This is a template designed for developing NES (Nintendo Entertainment System) games using the MMC3 memory mapper. The MMC3 mapper is one of the most advanced mappers used in NES cartridges, allowing for extensive bank switching, IRQ handling, and more complex games that go beyond the limitations of the basic NES hardware.

2024年7月21日 · iNES mapper 4 (MMC3)提供了一个方便的方式来令帧内改变PPU实现“特殊效果”像在NES游戏中的分屏显示滚动。 而不是使用0号精灵的命中去计时让你写PPU硬件，使用IRQ就可以令CPU有效的通过帧工作，而不是浪费时间获取0号精灵的命中标志。

MMC3 可谓是最开始几个Mapper中相当占分量的Mapper. MMC3是少数可以触发 IRQ 的Mapper之一. MMC6也是用同一个mapper编号, 内部逻辑大致相同. 目前实现到第一个测试的测试12: "RTI RTI不允许执行主线代码" ... 我™... 这些测试ROM就是搞事. four 1 KB banks at $1000-$1FFF; 1: two 2 KB banks at $1000-$1FFF, four 1 KB banks at $0000-$0FFF) MMC6 的M位是指是否使用PRG-RAM. +- Nametable mirroring (0: vertical; 1: horizontal) IRQ闩锁, 用于指定一个重载值.

您计划将什么连接到 mmc3？ 在 TI EVM 上、如果将 JAMR3子卡连接到 EVM、则可以通过 MMC3访问 SD 卡插槽。 子卡具有连接到 MMC3接口的 SD 卡插槽。

6 天之前 · The Nintendo MMC3 is a mapper ASIC used in Nintendo's TxROM Game Pak boards. Most common TxROM boards, along with the NES-HKROM board (which uses the Nintendo MMC6), are assigned to iNES Mapper 004. Some less common MMC3 boards required alternative iNES mapper implementations: This chip first appeared in the fourth quarter of 1988.

2024年1月8日 · 文章详细介绍了mmc3芯片在nes游戏卡带中的内存映射机制，包括prgrom和chrrom的银行选择和内存布局。prgrom有模式0和1，模式切换影响8kb内存区块的映射。chrrom的内存映射受a12信号反转影响，导致不同页面的选择。

2022年3月17日 · For example, Nintendo World Cup appeared on two boards that extend the MMC3 in this way: one with SMB1 and Tetris and one with Super Spike V'Ball. This same structure occasionally shows up in ordinary single-game mappers: Bandai's Oeka Kids games, Namco's Devil Man, several other Namco games, and a …

2021年5月7日 · The MMC3 is the most advanced of the most commonly used mappers, but it's really just a mapper that allows you to use larger PRG- and CHR-ROMs. Notably it has a scanline counter which allows you to do screen splits (raster effects) much easier than without it.

2013年9月7日 · MMC3 can be used for 16K MMC1-style bankswitching, since it has two 8k pages that can be switched. It cannot do 32K bankswitching at all. MMC3 does let you use CHR-RAM, but you have to initialize the pages to map 0-7 over the 8K range.
