- CI: new "Build Examples" job compiles all .ne files and validates the output ROMs have correct iNES headers - Examples: add notes explaining that sprite names (Smiley, Ball) are parsed but not yet resolved — all draws use the built-in CHR tile 0. Custom sprite declarations come in M3. - Codegen: explicit `let _ = &draw.sprite_name` to document the intentional skip, with comment about M2/M3 scope https://claude.ai/code/session_01W6eQFStA66EuMKHUFo2rx3

// Hello Sprite — the simplest NEScript program.
|
|
//
|
|
// Displays a sprite on screen and moves it with the d-pad.
|
|
// Build: cargo run -- build examples/hello_sprite.ne
|
|
// Output: examples/hello_sprite.nes (open in any NES emulator)
|
|
//
|
|
// Note: In M1 the sprite name in `draw` is parsed but not resolved.
|
|
// All sprites use tile 0 from the built-in CHR data (a smiley face).
|
|
// Sprite declarations with custom tile data come in M3.
