about

nx_chip8_gate.nx -- NATIVE correctness gate for nx_chip8 (R0.3). Runs a hand-assembled program that exercises set/add/add-with-carry/set-I and two DXYN sprite draws (draw then redraw -> XOR clears + collision flag), and checks registers, the carry flag, the framebuffer, and collision. Proves the CPU + display logic; the same base-relative core then compiles to wasm for in-VM + browser verification.
