Saturn存档格式(BackUPram)
BUP位于0x00180000处，大小64K。因为此处地址空间是16位的，但所用的SRAM芯片是8位的，所以偶
地址数据悬空(读出为FF)，奇地址才是有效数据。所以BUP实际大小32K。
BUP中的数据以64字节为一块来组织。一共有512个块。前两个块系统保留。块0是标志，
"BackUpRam Format"重复4次。块1全0。
其余的块，头部4个字节是标志。0x80000000表示一个save的开始。0x00000000表示普通块。块的空闲
与否需要解析每个save来判断。
save开始块结构:
00: 80000000
04: 存档名，11字节。
0f: 语言标志。
10: 存档注释，10个字节。
1a: 存档日期编码，4字节。
1e: 存档字节大小，4字节。
22: 存档所占块列表。以0000结束。开始块用完则延续到下一个块。需要跳过块的前4个字节。
注意，如果20指示的存档大小可以放在开始块之内，则不需要占用块列表了。
块列表后面就是实际存档数据了。块列表不包括开始块。
=========================================================================
自定义存档格式(SaroSave)
前64字节是文件头，接着64字节是块占用位图。
32K的存档，块大小是64字节，共512个块，可用64字节的位图表示。
存档大小加倍，则块大小也加倍，这样位图大小不变。
存档开始块占用一个块。存档数据占用的块也用64字节位图描述。数据位图不包括开始块与位图块。
若是32K存档，位图占用开始块后面的块。若是大于32K的存档，位图位于开始块内部。
文件头
00: "SaroSave"
08: 存档字节大小
0c: 块大小
0e: 空闲块数量
20: 游戏ID
3e：第一个save的块编号
save开始块结构:
00: 存档名，11字节。
0c: 存档字节大小，4字节。
10: 存档注释，10个字节。
1a: 00
1b: 语言标志。
1c: 存档日期编码，4字节。
3e: 下一个save的块编号。
