Abdessamad Derraz 8b203e397c chore: mark what the new profiles' installs bring
The profiles written for RetroBat and RetroPie were checked the same way: UZDoom, LZDoom, SRB2 and AdvanceMAME data ship with their releases, RetroPie installs the shareware Doom, Quake III and Wolfenstein data, the Aleph One scenarios and 4DOS beside the ports it builds, RetroBat installs Jynx's ROMs, and Recalbox's uae4all core comes without the AROS ROMs.

Patrick Aalto's x86 DOS emulator for the Raspberry Pi, freeware and closed
source. Profiled from the binary RetroPie installs,
files.retropie.org.uk/archives/rpix86.tar.gz (sha256 8591b715f7c5...ad328d),
an ARM EABI5 executable whose banner reads "rpix86 (Raspberry Pi x86
emulator) v 0.19" with "BIOS date: Jun 28 2015". The BIOS, VGA and sound
emulation are inside the binary. Its strings name no ROM, font or patch
file, only the shell below, /boot/config.txt (overscan defaults), the
input and serial devices, and the log and screenshot files it writes.
C:\ is the directory given with -d, the working directory by default
(usage text). The emulator looks for its shell as C:\4DOS.COM or
C:\4DOS\4DOS.COM. When neither exists it stops with "Unable to find
4DOS.COM command interpreter (shell)" and offers to fetch it with
"wget http://rpix86.patrickaalto.com/4DOS.COM". RetroPie runs the binary
from its install directory and unpacks
files.retropie.org.uk/archives/4dos.zip (sha256 801441f3f65e...5b636a,
4DOS 7.50 from JP Software) there (scriptmodules/emulators/rpix86.sh).

note: "Same bytes at rpix86.patrickaalto.com/4DOS.COM, the URL the binary downloads from, and in RetroPie's 4dos.zip. Read from the emulated C: root, not a BIOS directory. The author's rpix86.zip and rpix86.tar.gz hold the binary alone, and RetroPie unpacks 4dos.zip into the install directory."
