PS3 version has a number of bugs, Overall its great but its not maintained very well by the official team these days for the PS3 Port.
There is some menu items that will freeze when accessed on the PS3. usually it just toggling an unsupported feature for the platform.
Some cores included have never worked and will not work on the PS3 (in current form), yet they keep being included when they are unusable.
after v1.0.0.2 builds are not very well optimized for the PS3 IMO. They are usable and you can enjoy them after but you will get freezes here and there and see some things not work., Which really annoys me and cant understand because the project is suppose to be about versatility and i think it puts a black eye on that, The thing is these issue are always well documented and they dont seem to want to take care of it and also seen developer submit fixes for them to only get ignored. Its odd they keep rolling out so many new versions that have flaws and are annoying to use.
