What Parlor does not include
- No commercial games, and no links to places that distribute them. Parlor plays files you already own.
- No Nintendo DS BIOS or firmware. Those are copyrighted; you supply your own copies. See the Nintendo DS guide.
- No analytics SDKs and no third-party trackers. See the privacy policy.
Accuracy
The Game Boy core is verified in Parlor's own test suite against dmg-acid2, cgb-acid2, mooneye and Blargg's test ROMs; golden framebuffer hashes are re-recorded only on a deliberate core bump, so a regression in rendering fails the build.
