Bonk's Adventure is a platform game by Hudson Soft/Red, starring a double-jumping pain in the ass deformed midget caveman, as well as being released late in the console's lifespan.

Hidden Menu

To enable a level select/sound test, press and hold Down, Left, A, B, Select, Start while the title logo scrolls onto the screen. Select switches between level select and sound test mode, Left and Right change levels, Up starts the selected level, A and B change the sound number, and Start plays the selected sound.

Unused Graphics

Graphics for some kind of debugging function can be found in the CHR. The NAME/TYPE/ITEM labels and box cursor seem to imply that these belonged to a level or sprite editor (perhaps similar to the one present in Super Bonk). Unfortunately, none of the associated code seems to remain in the ROM.
