AmberELEC builds this\nrevision and installs piemu with the mkpfi and pfar tools built from the\nsame tree.\nref: AmberELEC packages/games/emulators/piemu/package.mk:5-6,19-29\n\nThe emulator reads one file, piece.pfi, from its working directory: a PFI\nheader with the SYSTEMINFO block, then the flash contents at the stored\noffset. A missing file, a signature other than PFI1 or a SYSTEMINFO of the\nwrong size stops it.\nref: piemu.c:5-20, piemu.c:25-45\n\nThat image holds the P/ECE kernel, its file system and the installed\nprograms. AmberELEC's piemu.sh builds it for every launch in /tmp/piemu:\nmkpfi writes a fresh image from the kernel update image all.bin in the BIOS\ndirectory, then pfar adds the .pex program, its .sav file or the files a\n.pfs list names. A .pfi game never starts: the extension test lacks its `$`,\nso the image is not copied into the working directory.\nref: AmberELEC packages/games/emulators/piemu/bin/piemu.sh:10,22-54\n",
