ZodTTD has updated gpSPhone, a Gameboy Advance emulator, for iPhone.

News about the upcomming release:

In preparation for updating the user interfaces on many of my projects this week, I had to update gpSPhone. By updating gpSPhone, I can now go ahead and use it’s new interface for my other emulators on the iPhone & iPod Touch such as snes4iphone, gameboy4iphone, etc… But in order to do that, I had to fix a nasty multitouch issue. It seems by enabling non-legacy user events in gpSPhone, the framerate took a massive 20% dive when more than one finger was touching the screen. Previously I was using legacy mouse events for iPhone dev. That was great until I noticed a mouseUp event wasn’t being called at the correct time. Well luckily by throttling a ’setNeedsDisplay’ call I have reducing the slowdown from 20% to less than 5% of the framerate. It’s now only slightly noticeable in the majority of games.

But I didn’t stop there…

I added an options menu with the following:

Skin Selection: Customize your controller overlays and select one of five choices here.
Scale: Choose whether to scale the screen to fullscreen or not.
Autosave: Save the state for the currently loaded game every 5 minutes.
Compatibility: If for some reason a game does not work, try enabling this settings. But beware as it will slow down games considerably!
Framerate Counter: Choose to enable the framerate counter. The target framerate is 60 FPS. It’s format is in: Framerate – Frames Drawn – Frameskip
I also fixed many bugs and added a few new features such as:

The gpSP game_config.txt is now being processed correctly. If you use a game listed within it, it will run much faster now!
You can now save to your currently loaded save state.
More than 300+ ROMs in a directory is now supported.
When missing or using an incorrect BIOS file, you will now get a textual message instead of gibberish.
The BIOS is now checked for in two directories: /Applications/gpSPhone.app/ and /var/mobile/Media/ROMs/GBA/
Some unnecessary code was removed and improved general performance of gpSPhone.
Many more minor tweaks and fixes.
Grab this public release of gpSPhone via my built-in Cydia ‘ZodTTD Public Source’ in the Games section!

Now we should be ready to update snes4iphone and gameboy4iphone (Gameboy and Gameboy Color emulator)… don’t you agree?
