Regenerator will load any standard C64 .PRG file (or VICE snapshot) and disassemble it for your convenience.

There are a few options you can choose to change the output and a few tools to make the output look better and more useful to programmers. Regenerator runs under M$ windows and need .net 3.5 (or 4.0) runtime.

New in version 1.2 (compared to 1.0):

• You can turn Auto-Merge of Text/Data blocks that touch each other on/off.
• You can Manually Merge Text/Data blocks that touch each other.
• You can set any true type font as the display font now.
• There is a new default font used for display (hopefully better and more readable)
• Regenerator can prefix ‘~’ to operands which must be compiled as 16 bit even though their higher byte is 0. This feature is supported by 64tass 1.47 that is included in the zip file (it also has other bug fixes done by me).
• A lot of minor bug fixes and annoyances squashed.

CBM prg Studio allows you to type a BASIC or Machine Code program in using a nice Windows environment and convert it to a ‘.prg’ file which you can run on an emulator, or even a real C64 or VIC20 if you’re feeling brave and have the right kit.

CBM prg Studio is the result of merging C64PrgGen and VIC20PrgGen. Adding new features and fixing bugs in two apps which were 95% similar was a bit of a nightmare so merging them made sense.

It was also a good opportunity for a face lift and to add some new features, such as:

• Programs are project based, meaning all related source files, sprite files etc. are kept in one place and multiple source files can be linked more easily.
• Tabbed MDI.
• Syntax highlighting.

What CBM prg Studio isn’t is a front-end for tok64, cbmcnvrt, bastext or any other tokeniser / detokeniser / assembler. It’s all been written completely from scratch.
