This OS was not created by the original user that made the original systems, and therefore this OS is not canon to the line.
Progresstendo Disk System is a system based on the Nintendo Famicom Disk System peripheral for the Nintendo Famicom (Nintendo Entertainment System outside Japan).
This system includes the three basic Progressbar gamemodes but with different names : Easy (Relax), Medium (Normal), Hard (Hardcore).
Progresstendo Disk System doesn't include mouse support; in fact, the Progressbar can be only moved using the in-game joystick, like in PB-DOS Shell
An extra gamemode can be unlocked by getting the Pro label in this system (10 levels) : Progresstrix, which is also available in PB-DOS Shell.
Obtaining Pro label unlocks also the Pattern Editor, which allows to create custom wallpapers with 16x16 patterns.

Progresstrix
Gameplay is similar to PB-DOS Shell Progresstrix, you must fill a line with the falling pieces. The Progressbar will be filled in base of blue and yellow blocks present in the filled line. Some pieces might contain a red block : if it touches an another block you lose a heart. Pink block deletes a nearby block.
