Hidden Menu and Games

An expanded version of the menu that lists five more games, which can be accessed by editing the value in the ROM at offset 0x7E530 from 00 to 01. The extra games are present on the multicart as well:

  • 14. Super Mario - Super Mario Bros.
  • 15. Super Mario 3 - Disappointingly not Super Mario Bros. 3, but rather a Metroid-themed hack of the first game. (Super Mario 2 is actually the fanmade romhack Super Ninja Acid Bros.)
  • 16. Mahjong 2P - Nintendo's Mahjong for the Famicom.
  • 17. Mahjong 4P - 4 Nin Uchi Mahjong, which as the menu name suggests is a four-player Mahjong game.
  • 18. Fruit Run - Actually an unlicensed game called Xiao Ma Li.
