## Steve's OSI C4P Software Page

These are some of the highlights from my disk collection. These programs run on the C4P with floppy disk. All are in BASIC. Some require the updated OS65D3.3 BASIC with special PRINT!(xx) statements. Some programs were converted from 40-column PET BASIC 4.0 and some were written by myself. It's been so long that I don't remember the details of writing them, but I'll try to add comments as I investigate them. I also cannot guarantee that these programs are bug-free or even complete. Some may even be partly corrupted, however I did test them in WinOSI to verify they would load and run. Enjoy!

|  | ML DIRECTORY PATCH This is a machine language patch for OS65D3.3. It replaces the "DI" command (disk sector display) with code to display a directory of the currently selected disk. This program pokes the code into memory and is then available any time. You could also re-save the OS with this patch to make it permanent.

Not complete but mostly playable. I may try to finish this at some point as Pacman is one of my favorite games. Realtime joystick control.
|  | RATRUN Maze game. Find the cheese.
|  | RESCUE Save your men from the alien attackers. Realtime joystick control. Converted from PET program.
