Hi! A long time ago, I created a library for cc65 called Fields. It provides code to provide some UI support to cc65 programs, including dialog box-like data entry and menus. It currently supports the C64, Plus4, C128 and Apple2enh targets. It may also support the Atari 8-bit consoles, but such support is untested. :( You can find it at c65 additions - Manage /ui at SourceForge.net. Try it out!
