I have a bunch of disks with games. I remember the games were OBJ
files, but how do we execute an OBJ file? What are the commands to
load OBJ files from a disk drive?
Thanks

Object files? From DOS iirc, do you have a copy of 2.5?

The easiest option is to install a game DOS (like S. Bauke's NDos) on the
drive, and then simply boot from the disk.
So long,

If it is an 800/400, remove any carts. If it is an XL or XE with stock
OS, hold down the option key while booting a disk with DOS on it. IIRC
From the menu choose 'L for load binary, give it the full file name
i.e. GORF.OBJ, and it should run if it was properly saved.
If it wasn't properly saved, you may have to choose a run address with
'M option. First guess would be it could be a cart image with A000 for
the run address.
There are other things you can do, like a binary save 'K with run/init
address to patch those in and make it a load and go file if that is the
problem. Maybe menu option 'B for run cart would work.
Most of us can piece together what the thing should do from a few bytes
perpended and/or appended to the file.

OK, You've hooked the 1050 to the SIO
port. You turn the computer on. If the computer
is a XL/XE, you hold OPTION until the disk
starts booting.
Now, you get a DOS menu screen, with DOS
2/2.5. Or you get a game screen if the disk is
a game menu disk. If a game menu disk, it
is simply hit the letter of the game you want.
But probably it is a DOS 2/2.5 disk, and you
get the DUP menu. Pick 'L' for load file.
Uh-oh, you don't know what is on the disk.
You hit 'A' Return Return to get a directory
listing of D1: Now you can see the files on
the disk. Now type 'L' Return and type
D:FILENAME.EXT (PACMAN.OBJ eg.).
and the game will load and run.
Some games require a game load disk, but
that should be on your disk. If you get
the BASIC READY prompt when you boot,
you didn't successfully hold OPTION on boot,
try again.
If the game doesn't run, or the screen goes blank,
it may be a menu disk loader program. A very
few programs will require BASIC, so you don't
hold OPTION for those.

Ive printed your answer out and put inside the Atari box so I never
have to forget. Thanks a bunch!
