Me and a few others have been considering porting PCSX2, the PS2 emulator for x86-64, to ARM so it can run on Android/iOS (eventually, hopefully, at some rate). Before doing that I asked PCSX2 devs, but none of them had much to offer on ARM or porting a recompiler, and this is not something I have experience with.
So, I decided to ask those who have successfully done this ... the Dolphin team. What steps or what kind of general outlook was considered for this pretty difficult task?
I mean, was the recompiler code just passed along and switched up to ARM equivalency?
How much optimization was needed to get it going right?
How much rewriting was needed, if any, of the code, like the GUI, GPU stuff, OpenGL for ES, etc.?
Hope this question isn't taken the wrong way ... just open to a friendly discussion here about the process of porting to ARM/Android, etc.
