Notes:Roger Clemens' MVP Baseball (SNES)

This page contains notes for the game Roger Clemens' MVP Baseball (SNES).

Debug Menu code

Instead of having a stored pattern of controller button presses to compare against, this game uses a specific 16-bit value, much like Alien Storm for the Genesis.

When pressing A or Y on the title screen, a rotate left operation is performed on memory address 7E0FF1. If pressing A, the value is also incremented by one. These are the same operations used in NCAA Basketball, another game by Sculptured Software.

By pressing the right combination so that the final total is $956A, the debug mode is unlocked.

Here is a detailed look at the sequence AYYA YAYA YAAY AYAY:

A 0000 << 1 = 0000
  0000 + 1  = 0001

Y 0001 << 1 = 0002

Y 0002 << 1 = 0004

A 0004 << 1 = 0008
  0008 + 1  = 0009


Y 0009 << 1 = 0012

A 0012 << 1 = 0024
  0024 + 1  = 0025

Y 0025 << 1 = 004A

A 004A << 1 = 0094
  0094 + 1  = 0095


Y 0095 << 1 = 012A

A 012A << 1 = 0254
  0254 + 1  = 0255

A 0255 << 1 = 04AA
  04AA + 1  = 04AB

Y 04AB << 1 = 0956


A 0956 << 1 = 12AC
  12AC + 1  = 12AD

Y 12AD << 1 = 255A

A 255A << 1 = 4AB4
  4AB4 + 1  = 4AB5

Y 4AB5 << 1 = 956A
