/*
* LibPSn00b Example Programs
*
* Teletype Example
* 2020 - 2021 Meido-Tek Productions / PSn00bSDK Project
*
* This example showcases the uses of tty through stdio facilities. If you've
* written text console applications before, this one is not too dissimilar to
* that. Escape codes for formatting and such should work as this is more
* dependant on the terminal program used than the PS1 console itself.
*
*
* Example by Lameguy64
*
* Changelog:
*
* May 10, 2021 - Variable types updated for psxgpu.h changes.
*
* April 23, 2020 - Initial version.
*
