从这份基板资料中可以看出：SYSTEM12的CPU Board全部相同，TTT的游戏启动程序在Main Board上的Intel E28F016S5 TSOP40 上存储有Main program ，Fujitsu 29F400TC SOP44 存储有 Sound program ，在GFX ROM Board（也就是游戏ROM板）64M MASK SOP44和Fujitsu 29F016 TSOP48 芯片ROM中存储有游戏镜像，下载街机板的游戏镜像将游戏镜像只要按照表中所示的一一将文件刷入相应的SYSTEM12空ROM，就可以破解了，但要注意用的SYSTEM12主板和ROM的一定要是同区版，比如美版配美版ROM,具体可以网上查！！
