gamozolabs - Fuzz Week Day 1

what is fuzzing?

fuzzing is automated testing of programs to gen crashes and stuff

pepsipu

from ram import RAM

# 0x00 -> add one to register 0
# 0x01 -> add one to register 1
# 0x09 -> register 0 = register 0 + register 1
# 0xde 0x?? -> load the value at 0x?? in memory into register 0
# 0xed 0x?? 0x!! -> store 0x!! at 0x?? in memory
# 0xee 0x?? 0xrr -> store registers[0xrr] at 0x?? in memory

# 0xde 0xde 0x00 0x00 0x01 0x01 0x09 0xed 0x00 0x01
