Note: While the Concerto is being actively manufactured and developed with firmware that needs a bit more maturing, a "Concerto" folder has been setup which contains files designed to be as compatible as possible with the device.  It may contain just header modifications neccessary to ensure best compatibility with the device or additional changes.

Proper full standard ROM builds and/or headers are provided in their typical appropriate residing places.

Change Log since HHDP_20160928:

With the exception of maybe a handful of ROMs, all files have had their respective header updated.  Just about all have received an update to their embedded game name, modified from a generic "My Game", file path, or some other misinformation.  Many needed hardware flags corrected, and there have been external file name updates as well.

"Trak-Ball" and "Paddles" support has been added to the header.  Games that support paddles optionally, have at least two different files, more if NTSC and PAL versions exist.

In addition to the above, the following is also noteworthy:  

NEW: Asterix Quest (Hack)

NEW: Desert Falcon (Prototype)
[Harder Sphinx Bosses and HSC Support]

NEW: Hearty Manslapper

NEW: Realm of No, The (Book Cart)

NEW: Roof Pooper

NEW: Serpentine

NEW: Sprite Demo

NEW: Sprite Demo 2

UPD: 3D Maze Game

UPD: 7800 Utility Cart

UPD: Jr. Pac-Man

UPD: Ms. Pac-Man 320 (Sound Updates)

UPD: Rescue on Fractalus (Proto) (Correct Header)

UPD: Scramble (Bug Fix and Side Columns Added)
