A handheld system featuring, across three different menus, 2,666,664 DIFFERENT GAMES.
...Which is actually 62 NES games repeated over and over, because of course it is.
Unused Graphics#
These can be found in ROM addresses $6010, $4010, and $02C010 for the 777777-in-1, 888888-in-1 and 999999-in-1 respectively. The background pattern table also carries copies of the arrow in the menu that are completely unused.
Several animation frames of a completely-unused Crash Bandicoot are in the CHR data of all three menus. Here are two sprites that could be put together without any guesswork.
While all three menus have the same font, all of them do not use the ampersand and apostrophe symbols. The 999999-in-1 doesn't use the X graphic, while the 888888-in-1 doesn't use Q, U and V, and the 777777-in-1 doesn't use Q, V, W, and Z.
It appears as though the 777777-in-1 was going to have snowflakes falling from the sky; this effect does not happen at all in the released compilation.
Also unused is the top of the house, overwritten by the cartridge's ID.
