Today, we can change and swap the kernal about and try out new things a lot faster and easier than it used to be.
We’ll go over the different levels of things that can be done, from experimenting with simple kernal code changes to options for swapping out the installed and in-use version!
f1: LIST: + CHR$(13)f2: OLD + CHR$(13)f3: RUN: + CHR$(13)f4: Toggles something? ON/OFF (maybe fastload?)f5: LOAD + CHR$(13)f6: SAVE”f7: @$* + CHR$(13)f8: LOAD + CHR$(13) I also found a couple more: CTRL + f1: @N* + CHR$(13)CTRL + f7: Disable Function Keys Now before you go pressing CTRL + F1 be warned, THIS WILL FORMAT THE DISK IN DRIVE 8, and give it a label...

PiffyDOS – Programmers JiffyDOS JiffyDOS from CMD has almost become a de-facto standard for the Commodore world. It’s compatibility, speed and features makes it the natural choice for users today. I found it very interesting how CMD managed to squeeze everything into that 8kb of ROM and started to disassemble the code. With the Omicron re-assembler I got about 100k of text that i...
Prologic DOS and Prologic DOS Classic (version 1.6) was a quick loader that included a module on the 1541 floppy disk drive and a module for the user port or expansion port of the C64. The whole thing was connected via a parallel cable and supposedly ensured that an acceleration of 200 times the normal speed could be achieved. It was distributed by Jann...
Here is a curated list of known C64 kernal and character ROMs. The list will be updated whenever new information becomes available. Some require additional hardware or mods, some do not. Details are provided wherever possible.
Introduction============This is a modification of the Commodore 64 kernal with improved support for thewonderful SD2IEC device by Ingo Korb. Either burn the 8K kernal file to an EPROMand replace the original kernal ROM chip of your C64, or use a device that canoverride the kernal ROM (e.g. 1541 Ultimate, Turbo Chameleon 64, EasyFlash≥). Changes since 1.0:– the browser is started with F7 instead of...
