My Arcade V Gamer 220 in 1

Developers: Various
Publishers: My Arcade, dreamGEAR
Platforms: Unlicensed NES, VT03
Released in US: 2016

SourceIcon.png This game has uncompiled source code.
CopyrightIcon.png This game has hidden developer credits.
SoundIcon.png This game has unused sounds.

The My Arcade Gamer V 220 in 1 Handheld is an interesting device: It reuses the body of one of dreamGEAR's earlier handhelds while redoing the internals.

Unused Audio

Stored in the PCM data between the menu music and the cursor selection noise is... a clip of Ylvis' The Fox (What Does The Fox Say?). May be used in a different variant/firmware, but is totally unused here.

Unused Source Code

At 0x7BE2E3 there is a big snippet of unused source code that might go to a game either in the console or to another one of the DreamGear consoles.
