Flaschback Commodore C64

Commodore C64 core for Multiple Classic Computer™



The C64 initial design started in January 1981 from a subsidiary company from Commodore called MOS Technology. They decided to develop the next generation graphic chip set called VIC-II and a sophisticated sound chip called SID.After presenting the idea to create a low cost computer with their chip set and the 6510 8-Bit CPU to the CEO from Commodore Computers (Jack Tramiel), he decided that the machine should have 64kB of RAM. The design team built the first prototype and it was a direct hit at the Consumer Electronics Show CES 1982.A full product started in fall of 1982 and the C64 sold for a retail price of 595$. In addition of being the most powerful machine for this price in the market it took the market in a storm. During the C64 live time (1982 – 1994) an estimated 17 million units sold world wide.

Games and Applications:

Approximately 10,000 commercial software titles were made for the Commodore 64 including development tools, office applications, and last but not least a lot of games.

Beside this the C64 is credited to start a demo scene development. It is still being actively used as a demo machine, especially for music and live retro gaming sessions. Unfortunately, the differences between PAL and NTSC C64s caused compatibility problems.

The vast majority of demos run only on PAL machines. ArcadeRetroGaming overcomes the limitations of the original C64 for PAL and NTSC.

Original architecture and re-implementation:

Commodore developed and used the most powerful CPU for the C64 in this time the 6510. The video chip VIC-II 6567 can produce 16 colors. The now legendary SID 6581 sound chip was astounding for its time. It could play three different “voices” in sophisticated patterns. In the later models of the C64 it was replaced with the 8580 SID chip.
ArcadeRetroGaming (ARG) re-implemented the whole C64 chip set according to specifications [2,3] and with support out of the retro gaming community.

Special thanks to Peter Wendrich who supported this effort with his 6510 CPU design.

To cope with some limitations of the original C64 design the ARG engineering team around Frederic Requin included the following features and enhancements:

One C64 core supports PAL and NTSC with a simple software switch

CPU performance enhancement up to 50% to enable smooth representation of a PAL game in NTSC mode

Enhanced audio performance with two built-in 8580 sound chips

Disk emulation to read and write SD-cards

Disk Drive and CPU performance overlay menu

Switching between different disk images

USER menu reads and displays .T64 and .D64 images from the SD-card
PREF menu for video settings, 1541 drive settings and boot options

High resolution VGA output

Games and Demos:
To combine the powerful hardware with the right content, ARG joint forces with Cloanto® supporting C64 and Amiga Games and demos from the C64 Forever™ and Amiga Forver™ series.


In addition, the system supports updates of applications, games and demos via the C64 Forever™ PC software.
