Been away a while...whats new?

Ive been away for a while, and i’d like to get up to date with everything, so have a few questions…

Can I install RetroArch on an iPad Mini 2 - iOS 8.4 (jailbroken)? My main concern is the PSX cores, do they work?

PSX cores are working well. 1.0.0.1 is up on stock cydia repos, but nightly binaries haven’t been available on iOS for quite some time. If you have a mac, you can get Xcode and compile it yourself. Alternatively, a few people here have posted newer (than 1.0.0.1) binaries on the forums here.
