I assume I do that in Altirra under Configure System. I did and took a screen shot and I still get the same error.

I am using the Altirra emulator and I am trying to play House of Usher by Crystalware. I get the game to load, get the title screen, there is a running countdown to begin the game and then it crashes and I get this error message. I believe the files are actually good files - I downloaded them from the atarimania site - and I am thinking that the problem is on my end and my own ignorance. Am I doing something wrong or is there a setting I need to tweak in order to get House of Usher to work properly. Thank you so very much to anyone who can help. I will include a snapshot of the error screen or crash screen

So I have an Atari 800 XL and I ordered the Ultimate Cart from the link you provided but this cartridge appears to be too small to fit the cartridge slot in the back of my Atari800XL. Could this be an XE cartridge and they sent me the wrong size? The slot on my Atari800XL is much bigger. Oh man

Can I order an Ultimate Cart still for my Atari800XL? I hope we are still able to do so

Is the ultimate cart still available for purchase I would like purchase one. Thank you
