you want perfect full speed an audio? the best if someone feels the nee dto do any more will get some *BASIC* PS1 homebrew. the N3DS simply-Lacks-Power. i've given you teh facts of Why it cant happen its not that people cant be bothered. its because theres nothing more to be done. performance and "usable" ("Just runs. Need sound disabled or sound is a mess, Innacurate emulation leading to visual and game bugs) has a hit a brickwall and and there wont be proper playability (Runs,boots, has sound, No glitches no bugs)
this is teh same tired argument your using many others cry about why no developer is doing more than a PoC for an N64 Emulator. Now.. if you want to see it done devs to do the impossible? *PAY THEM* Make it worth the fruitless and pointless time n effort to try and get any more performance out of PCSX-ReARMed on the N3DS the cost of a Raspberry Pi 3B a cheap MicroSD, and USB Power adapter is far less than its going to cost you to entice anyone to do what you want. (plus there smany many more emulators you can run on the 3B and if you get creative you can make a portable w/ a cheap LCD Display lil soldering and Button work, BOOM you got a deal. even i was able to cobble something together w/ a Waveshare 7' Display a friend's 3D Printera high Battery pack and my 8bitdo SN30 Pro.
ohh and btw Yea.. Bleem could of gone farther but Sony and thier lawyer's happened. so No Bleem isnt usable 100% it isnt the "Best" only the games it was listed for are garunteed to work anything else is a ticking timebomb of crashes glitches Lockups, freezes, VMU Corrupting problems waiting to happen. (even w/ the factor of Translation, the DC *Still* didnt have the power to drive much and would hit teh same brick wall. )
and you want to see your argument of "No its not about power?" fall flat? go ahead go grab some old gen2 i5 or i3 or early Phenom II by AMD Potato of a PC systems that can run SNES9X just fine but run Higan/BSNES(Accurate mode) and watch those pc's Crumble. the More cycle Accurate you go byte for byte.. bit for bit.. instruction set for set. the more overhead there is, and in turn more power's needed.
the 3DS wasnt *DESIGNED* for shenanigans like this in mind, Nintendo never built it w/ the best of hardware because it didnt need to.. and its Why they are so woefully under powered. hell even cheaper than a full decked out RPi3B, is a used PSP 1000 or PSP 2000(Slim) a huge chunk of the PS1 library works with patches ID Fiddling or the right converter in mind. otherwise as i said before Get a Moddable Switch, or a modern Android/iPhone and you got something that'll play everything
