Multi Bitmap Extractor
前言
最近在一个Discord群里跟一群大佬们折腾老的日系传统平台手机，有群友发现SH-03E这个MOAP(Symbian)设备使用的是eMMC，并且成功进行了Dump，历经一些研究，我和另一位群友一起研究了ROFS相关内容，成功解压了它的Z分区，Z分区中很多图符资源都是使用MBM(MultiBitmap/多重位图)格式打包并压缩的，需要使用塞班SDK里面的bmconv小工具来解压，但是其使用逻辑很奇怪，所以这次尝试写了一个图形界面。又由于群内很多人使用的是Linux，所以这个小软件支持Windows/Linux双平台使用。
注意
请使用ARCHIVE.ORG取得塞班SDK，安装之后在<安装目录>\epoc32\bin下找到bmconv的Windows和Linux可执行文件
