Huge thanks to the OP for dumping the disk and for all the other goodies he provides on a regular basis: http://www.atarimania.com/utility-atari-400-800-xl-xe-disk-emulator-routine_30963.html The whole combo is probably required to make the program work but it's great to have at least part of it archived

Thanks Jeff! Just added your copy: http://www.atarimania.com/utility-atari-400-800-xl-xe-backup-master-_31940.html

The OP will be highly disappointed if he thinks it is this game. The title on the Atari is called Wild West, not Dynamite Dan.

Don't forget Boulder Bombers (it was left out because I hadn't linked the game to the genre).

It would also be interesting to know what the absolute first third-party titles were. I'd put some money on the Sears / Image Computer Products games.

Thanks, please let us know how things go.

Thanks! Would you be willing to make a .wav file of the program or maybe lend the cassette so this can be done?

Most of the titles are just scattered in various PD collections, sometimes under different names.

OK, the Expando-Vision cartridge is this one: http://www.atarimania.com/game-atari-400-800-xl-xe-expando-vision-control-smoking-calm-nerves_1906.html It would be interesting to compare the two dumps to check whether the versions are exactly the same or see what prevents ianoid's ROM from booting.

Thanks! BTW, the year should be 1983, not 1985.

Are the two Color Sounds and Ripper 16K programs or actually 8K?

The Expando-Vision system lets you create subliminal messages using the hardware device which comes with the first cartridge: http://www.atarimania.com/game-atari-400-800-xl-xe-expando-vision-weight-control-exercise_1909.html The cartridges all boot straight away, the hardware device is only required when you create the messages. There are eight programs but only four have been dumped so it would be great if this turns out to be a title that is missing.

This is just fantastic, you undug some long lost prototypes! Thanks SO MUCH!

Incredible, thank you SO MUCH for doing this!

That would be great. Although the program is available, it hasn't been archived in its original format: http://www.atarimania.com/demo-atari-400-800-xl-xe-crystals_27840.html
