Sample programs

The directory "64prgs" contains some little sample programs to show the capabilities of Frodo/Frodo SC. Except for "dadb" and "lrborder" they are all loaded with LOAD"<name>",8,1 and started with SYS49152. To do so, you have to set "Drive 8" in the settings to "Dir" and set the path to '64prgs' so Frodo will find the programs.

The programs were written by Pasi Ojala, Marko Mäkelä, Andreas Boose and me. If you like, you can try them on other emulators or on a real C64.

dadb

A program running in the color RAM (press space), requires Frodo SC

de00all

A program running in the address space $de00-$dfff (press space), requires Frodo SC

dycp

Demonstrates the FLD effect (flexible line distance)

lrborder

sprsync

tech-tech
