Total Funpak is an unlicensed multicart containing Pac-Man and three other games you probably don't care about.
Unused Menu#
The ROM contains two near-identical copies of the menu. The unused variant can be found starting at 0x3400. The only difference appears to be that The Penguin & Seal was originally going to be included instead of Duck Maze.
Unused Text#
ARCTIC ADVENTUREThis text string takes the place of "Duck Maze" on the unused copy of the menu.
Unused Graphics#
The menu graphics are stolen directly from Tengen's Tetris, a common source for unlicensed multicarts. Out of this graphic bank, only the ASCII characters and right-facing arrow are used.
The ROM also contains two copies of Pac-Man's CHR bank as well as those for the aforementioned Penguin & Seal.
