This game has unused graphics.
The Zone 60 is one of several Zone branded Plug & Play systems that copied the design of the Wii while forgetting to copy anything else worthwhile from it.
An unused .bmp file containing JungleTac's logo can be found twice in the internal ROM at
0x3450B80. An identical graphic is also known to be present in the Wireless 60 and the Vii's internal ROM, as well as in both dumped multicarts released for it.
