Technical notes

LowRes NX is a fantasy console simulating an imaginary 8/16-bit handheld. It runs programs written in a custom BASIC dialect, loaded as .nx files. The libretro port is maintained by the upstream author (timoinutilis) in the same repository.

retro_load_game() copies the .nx source code into memory (libretro/libretro_main.c:490-493) and compiles it with the built-in interpreter. The boot intro is a string constant embedded in core/boot_intro.c:26. Default characters and charsets are compiled-in C arrays. The core never calls RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY. No BIOS, firmware, or external files required.

No BIOS or firmware files required.
