notes: |
|
|
Autch's SDL port of Naoyuki Sawa's P/EMU, with two commits by YonKuma
|
|
that add game controller input and a quit hotkey. AmberELEC builds this
|
|
revision and installs piemu with the mkpfi and pfar tools built from the
|
|
same tree.
|
|
ref: AmberELEC packages/games/emulators/piemu/package.mk:5-6,19-29
|
|
|
|
The emulator reads one file, piece.pfi, from its working directory: a PFI
|
|
header with the SYSTEMINFO block, then the flash contents at the stored
|
|
offset. A missing file, a signature other than PFI1 or a SYSTEMINFO of the
|
|
wrong size stops it.
|
|
ref: piemu.c:5-20, piemu.c:25-45
|
|
|
|
That image holds the P/ECE kernel, its file system and the installed
|
|
programs. AmberELEC's piemu.sh builds it for every launch in /tmp/piemu:
|
|
mkpfi writes a fresh image from the kernel update image all.bin in the BIOS
|
|
directory, then pfar adds the .pex program, its .sav file or the files a
|
|
.pfs list names. A .pfi game never starts: the extension test lacks its `$`,
|
|
so the image is not copied into the working directory.

note: "mkpfi checks the \"Piece Kernel Program\" signature at offset 8, writes the boot vector 0x00C02004 into sector 0, leaves sector 1 blank and copies the file from sector 2. Called without -2mb, it builds the 512 KB flash layout of factory units."
