Does anyone have a source for a tutorial of that kind ? Freeload for example.

IMHO Das Anti-Cracker Buch (in german) has all the information needed.

I'll check this one. I translated the entire book with AI to English.

I cover the whole process of converting Gauntlet from tape to disk in this video: https://youtu.be/1MXB6b6mm7c
Starting from the hardware, understanding the loader code, extracting files, and then altering the code to load from disk and creating a disk.

Readable. However I don’t think there’s any info on how to replace a tape loading routine with a disk one there.

Cool! I checked it and I think I need to watch it over and over as the whole understanding the loader part is not very digestible to me. I see you replace the routine very easily but I need to sit and try myself. I guess one can rip the levels with programs like Tapex and then just replace the loader.

Yes the state machine of the loader is quite hard to understand. You could use a tool that magically extracts the tape data, but I think it is worth trying to understand the lower level code, what data format it expects, and then how to translate that into extracting data from tape.

Being able to understand the lower level process allows for working on games that are not parsed well by a magic tool.

I suggest trying to figure it out yourself and if you get stuck then ask questions, you'll have more fun, and understand the process better than using tools (until you know how to do it) and get more out of it that way.
