TxtWriter is a ... text writing program. Using the virtual keyboard, you can type out a message that can then be saved to a CF card in a device such as the GBAMP. Button assignments for shift, backspace, space, and return make typing a little easier and are paralleled on both sides for left- and right-handed people.

You choose your own filename for the text files, but it only saves it to a folder named "TXT" in the root directory.
