Homebrew developer ZodTTD is ending the year with a bang as he's released v1.2.0 of his newest emulator project on Apple's iPhone and iPod Touch.

There are a significant number of changes since our previous coverage of gpSPhone, including improved save state support, added initial support for zipped .gba files, and increased performance among other things.

Here's the complete changelog of the latest version:

Changes 1.2.0:

• Added initial support for .zip archived .gba files. The .zip must ONLY contain a single .gba file.
• Added support for volume changing via iPhone and iTouch volume controls.
• Added option to add a new save state file or overwrite the previously loaded one.
• Improved save state support. No more crashes and save states are timestamped. Compatibility remains for old version save states.
• Improved suspending/resuming of the emulator.
• Improved button input routine. Now combo buttons work better.
• Improved the default skin/overlay to support better left and right button input.
• Fixed a bug causing the emulator to crash when headphone jacks were inserted or removed during gameplay.
• Fixed a delete ROMs bug.
• Fixed a bug in the controller skins that made L+R go to the menu screen.
• Moved the unscaled GBA screen to the top of the actual screen.
• Increased performance.

For those of you interested in trying out this nifty emulator, don't forget to have the correct gba_bios.bin file installed for this to work. After installing it, you must set the gpSPhone file's permission to 0755, otherwise it won't run.

You can also take a look at the Readme.txt file that goes with the application for  more detailed, step-by-step instructions on how to install the app.
