== MBC3 mapper chip

MBC3 supports ROM sizes up to 16 Mbit (128 banks of #hex("4000") bytes), and RAM sizes up to 256 Kbit (4 banks of #hex("2000") bytes). It also includes a real-time clock (RTC) that can be clocked with a quartz crystal on the cartridge even when the Game Boy is powered down. The information in this section is based on my MBC3 research, and Pan Docs @pandocs.
