The Underminer dropped us a line just now, informing us that he's released version 1.00 of his Galactic Breakout homebrew game for the PSP.

As he mentions it, the game now has a lot of improvements, including the inclusion of 21 mp3 tracks, 70 levels, 2 new bonuses and blocks, graphic effects, and a core speed of 333mhz, which he says eliminates the crackling sound. He also mentions an extended profiler feature, which we'll leave up to him to explain:

A cool feature that I built in is the extended profiler. When no profile exists (when you first start the game), it will first search the memory stick for existing (demo) profiles and request to copy it. If the users wants to create a new profile the PSP's nickname is used.

We advise you to go ahead and check the readme as well, because it lists the directions for installing the game and using it. You can also visit the Galactic Breakout website linked below for additional information. For now, enjoy the game!
