emulators/x16-rom 48 NetBSD

This is the Commander X16 ROM containing BASIC, KERNAL, DOS and GEOS. BASIC and KERNAL are derived from the Commodore 64 versions. GEOS is derived from the C64/C128 version.

* BASIC is fully compatible with Commodore BASIC V2, with some additions. * KERNAL: -> supports the complete $FF81+ API. -> adds lots of new API, including joystick, mouse and bitmap graphics. -> supports the same $0300-$0332 vectors as the C64. -> does not support tape (device 1) or software RS-232 (device 2). * GEOS is fully compatible with the C64 version. * DOS -> is compatible with Commodore DOS ($, SCRATCH, NEW, ...). -> works on SD cards with FAT32 filesystems. -> supports long filenames, timestamps. -> supports partitions and subdirectories (CMD-style). * CodeX Interactive Assembly Environment -> edit assembly code in RAM -> save program, and debug information -> run and debug assembly programs
