Released in 2006 as part of Nintendo's forgotten bit Generations series, Soundvoyager is a game that's literally meant to be played with your eyes closed.
Present within the game's data is a build date.

Interestingly, graphics for a completely different game remain buried within the ROM. They're graphics for Neopong, a currently lost build of the game Boundish that was only released in Japan.
Partial reconstruction of the title screen graphics:
Similar graphics can be seen at 0:23 in this trailer for the unreleased "Digitylish Series" that contained Neopong as part of its lineup. It could be that Neopong was a working title for Boundish and the name was going to be re-used for the unreleased international version.
There's also a copyright date for 2005, one year before any of the bit Generations games were released:
Some strange "cell" icon. This appears to be a rough, early version of the menu icon used in Boundish for "Pool Flower":
Icons which depict the stick-figure characters seen in Boundish:
A set of letters. The font doesn't match the stylistic lowercase font used in Soundvoyager:

Soundvoyager also contains miscellaneous graphics relating to this early build of Boundish:
Debug Mode Remains
When viewed in a hex editor, a string can be found that describes a "DBG MENU" along with numerous menu options such as "MAP SELECT", "CALIBRATION" and an entire menu of maps that otherwise do not appear at all during normal gameplay. There aren't many menu screens to go through in Soundvoyager, so these strings must be pointing towards a hidden or inaccessible debug menu.
