GameBoy Advance emulator for iPhone, Touch

Developer ZodTTD has released a new update to gbSPhone 0.0.5, a GameBoy Advance emulator for the iPod touch and iPhone. Although it is a small increment from 0.0.4, the developer said that it is a crucial update, introducing an improved graphical user interface and enhanced sound support – which the author credits to help from Nes.app creator NerveGas. Some performance fixes were implemented as well, through the default frameskip settings and some dynarec tweaks. The gpSPhone project is completely open source, and is available directly from ZodTTD's website.

Since gpSPhone is a third party application, users interested in running the software are required to 'jailbreak' their device, a practice that Apple has consistently disabled with new releases of the iPhone firmware.
