About LLE emulation

I would also like to add, from my results of the search, he has deceased.

That's horrible

There's nothing really to develop for LLE. It works fine as it is, and if we'd like to get all games working perfectly, we could simply improve non-HLE areas, to increase speed and RSX emulation accuracy.

So is that it really? Execute some cellSpursFile.elf or whatever and you will have The Last of Us running with some improvements to RSX? Can't be that "simple" surely? (What I mean is that looking at the current state of rpcs3, is that really the only big thing left now?)

There are likely still PPU and SPU emulation accuracy problems, possibly preventing modules and games from being emulated properly. One example is likely, that GTA V with LLE seems to fail, due to SPU emulation inaccuracies. RSX emulation seems to currently be the main thing blocking most of the games from working. Nekoteki could probably correct me or elaborate on the subject of the various backend problems.

Of course, the ultimate goal would be to have everything HLE'd, so everything would work out of the box, and you could modify tons of settings, maybe even add graphical improvements, higher internal resolution, etc.

I don't know inner workings of PS3 architecture but I don't think you need HLE for things like higher resolution, antialiasing or even texture replacement. Dolphin can do all of that with LLE and many other LLE emulators can increase resolution too.
