Windows & C64

Cross Assembler and Virtual Floppy Drive C64Connect

C64Connect is a tool by me which runs under Windows. (Updated April-01-2007)

• C64Connect is a cross assembler for the 6502 CPU. In fact the cross assembler is compatible with the powerful macro assembler TurboAss+ of the C64.
• C64Connect is a utility for exchanging file formats between C64 diskimages, C64 program files, C64 sequentiell files.
• C64Connect is a virtual floppy C1541 drive for a real physical C64. That is, files of diskimages can be loaded and saved by a real C64. However, in this case the PC has to be linked with the C64, and the C64 kernel must be exchanged ba a special kernel.                 

  (Extremly comfortable: you don't need to touch the keys of the real C64 to load and start programs; you just double click a C64 program file (*.prg) in Windows Explorer, then the C64 will be hardware reset automatically, and the program will be loaded and started automatically within a few seconds. You don't even need a C64 screen, in case you just want to listen C64 music files on your real C64, which you comfortably start from Windows Explorer. You can remote the C64 keys with your PC keyboard like ghost writing, and vice versa. Don't hesitate to send me an email - any feedback is wellcome.)

Manual for C64Connect

Source-Code for C64Connect/PC-Connect - (source code for Visual C++ 6.0) - One may modify or use parts of the source code, but one should state in ones version or programm that one has modified or used parts (also stating which parts) of C64Connect/PCConnect. One should apply all standard ethic rules for open source.

To emulate C64 programs you may use the great C64 emmulator CCS64 by Per Hakan Sundell.

Commodore C64

Game Cydonia

Cydonia is a unfinished game by me for the C64 written in 1989-1992. Cydonia is a jump and run game and is inspired by Great Giana Sisters for C64 (which in fact imitates Super Mario Bros). The game was significantly technically modified several times. You can download different versions of the game divided into three categories corresponding to different stages of development of Cydonia.

• 1 Way Scrolling Versions of Cydiona (1 way scrolling shifting by 2 pixels/frame with colorram scrolling)

  In the game buy the cyan "S" (Speed) in the department store; otherwise you walk very slowly. The green balls in the store are shots. (The sounds of gpak610.prg and gpak615.prg are taken from Last Ninja 2 and R-Type, respectively.)
  
  gpak610.prg
  gpak615.prg
  gpak641.prg

• 4 Ways Scrolling Versions of Cydiona (4 ways scrolling shifting by 4 pixels/frame with colorram scrolling)

  The following versions are older versions of Cyodnia in this category I had on disk. Press Restore during the intro to jump to the world-editor. There load for example "02world" and "00block" at first.

  disk35a.d64
  disk90a.d64
  disk92a.d64
  disk108a.d64
  disk112a.d64
  disk120a.d64
  disk122a.d64
  disk122b.d64
  disk123a.d64

  With some great effort and analysis of old source codes I was now able to reassemble the then latest version of Cydonia in this category for which I had no executeable copy on my C64 disks. It is the state as it was 1991. I have now switched off the "more than 8"-sprites system, but one can also download the version with the orginal sprite system. I extra programmed the cross assembler only for this task, the reanimation of the then latest version of the colorram-scrolling versions of Cydonia. Here are the results:

  cydonia1991.d64    (Here I have inactivated the "more than 8"-sprites system; this version looks somewhat cleaner than the version with more than 8 sprites.)
  cydonia1991.zip    (The same version, but now with source code.)
  cydonia1991s.d64    (The same version, but with the original "more than 8"-sprites system. Same source code; only the label "spritesystem" is set to 1.)

• Cydonia'92 Versions of Cydiona (4 ways scrolling shifting by 4 pixels/frame BUT WITHOUT colorram scrolling)

C64 Sounds

Here you find sounds and soundmonitors I programmed for the C64.

• Soundmonitor First Generation

  After the sound monitor has been started you start the sound with "F7" and stop it with "RUN/STOP". Use "Return" and "Shift+Return" to edit. The sounds in this categorie are just brief patterns of music.

• Sounds completely composed in assembler

  They are completely composed in assembler rather than using a soundmonitor. The sound routine is written newly and different to the sound routine of the soundmonitor of the first generation.

• Soundmonitor Last Generation (SOMON)

  Here is the second and last soundmonitor by me. The sound rouitne seems (as far I can remeber it) the same as the sound routine of the latter category. To start the soundmonitor load the file "boot". In the monitor one loads a sound with the key sequence "leftarrow" and "L". The sound can be started and stopped with the key sequence "leftarrow" and "leftarrow". ("leftarrow" = "^" in emulator.)

  Here I made C64-"RUN"-able versions: gaehn2start.prg    grus4start.prg    k3start.prg    krkl2start.prg    land5start.prg    rap20start.prg

• SID-Files (download)

  I am indebted to Ramos from the HVSC Crew who converted many of my sounds to SID-files.

Texteditor Cadvec

Cadvec is a text editor with similarity to the editor of Turbo Ass. In the editor you save (or load) with the key sequence "leftarrow" and "S" (or "L"). Turn Insert Mode on and off via "Shift"+"Ins Del".

It was my intention to use Cadvec as an editor for "programming" the advesaries (in a special mini language) of the game Cydonia (version Cydonia 92). But I did not go so far since soon afterwards I gave up the development of Cydiona for good.

Commodore C16

Game Pac 16

PAC16 is a pacman variant for the Commodore C16. I programmed the game in Summer 1987 (with the C16 implemented monitor programm). The game must be started with SYS11420. During the game use the cursor keys and "Return" in the menu and the keys "A Y , ." and "Shift" (german keyboard) when playing.

Examples of downloadable C16 emulators are YAPE (modern) and WinEMU (older).

Amiga

Here I am intending to insert some Amiga assembler files and source codes..
