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 reads game content entirely through the retro_game_info data buffer (need_fullpath = false, libretro_main.c:317). The .nx source code is copied into memory at retro_load_game() (libretro_main.c:490) and compiled by the built-in interpreter.
The boot intro sequence is compiled from bootIntroSourceCode, a string constant embedded in boot_intro.c -- not loaded from any external file. The core never calls RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY. There is no code path that reads any file from the system directory. No BIOS, firmware, or boot ROM is required.
The virtual machine provides a 160x128 screen, 64 colors, 256 8x8 sprites, 4-channel sound, d-pad + 2 buttons, and a pause button.
