...Cardco had a prototype at the January 1983 Consumer Electronics Show. The April 1983 issue of Creative Computing described it as being available for demo in a hotel room with a rent-a-guard at the door. By their account, on page 43 of the magazine, it was housed in a taped-together orange cardboard box and used the VIC’s function keys for select switches to control the games and replicated the VIC’s cartridge port so you could still plug in VIC cartridges as well. “The whole thing works like a charm,” the account concluded.

Here is BETA 2 of the Emulator adding fantastic Commodore Sound to Atari 2600 games! :)

Subtractive Analog Synth on Atari 2600 games:

Compare the soft synth soundtrack of the New SpaceInvaders and Arkanoid Airhead on the Atari and Commodore Atari emulator!

ArkanoidAirhead.bin (New Space Invaders ROM in first post)

Both sound awesome but the SID rendition is uniquely different with subtractive analog filters adding subtle harmonics to the musical compositions you will need a real C64 with a SID chip.


Awesome arcade sound effects and harmonic synth soundtrack:

Compare Starblitz arcade sound effects and soundtrack on the Atari original with the Commodore Atari emulator, like the graphics the soundtrack is enhanced and expanded with no changes to the code.


Arkanoid Airhead Trainer and Arkanoid Airhead Pro have a different sound track despite being the same program code.


You can change the version with the BW switch on the Atari 2600, but the switch setting is pre-configured on the Commodore Atari 2600 emulator for each Atari game ROM.


This could be changed to use a key like shift-lock on the keyboard, but the C64DTV and C64GS do not have keyboards so two versions of the "ROM plus emulator" accommodate the BW switch setting.



Here is the BASIC program code for the Starblitz Atari 2600 game ROM:

Here is the BASIC and Assembly program code for Berzerk 2000:

Technical details:
The programs illustrate Atari 2600 registers and system architecture being emulated in real time in the Commodore 64 Atari emulator. The ASCII art bitmap graphics and the chiptune code for the TIA are also upsized dynamically with Commodore graphical skins and subtractive analog sound in real time.



Enhanced Atari 2600 games:
Commodore graphical skins can be mapped programmatically by the loader or dynamically at runtime to enhance Atari 2600 games.



Hope everyone enjoys playing with the Commodore Atari emulator, the Dev kit should be available in December! :)
