==== AdvEditC64 - Advanced Commodore Editor ====
//under active development// \\
Advanced Commodore Editor is a native, full-screen text editor designed specifically for the Commodore 64, with special attention given to the C64 Ultimate and its USB-based storage workflow.

The editor is inspired by the philosophy of the Linux nano editor:
Simple controls, fast interaction, minimal cognitive overhead, and clear on-screen prompts while respecting the technical constraints and historical behavior of vintage hardware.

==== Ultimate64-sid-player ====
//under active development// \\
Plays SID songs from a directory on your C64. \\
Run sid_finder.prg on your C64, in the directory where your SID files are, or specify the path. Enable Web Remote service, configure the config file, then run the python script to have it play the songs in the directory. (See github for more details) \\
The difference between this and remote sid playing through the web manager for C64U is this can play multiple files without interaction, random and loop, like a playlist. \\
Known limitations/possible bugs:\\
1. Filename length, if it cannot read .SID the file might not get detected. \\
2. Max number of files not tested, only tested with 7 SID files. \\
Disable Web Remote service when you turn off your C64U, it might corrupt Flash memory. \\
This is a ALPHA release (31th of December 2025)  \\
