{{#seo: |title=GameBrew |title_mode=append |image=144ptestsuitegb.png |image_alt=144p Test Suite }} Size-optimized ports of Artemio Urbina's [https://github.com/ArtemioUrbina/240pTestSuite 240p Test Suite] to 8-bit consoles. The Game Boy ports are in assembly language for speed and size efficiency. Some functionality has been rearranged to fit the controller or to combine the function of similar tests. Some help pages have been rewritten for completeness, conciseness, and English usage improvements. Some tests' graphics have been replaced to keep the software free. == Screenshots == https://dlhb.gamebrew.org/gbhomebrews/144ptestsuitegb2.png https://dlhb.gamebrew.org/gbhomebrews/144ptestsuitegb3.png https://dlhb.gamebrew.org/gbhomebrews/144ptestsuitegb4.png https://dlhb.gamebrew.org/gbhomebrews/144ptestsuitegb5.png https://dlhb.gamebrew.org/gbhomebrews/144ptestsuitegb6.png https://dlhb.gamebrew.org/gbhomebrews/144ptestsuitegb7.png https://dlhb.gamebrew.org/gbhomebrews/144ptestsuitegb8.png https://dlhb.gamebrew.org/gbhomebrews/144ptestsuitegb9.png == Changelog == '''v0.23 2023/03/03''' Highlights: * Health warning for tests that flash. * Backlight zone test has movement speed control for measuring afterglow time. * [NES] Input test (plug in controllers and see if they work). * [NES] Monoscope pattern by Keith Raney (khmr33). * [NES] MMC1 and MMC3 builds of the Suite and stand-alone ROMs of MDFourier. * [GB] Super Game Boy sound test. * [GB] Test surround sound decoder. * [GBA] Parallax scroll in Hill zone and Shadow sprite isn't glitchy anymore. * [GB, GBA] Add Donna background by Jose Salot.
