/* LibPSn00b Example Programs
* Part of the PSn00bSDK Project
*
* RGB24 Example by Lameguy64
*
*
* This example demonstrates the 24-bit color mode of the PS1. This mode is
* not practical for gameplay as the GPU can only draw graphics primitives
* in 16-bit color depth so this feature would normally be used only for
* fullscreen graphic illustrations or FMV sequences.
*
*
* Changelog:
*
* May 10, 2021 - Variable types updated for psxgpu.h changes.
*
* May 3, 2019 - Initial version.
*
