JC64dis is a smart C64 disassembler for MUS, SID, and PRG files used on Commodore 64, also known as the C64 or the CBM 64, an oldschool 8-bit computer from the 80s.

Just like all disassemblers, JC64dis is a program that basically translates machine language into assembly language, the exact opposite role to that of an assembler.

The application works in three main areas: the memory area (from $0000 to $FFFF), preview of source, and the source itself. Working with the app is somewhat similar to working on a basic text editor, as users can format the source using a variety of commands.

A great advantage of JC64dis is the fact that almost everything can be customized. For example, users can even customize labs and some comments that are created automatically.

The program can also be used to reverse engineer a binary into a source that can be compiled again later on. Being a Java-based app, the GUI is not the most modern out there.

Nevertheless, JC64dis features a beginner-friendly interface with a basic menu bar, a top toolbar, and a two-panel editing area.

To conclude, JC64dis is a unique disassembler designed specifically for MUS, SID, and PRG files used on the old Commodore 64. To run it, users must ensure that their computers are running the latest version of Java JRE.
