物理接口[edit]
3ds游戏卡带拥有与DS和DSi有一样的物理接口。他们的区别只有3DS游戏卡带的塑料壳右上角有一个防呆槽,它能阻止3DS卡带插入到旧的Nintendo DS或DSi主机中。
即使去除防呆槽并把卡带插入DS或DSi主机中,系统也会拒绝检测卡带,并且不能显示标题图标。
引脚 | 名称 | 描述 |
---|---|---|
1 | GND | 接地。 |
2 | CLK | 时钟信号。DS/DSi游戏卡带频率分别为6.7MHz和4.2MHz,3DS游戏卡带高达16.6MHz(用于SPI和ROM传输)。 |
3 | NC | 未连接。可能用于编程卡(program card?翻译待查证)。 |
4 | RCS | ROM选择,低电平有效。送低电平开始传输ROM。 |
5 | RST | 重置信号。低电平有效。 |
6 | ECS | 存游戏芯片(Savegame chip)选择,低电平有效。送低电平开始存游戏SPI传输(savegame SPI transfer)。 |
7 | IRQ | 移除检测。 |
8 | VCC | 提供3.3V电压。 |
9 | DAT0 | 双向数据总线。 |
10 | DAT1 | 双向数据总线。 |
11 | DAT2 | 双向数据总线。 |
12 | DAT3 | 双向数据总线。 |
13 | DAT4 | 双向数据总线 /存游戏芯片上的NC/SIO3引脚。 |
14 | DAT5 | 双向数据总线 /存游戏芯片上的WP#/SIO2引脚。 |
15 | DAT6 | 双向数据总线 /存游戏芯片上的SO/SIO1引脚。 |
16 | DAT7 | 双向数据总线 /存游戏芯片上的SI/SIO0引脚。 |
17 | GND | 接地。 |
SPI闪存[edit]
目前为止,只有存游戏闪存芯片(savegame FLASH chip)被识别了。这块芯片被识别为0xC22211。JEDEC制造ID为Macronix,此外芯片标签为25L1001,与 MX25L1021E相符。
数据表位于:http://www.macronix.com/QuickPlace/hq/PageLibrary4825740B00298A3B.nsf/$defaultview/3F21BAC2E121E17848257639003A3146/$File/MX25L1021E%2C%203V%2C%201Mb%2C%20v1.1.pdf?OpenElement
http://www.beilenet.com/download/MX25L1021E,%203V,%201Mb,%20v0.01.pdf(old version mirror)
。不论如何,MX25L1021E不支持3DS用于与SPI闪存(SPI flash)交换数据的4位宽传输。因此,这可能是一块定制闪存芯片。
格式[edit]
Cartridge及系统更新存放在为此预留的区块内。 在ROM里,能找到小于1GB的CART_SIZE_MAX-( 0x280000*(CART_SIZE_MAX/CART_SIZE_128MB) )-0x2000000的更新区块。该区块为0x2000000字节。
通信协议[edit]
与DS和DSi游戏卡带相比,3DS系统与3DS游戏卡带的通信协议几乎完全改变了。
在第6个传输以后,命令从8 byte变为16 byte。可能使用了新的加密手段,比如AES CTR。 发送16 byte命令之后,卡带准备好并发送一个单字节数据0x01之前,数据总线一直为0x00直到。接下来是实际数据。每0x200-byte 实际数据块之后,是4-byte该字节块的标准CRC32码(未加密)。
下面是一个3DS主机给3DS游戏卡带的发送的命令样本:
