Wondering what else ZodTTD's been up to, aside from creating PlayStation, GBA, and Gameboy emulators for the iPhone? How about one for TurboGrafx-16, or as the dev calls it, temper4iphone? ZodTTD has announced that work is well underway for this new homebrew project (formerly known as Temper) which was originally conceived by Exophase for the GP2X.

ZodTTD in turn got permission to port Temper over to the iPhone and iPod Touch, which is now being released to the dev's Beta Test team. Now, if you're not a member of the coder's beta team (and hence have no access to the homebrew), we've got something else lined up.
ZodTTD's also posted a video demonstrating how temper4iphone works. It's a long way from actually running it on your iPhone, but at least you'll have an idea of what to expect when the emulator finally goes public. Enjoy the clip, and drop by again when we run into any more updates.
