Jess Ragan has updated his Gameboy Advance version of the game Gorf.

From Wikipedia ( ):

Gorf is an arcade game released in 1981 by Midway Mfg., whose name was advertised as an acronym for “Galactic Orbiting Robot Force”. It is a multiple-mission fixed shooter with five distinct modes of play, essentially making it five games in one. It is well-known for its use of synthesized speech, a new feature at the time.

Gorf’s objective is simply to destroy all enemies. The player controls a spaceship that can move slowly left, right, up and down.

Release notes:

Yet more news on the GORF front. I’ve purged a few bugs from the previous build, and it should (should) work with 3-in-1 cartridges now. If you’d like to contribute to the project, I’d appreciate a list of what works with the game and what won’t. Here’s an early preliminary list, compiled from player input on the AtariAge and Denial web sites. The fix should resolve some of the issues people have had with their hardware, but not all. As usual, if you play the game on untested hardware, you do so at your own risk, but I’d appreciate any testing and status reports you’re willing to provide.
