It ignores the logo in cartridge header and will display it's own even if no cartridge is inserted.\n* Runs too fast (~19.2% faster), as some other clones do\n* Screen has significant motion blur\n* Appears to have trouble powering on if connected to another powered-on Game Boy via Link Port\n* Cartridge slot does not line up well with the case \n\nThere are markings on the cart slot (\"GF Logo\") which may link it to \"Gang Feng\" / \"Kong Feng\", the makers of the \"GB Boy (Pocket)\" and \"GB Boy Colour\" clones.\n\n# Maxstation Boot ROM\nThe [boot ROM](/bootrom/) was dumped with help from [nitro2k](https://blog.gg8.se/wordpress/) using the BennVenn [clock glitch](https://blog.gg8.se/wordpress/2014/12/09/dumping-the-boot-rom-of-the-gameboy-clone-game-fighter/) method.\n\nThe boot ROM is largely identical to the [DMG one](https://gbdev.gg8.se/wiki/articles/Gameboy_Bootstrap_ROM) with a couple differences:\n* Loads it's scrolling logo from the bootrom (itself) instead of from the cartridge header region\n* Uses different logo data (\"Loading...\")\n* Performs the logo and header checksum calculations, but skips the failure lockup tests\n\n\n# Pictures\n\u003cimg src=\"/images/maxstation_gameboy_clone_boot_logo_data.png\" width=\"300\"\u003e\n\n\u003cimg src=\"/images/maxstation_gameboy_clone_boot_logo.png\" width=\"300\"\u003e\n\n\u003cimg src=\"/images/maxstation_gameboy_clone_pcb_back_cpu_marking_22C309CH.jpg\" width=\"300\"\u003e\n\n\u003cimg src=\"/images/maxstation_gameboy_clone_shell_back.jpg\" width=\"300\"\u003e\n\n\u003cimg src=\"/images/maxstation_gameboy_clone_cart_slot_GF_logo.jpg\" width=\"300\"\u003e\n\n\u003cimg src=\"/images/maxstation_gameboy_clone_pcb_front.jpg\" width=\"300\"\u003e\n\n\u003cimg src=\"/images/maxstation_gameboy_clone_screen_back.jpg\" width=\"300\"\u003e\n\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbbbbbr%2Fgameboy_clone_maxstation","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fbbbbbr%2Fgameboy_clone_maxstation","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbbbbbr%2Fgameboy_clone_maxstation/lists"}
