There are so many programs available that it is difficult to give specific help.
However, we try and give extensive instructions in the User Manual that should help you get going.
Please note We have enabled external program loading on THE400 Mini so that the Atari community can have even more fun with the console!
Given the vast number of programs that are available, we cannot make any guarantees that they will all work or unfortunately address each individual problem.
However, there is a great deal of community support for THE400 Mini and our other products. We recommend reaching out to the various social media support groups, such as THEC64, THEVIC20 and THEA500 Mini Facebook group
