Emulation Center

zodTTD has been working again on his iPhone emulator, I’ll prolly use them soon when I got my iPhone but for the moment I can’t say much about how they work.

At the moment we have 3 updates from different emulators for iPhone, read the full article for everything!

1. Genesis4iPhone
———————

ZodTTD.com announces the public release of genesis4iphone v1.0.1. genesis4iphone is a
Sega Genesis and Sega CD emulator for the Apple iPhone and iPod Touch.
It is currently available via Installer.app courtesy of the Community Sources at ModMyiFone.com. It is also available
at the official ZodTTD.com repo. Manual downloads are being posted and will be available shortly.

I encourage everyone to join in on the forums here at ZodTTD.com and share your
genesis4iphone experiences by heading to the newly created genesis4iphone section:

2. Sne҂iPhone
—————–

sne҂iphone ҝ.5.0 has now been released to beta testers at ZodTTD.com. This build is very special as it marks what is soon to be a trend in the following weeks…performance increases! This is largely due to the great strides saurik made while updating the tools I use to develop with. With some fixes I′ve made plus the new toolchain, some users have reported a 50% increase in performance of sne҂iphone!

ZodTTD has also been working on getting sound introduced into sne҂iphone though it’s been an uphill battle. He can emulate and mix the sound, but for some reason it just outputs silence. More work is needed, but it at least is being worked on.

3. Ps×4iPhone
—————

In part with updating my older projects with the newer firmwares for iPhone/iPod Touch such as 1.1.3 and higher, I have released ps×4iphone Ҝ.2.0 publicly.
ps×4iphone is a Sony Playstation 1 emulator for the Apple iPhone and iPod Touch. It’s a large work in progress type project. It is based on the ps×4all project.
You can grab this release from the ZodTTD.com Public Installer.app repo source.

What’s new in Ҝ.2.0:

- Added support to firmwares such as 1.1.3 and 1.1.4.
- Compiled with saurik’s new toolchain.
- Fixed the detection of whether frameskipping can be used during certain frames within a game.
- Improved the dynamic recompiler code.
- Moved the BIOS location to /var/(mobile or root depending on firmware)/Media/ROMs/PSX/

This release brings up to 50% more performance than previous releases. Though going from 25 FPS to 37 FPS isn’t going to cut it, it’s still an improvement. Most games are running at about 20-30 FPS it seems. I’m not quite sure why the iPhone is running psҴall slower than most handhelds of equal or lesser raw CPU power. It may be due to the way the iPhone/iPod Touch clears it’s instruction cache via sys_invalidate_icache(…) or it could be due to the read speed of the ISO’s. Maybe both. Either way more work has to be done to see whats bottlenecking the iPhone and this application.

Feel free to discuss and ask questions about psҴiphone at the zodttd.com forums here:
