Would you be able to check whether the two cartridges below work with your system? They crash on a standard computer.

How many ways can I say stupid, not to you leech, but to anyone fool enough to pay $2,500 for that cart. There's no way that it's worth anywhere near that, even from a collectors point of view.

But that auction comes with free First Class shipping.  That's always the best way to send overpriced cartridges to another person, amirite?

Or try it on an 800 (or 400 upgraded to 48K), booting while pressing FIRE on a joystick plugged into port 3.

Works like a breeze on atari800 with this patch hack.

Edit: when a test runs, you can press the following keys:

 

OPTION - sometimes displays four graphics 0 lines at the bottom with extra information

SELECT - stop test

S - swap colors of object 1 and 2 (red and green)

T - toggle visibility of object 1

B - toggle visibility of object 2

You're right, it works fine on OS-B systems. For some reason, I thought that wasn't the case.
