[CGB] SameBoy 0.15.8 06/11/2022

SameBoy jest emulatorem sprzętu Nintendo GameBoy, ColorGameBoy i w przyszłości GBAdvance (być może i coś już odpala, nie trafiłem jednak na nic, co dałoby się uruchomić) napisanym z myślą o Macintoshu, jednak i nam blaszakowcom dostała się wersja (SDL), którą z powodzeniem można używać.
