PSP homebrew developer Zx-81 is at it once more, and he's bringing us some sweet, sweet retro action on the go with his latest version of PSPColem, the ColecoVision emulator for the Sony PlayStation Portable. This update brings the PSP homebrew emulator to version 1.1.0.

Armed with a number of improvements, this updated version now also has a neat feature of saving and displaying thumbnails for each of your save states. Handy, for those of us who like to save multiple times, like just before a boss fight or the point of a game where you broke your own best score.

Let's take a gander at the changelog and see what's new from the last version.

What's new in version 1.1.0:

• Display and save thumbnail images for each save state
• New graphics
• Option to prevent the blue led to be displayed when L or R are pressed
• Option to display frame rate
