Solitaire (1991)

In 1990 we had been coding intros, demos and cracks for almost two years. The local duel with BCB and HSA was over, writing demos seemed a bit pointless. So, many of the things we learned were put into two games. "Solitaire" is one of the earliest computer implementation of solitaire games, and that makes me feel good.

Solitaire is my major product. I finished it in 1991. That is the age without illegal opcodes, yet. It's 100% pure 6510 code ;).

My first encounter with solitaires took place during the mid-eighties. Around 1989 I saw a PC implementation of Klondike (named Las Vegas). It was a pretty simple, character-based program. It was obvious that our demo-coding experience was there to help us code a nice solitaire game.

Solitaire is completely my design. But it wasn't my only goal to write a game... to write an amazing one, that was what I wanted to do. Later I participated in a program contest with Solitaire, unfortunately I screwed up the presentation to the Jury and ended up in third place. I even tried to sell this game to a software house in Holland. I found the name and address of the contact person in a Hungarian Commodore magazine. The guy wasn't working for the company anymore when I sent him the demo version... That's my luck. (Later I wrote games for Windows as well.)

The game has an auto-start routine, and the directory is modified to trick the curious user. Just try to load any files from the disk (the ordinary way). A turbo loader was added as well.

  • Intro. The entire intro was coded by me. The logo and the character sets are mine as well. These ten colors I used here have an influence all over the other parts of the game, the user will know that it's the same product. The intro music was composed by Teonaki. The border take-offs were quite common for us those days.
  • Menu. The menu of Solitaire presents the same ten colors used in the intro. No technical brilliance here, just some nice graphics.
  • Rules. Again, those ten colors are used in the small logo and the raster bars. The rules are displayed in the bottom half of the screen while in the upper half the name and difficulty of the selected solitaire are displayed. In the four corners of the screen you can see the suit symbols, of course, "under" the border.
  • Game Play. All three games have different game plays. The common features are the pointer arrow and the time counter (both in the borders). The game is played by joystick, the "N" key for next and the "F" key for foundation are also used. Sound effects are Teonaki's.
  • Hall of Fame. Again the same colors in the design. And that convex lens. It's just a nice little routine from the last part of my Big Logo Disk. The 2x2 char-set is made by Crazy Speed, music by Teonaki.

Hi Gábor, neat site on your C64 history! And some pretty cool stuff you have created.
I'd be interested to get in touch, and maybe get the other disk images from your collection - for the archives of C64 scene history (e.g. Pls drop me a mail at bugjam [ at ]

C64 Corner

I don't remember exactly when I had my first encounter with the Commodore 64, neither the day when I finished my first program on that machine. But I'm sure that some months later I was programming the 6510 processor in assembly and I was drawing logos and character sets to please my creative instincts.

A year ago (1999?) I ran into a C64 emulator for the PC, the shareware CCS64 of Per Håkan Sundell. While playing the old games like "Revs Simulator", "Katakis", "Le Mans" or "Archon" I realized that somewhere in a drawer I still had my Commodore floppy disks. I borrowed a 1541 II floppy drive and a serial cable and copied all the disks' content into D64 images.


Please note that these disk images are for personal use only. These .D64 files are not distributable by any channels without prior permission of the author.

To view my Commodore 64 products I highly recommend the shareware CCS64 emulator of Per Håkan Sundell. Of course, a real C64 is the best way to experience the touch of the late eighties, early nineties. Visit the CCS64 Home to get the installer.
