A pixel art checker for NES, SNES, SMS and Mega Drive limits
pixcheck tests a PNG against each console's palette, attribute and tile limits. Claude's art broke them in 11 of 36 images, all NES or SNES.
Free tools for homebrew on the NES, Master System, SNES and Mega Drive, aimed at the code and art that look plausible but break on real hardware limits. Each one is tested on games or art written by Claude, and run headless in an emulator where the post says so. Start with the profiler: the lint and the checker build on what it measured.

Measured 68000 costs of common SGDK code, a lint that flags them on the frame path, and what it found in 40 Mega Drive games written by Claude.
A headless Mega Drive profiler built on Genesis Plus GX: per-frame load, dropped frames, DMA overflow and the function behind each, at 26x real time.
