Each standalone profile records where its version is read: the source at its pin (clk 2026-07-23-136-g9020107, shadps4 0.20.1 WIP, eden v0.2.0-401-g26a03d2), the APK, binary or archive read (kind package), or, where no reading can be made, kind unverified with the reason: a host the tools cannot read, a forge gone or not answering, no build recorded as read, a pin on another branch. Those keep their value, unconfirmed.

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.
