Hi, I resquest some game genie codes for easier level selection,
these below are the standard codes

stage select (press at the title screeen)
  • stage 2: A, B, A, A, A, Up, Down, B, Start.
  • Stage 3: Select, A, B, B, A, Select, Down, Up, Start.
  • Stage 4: Right, Right, Down, Down, Up, Up, B, Select, Select, Start.
  • Stage 5: Down, Right, Left, B, A, B, Select, Select, Start.
  • Stage 6: Up, Left, Left, Right, B, Select, A, Select, Start.

should be cool reduce these strings of inputs to 1 or 2 in a way more memorizable,, for example

2: select, up, start
3:select, down, start
4:select, left, start
5:select ,right, start
6:select, a, start
