zodttd has udpated his port of MAME (Multiple Arcade Machine Emulator) for the iPhone.
Release notes:
I updated mame4iphone to version 1.5.0. It is now available on my Cydia Community Source repo allowing all people with Cydia, RockApp, or Icy to download it. I also updated the source which is available on my GitHub. I am not taking donations for mame4iphone, and want everyone to enjoy the 100% free release.
So what’s new in this release? While you should be able to notice more performance, I didn’t get to update things to the assembly CPU cores just yet. I did update it to the latest MAME4All v2.4 release by the talented Franxis. I also updated the iPhone/iPodTouch specific user interface to allow for even the entire romset to be loaded. This also fixed some bugs with some screen orientation plus scaling options to not render correctly.
There is a known issue where ROMs can not be switched mid-game. There is also no way to use save states due to the older version of MAME being used. Both of these issues occurred in v1.0.0 as well.
This should help ease the wait for my proper NeoGeo+CD emulator release, as a good amount of classic NeoGeo games are supported.
Give it a go, and hope you enjoy!
