I could say a lot of things, too, but Iām choosing not to. Because right now, whatās the point?
Yup, I figured it was going to be a possibility of semantics (and respective goals/definitions) with respect to the positions of our arguments. I can respect your position. Itās not one I would hold (and I could crack a joke here about how engineers, comp-scis, physicists and the like see the world, but Iām sure you know that one already).
Right now, the fact is that youāre having trouble getting any PSP title to run, and Iām currently not having that problem. I can run both Castlevania: The Dracula X Chronicles @ 60 FPS and Kingdom Hearts: Birth by Sleep at 30FPS. Pac-Man Championship Edition runs @ 60FPS. They launch, and run, without any hitches, problems or glitches that I can visibly detect right now without running a debug log and combing through the damn thing. On Lakka. 3DS and Dolphin (Gamecube) emulation right now doesnāt have a problem, and this is with the Intel integrated graphics chip on board. I sincerely donāt think RA/Lakka is the problem here. PSP emulation runs pretty smooth with the most recently integrated core (before, youād have a really good argument with the older PSP cores, they sucked, and that was with the devās own admission).
If youāre not willing to entertain Windows (donāt blame you and if you want a more appliance-like form factor, Windows isnāt going to cut it anyway), Retropie x64 is your only choice (currently as of the time of this writing) if you want PS2 with everything you have listed on Linux. An ideal choice for a Retropie x64-based machine, by their teamās standards, would be an old Alienware Steam Machine (think Alpha, but runs Steam/Debian instead of Windows). i5 or i7 (go with the i5, sweet spot for performance/price/hardware). Youād have a better chance with NVidia-based GPUs for this one. Since the Steam Machine already has built-in Bluetooth and 802.11ac Wi-Fi, youāll be fine with wireless controllers (hell, even the Wii U Pro Controllers work out of the box).
Corrupted ROM/ISO sets can be a huge pain in the ass. Iām suspecting your problem lay there (which more than likely, youāll probably have to grab some new ones or new copies of your good master set).
