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:
- Fixed a bug that caused the emulator to crash on startup on some machines.
- VirtualC64 supports OS X Lion.
- Preference panels are now tight to their individual virtual machines.
- CIA debug panel has been redesigned.
- Deprecated CoreAudio API calls have been removed.
- Fixed a bug in the BCD to binary conversion routine.
- Fixed a bug that caused the TOD to wake up too early after reading the tenth of a second register.
- Thumbnail images are now rendered properly when switching from PAL to NTSC and vice versa (issue #107)
- Fixed a bug that caused keyboard events to be rejected when the main window got focus (issue #110)
- Fixed a bug that caused a discolored line to appear at the right border of the screen texture.
- Yet another startup animation.

Autopsy:
from Wikipedia:
The KC 85 (‘KC’ meaning “Kleincomputer”, or “small computer”) were models of microcomputers built in East Germany, first in 1984 by Robotron (the KC 85/1) and later by VEB Mikroelektronik “Wilhelm Pieck” Mühlhausen (KC 85/2, KC 85/3 and KC 85/4).
Due to huge demand by industrial, educational as well as military institutions, KC 85 systems were virtually unavailable for sale to smaller customers. They were based on the U880 CPU (an East German clone of the Z80), with clock speeds of 1.75 and 2 MHz.
There were two main lines in the KC 85 series, the KC 85/2 (project name HC 900) to /4 and the KC 85/1 (project name Z 9001) by Robotron, which was a different system (only the CPU and the name were the same, but later the format of saving the programs on tape cassettes and the BASIC were also made compatible). In 1989, VEB Mikroelektronik Mühlhausen came up with the KC compact, but due to the GDR collapse very few units got actually produced and sold and — being a CPC clone — it was a KC in name only; thus it is usually not counted among the KC family.

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.

The author “Ghislain” write:
This month marks the 20th anniversary of Realms of Quest. It was in the Summer of 1991 that I embarked on making a computer role playing game for the Commodore VIC-20. I was successful in completing the first one, but I had given up in creating a sequel shortly afterwards. I did create about 20 monster portrait graphics pixel by pixel with a simple graphics program, however.
In 2004, I programmed a “mini” version of Realms of Quest II intended for the Minigame Competition; minus the portrait graphics, because to use them would surpass the 4K limit that the competition required.
So twenty years after I had made the original Realms of Quest I, I decided to revamp the first two games. And so I took the portrait graphics I had made in 1992-93 and combined them with the Minigame version of Realms of Quest II. So finally after all these years, there is a fuller and more complete version of the middle of this CRPG series.

This project by Frank Buß is a cheap solution to connect a digital joystick to a PC using the USB interface.
The interface uses Freescale microcontroller that will simulate a USB keyboard and translates the joystick signals to keyboard signals.

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:
31.07.2011 – 1.5:
- Fixed bug in parsing !byte with binary values.
- Fixed bug in file info storage, sometimes error messages were accredited to the wrong file.
- Fixed bug where warnings were not displayed (segment overwrite).
- Added charset/sprite functions as buttons.
- Changed charset copy/paste to always use clipboard
