100 emulator names the two platforms run had no profile, so their packs carried nothing for them. Each was read from the platform's own launcher or scriptmodule: the same program as an existing profile takes the name in cores:, a different build gets its own profile read from that version, a launcher or self-contained game goes to remove_cores, and the rest are new profiles written from their source or shipped binary. The files they need that the collection lacked are collected from the upstream distributions. Bungie and splitwolf trees are read by path and stay out of dedup.

PC Engine emulator by David and Cedric Michel, distributed as a closed
|
|
Windows binary. The build read is pce.exe 1.1.3, dated 17 June 2008, sha1
|
|
b58461eca2614326bd776d12b01c4ab2e7d0f579, the copy RetroBat installs as
|
|
magicengine (version 0.08.06.17).
|
|
|
|
RetroBat starts it as pce.exe "<rom>" with the emulator folder as working
|
|
directory and runs it only for the pcengine and supergrafx HuCard systems.
|
|
The generator writes pce.ini (paths for cheats, screenshots and
|
|
saved_games, video, language) and the controller section, and sets no
|
|
system ROM. A HuCard carries its whole program, so this route reads the
|
|
game file, pce.ini and the games.idx index the program keeps in its own
|
|
folder, nothing else.

supergrafx)
|
|
|
|
pce.exe is a loader. 0x426ec0, called from 0x401712, decrypts about
|
|
1.2 MB held in .data at 0x4484c0 (0x2491e eight-byte blocks of a SAFER
|
|
style cipher whose exp and log tables sit at 0x448220 and 0x448320),
|
|
inflates it with 0x426b00 into a 0x1f8d50-byte buffer, applies the
|
|
relocation list that follows and jumps to offset 0x1000. That routine was
|
|
run under an x86 emulator to obtain the program image, and the addresses
|
|
below are addresses in that image relocated to base 0x10000000. The pce.cfg RetroBat ships is the binary keyboard and
|
|
gamepad layout (ME10CONFIG) and names no file.
|
|
|
|
System cards are four paths of the [pce] section, system_card_1 to
|
|
system_card_4, defaulting to syscard1.pce, syscard2.pce, syscard3.pce and
|
|
ge.pce (0x100118a7-0x10011910, setter 0x100094e0, getter 0x10008b00).
|
|
default_system_card picks the card a CD boots with: 0 automatic, 1 to 4
|
|
one of the four files, 5 to 7 Magic System 1.0, 2.0 or 3.0, a system card
|
|
BIOS built into the program. Automatic means the third path, syscard3.pce.
|
|
The chosen file goes through the HuCard loader (0x10082630, 0x10082250)
|
|
with no size or hash check, and when it cannot be opened the boot falls
|
|
back to Magic System 3.0 (0x10007752-0x10007f79, 0x100826b0). A card
|
|
named on the command line after -cd is loaded the same way without that
|
|
fallback. The internal HuCard database names the dumps it recognises as
|
|
system cards by CRC32: 3f9f95a4 (1.0), 52520bc6 (2.0), 283b74e0 (2.1),
|
|
6d9a73ef and 2b5b75fe (3.0), 51a12d90 (Game Express), which drives the
|
|
title shown and not the boot (0x10142e40-0x10143c20). arcade_card only
|
|
turns the Arcade Card hardware on and loads no file. CD saves go to
|
|
backup.dat and backup.idx, written by the program.
|
|
RetroBat does not route pcenginecd to MagicEngine today, so these files
|
|
only matter when it is run on a CD by hand.
