The problem with Atlas
kefus - Dec 7, 2024

I can't figure out the Atlas program. This is my first time building home compilations, especially for Saturn. I haven't found any instructions online, so I'm asking for help here. Can anyone help with this topic?

Yes, I want to use atlas to put a couple of hombrew games.

Still I found instructions on how to create my homebrew disk, but I got stuck on the point where I need to break the game apart. I was planning to combine homebrew sonic x-trem and flashback on one disk. But how?

you have to follow this :

How to customize:
1. create temporary folder "myAtlas"
2. create an ISO:
2.1 create folder "cd" in "myAtlas" and
put the 16 files and folders of Atlas in:
0.bin (required)
ABS.TXT
ATLAS.CEL (your custom)
ATLAS.MAP (your custom)
ATLAS.PAL (your custom)
ATLAS.TXT
AUTOSTART/
AUTOSTART.INF
BIB.TXT
CREDITS.CEL (your custom)
CREDITS.MAP (your custom)
CREDITS.PAL (your custom)
CPY.TXT
FLD_KNL.BIN (required)
README/
README.TXT (your custom)

2.2 download and extract Mkisofs.exe and Cygwin1.dll
into "myAtlas"

2.3 create file "MAKEISO.BAT" into "myAtlas":
mkisofs -quiet -sysid "SEGA SATURN" -volid "SaturnApp" -volset "SaturnApp" -publisher "SEGA ENTERPRISES, LTD." -preparer "SEGA ENTERPRISES, LTD." -appid "SaturnApp" -abstract "ABS.TXT" -copyright "CPY.TXT" -biblio "BIB.TXT" -generic-boot ip.bin -full-iso9660-filenames -o myAtlas.iso cd

2.4 add game data
for each game add data into "cd":
(see below how to create)
"GAMENAME" <- folder with all files on game CD
"GAMENAME.IPI" <- game ip.bin
"GAMENAME.CEL"
"GAMENAME.MAP"
"GAMENAME.PAL"
"GAMENAME.SPR"
"GAMENAME.TXT"
"GAMENAME.AIF"
2.5 put Atlas' "ip.bin" into "cd"

I followed these instructions, but it was the last point that confused me.
1. Do I need a separate folder for each homebrew?
2. where to get files like GAMENAME.CEL, if they are not in the game (for example, the same iso sonic Xtreme).
3. Is game ip 0.bin?

After a week or two I figured out disk creation again, and the program works, but creates an empty disk
