Bounty for Beetle PSX dynamic recompiler claimed

[Deleted User]

It's finally being claimed. The claimer is pcercuei, whose dynarec has been officially used in libretro for a few months now. He is also working on porting it to other PSX emulators.
What the PSX dynamic recompiler does:

Instead of emulating the PlayStation CPU by interpreting one instruction at a time, a dynarec (dynamic recompiler) would take large blocks of PlayStation CPU instructions and translate them all at once into a block of instructions your computer's CPU natively understands. The translation process (recompilation) is complicated but the resulting native code runs much faster than directly interpreting PlayStation code. It basically means that the emulator will run faster on weak computers.

Was there none before? Was the one before not available for widespread use?

While dynarec is good stuff does it really matter for most things nowadays? I guess there are handheld ports though.

I looked on https://www.bountysource.com/issues/48048939-dynamic-recompiler-895-bounty and in turn on https://github.com/daeken/beetle-psx-libretro but did not see what license it falls under.

@the_randomizer is probably dancing the Charlston now.

I completely forgot about that to be honest

So now what?

Maybe now a psx emulator gets ported to the Nintendo WII U?

Can we have a good psx emulator with this good stuff in a New 2dsxl? or maybe old 3ds?

Some of this is already in libretro. I´m no developer, but yeah,why not?

In their webpage retroarch on 3ds the s(psx rearmed) have dynarec.But only works in some few titles in a new2dsxl even with the correct bios it seems sluggish. It would be different if we have beetle emulator in 3ds..

The N3DS is 804 MHz, it's also old tech, I doubt they can squeeze much more out of it.

PSX is MIPS
3DS is ARM

not easy to get running on 2011 tech TBH

You have a valid point,mips have more perfomance because the psp have similar processor.

I mean, it CAN run PSX, just...not well

yes i know arm its a different processor and programming for it needs to develop more time in the New2dsxl

I know you said the New2dsxl its ancient tech but comparing to a psp,have better specs.For example maximum processor for the psp slim 330 mhz vs new2dsxl 800 mhz.

Right, but I'm just saying

Nice.
Took a while, but finally the dynarec is complete.
Now remains the work of porting it to other architectures, and depending on the performance, it'd be interesting to see how well Beetle's dynarec fairs agains Rearmed's on consoles like the Switch.

I would love to see Beetle PSX with 2x resolutions and PGXP working on the Switch at smooth framerates.
