15-in-1 (KS-122)

15-in-1 is yet another unlicensed NES multi-cart from Taiwan.

Sub-Page#

Notes

Unused Graphics#

Unused bigger versions of the stars used for the menu border.

Unused Text#

Bizarrely, two of the text strings on the internal game list were seemingly replaced at the last minute. Pinball erroneously added a space in the title, while Sky Destroyer replaced Ma Chiang. The unused strings can be found with the rest of the used menu text starting at 0x24FA in the ROM, while the replacement strings can be found starting at 0x3001.

Source Code#

Beginning at 0x3010 is a partly corrupted chunk of the menu's source code. A comment near the beginning dates this code to May 7, 1987.
