Did you do ASM coding?

To tell you the truth I scanned the internet for alternative Game Genie codes and found these:

OPXIVXSU - floating bricks

IEXKTGLA - Start with 6 lives

SNSKXUNN+LESKULPA - Players move at 3X normal speed

SNSKXUNN+ZESKULPA - Players move at 2X normal speed

ELKITLEY - Monsters bump you instead of killing you

GPUKOAZX: Super jumping power

GKUITZXZ+TKUIYZPZ+KSUSAZSZ red push blue

SNSKXUNN+ZESKULPA - double speed

AAVKEVZZ+AANIZSZP - controllable jump

PEXGIGIA - skip intro

GKUITZXZ+TKUIYZPZ+KSUSAZSZ- push the other player

GKUITZXX+TKUIYZPA+KSUSAZSZ: One player can kill the other

USEKYETO - Game Boy Version

OKEIPGVS: Infinite lives

ATKSALAZ: Become invincible

AEXKTGLA: Start with 1 life

IEXKTGLA: Start with 6 lives

AEXKTGLE: Start with 9 lives

So I used the Game Genie Guy Utility to encode these codes into the Ice Climber rom

ELKITLEY

PEXGIGIA

AAVKEVZZ

AANIZSZP

IEXKTGLA

SNSKXUNN+ZESKULPA

GKUITZXX+TKUIYZPA+KSUSAZSZ

Finally I used the IceClimberTextEditor to change some text.

If anyone wants to take it from here, be my guest. I have kinda reached the limit of my hacking skills.
