I've found a bunch of glitches in my Game Boy games over the years. Some of them have been helpful. I discovered one glitch in Super Mario Land 2 that allows me to take items out of levels and into others (even the invincibility star). You can even take a bubble from the Hippo Stage and enter another level with it! I've included a picture of a glitch I found in the GB version of Mortal Kombat 2. Does anyone play Game Boy or Game Boy Color? If so, what games do you own?
