If you grew up in the mid-2000s with a flip phone, a Sony Ericsson, or a Nokia brick, the phrase "stupid zombie 240x320 jar" might trigger a deep, nostalgic itch. To a modern gamer, it sounds like nonsense. But to veterans of the Java ME (J2ME) era, those four words describe a beloved sub-genre of mobile gaming.

The most famous title matching this description is likely (or its clones like Zombie Crisis ). However, the "240x320 jar" search usually refers to the GameLoft or Glu Mobile knock-offs from 2006-2010.

If you find a working copy today, don't expect The Last of Us . Expect a green-skinned pixel idiot walking into a wall while you laugh and reload. That’s the charm.
