Homebrew RELEASE Development Thread - RetroArch libnx

If you want n64 and ps1 so badly then just use lakka...

No thanks... xD

 

[Deleted-351540]

No thanks... xD

I play them on my phone. Motorola Z Force + Moto Gamepad Mod FTW!

Edit:

Having an issue with setting the core directory on the nightly. Going to "Load core" shows no cores. So I went into the directory settings and set the core location as "/retroarch/cores/switch/" and then they show up, but quitting Retroarch and then reopening it puts the core directory back at <none>. Guess this is why they call it a "nightly", eh?

Second edit:

Manually setting it in the cfg file doesn't work.

 

[uyjulian]

No thanks... xD

Why not?

 

[Lunatics]

What exactly is needed to make these run and where do you put the roms? I downloaded VBA and Snes9x but I can't seem to find roms on them/don't know how to launch anything,

 

[huma_dawii]

So... I get this kind of weird bar that pixelates in a weird way the screen.... Any idea why?

I've been a LOOOOONG time lurker here at GBATemp, but the progress with this build of retroarch compelled me to finally make an account.

Thanks so much mx4w for all of your hard work! This is coming along amazingly!

Also, to answer a question...

m4xw told me on Reddit that this issue was caused by a mixture of being docked and the threading used by retroarch. I see this issue in just about every core I try while I am docked, but haven't had a chance to test it with the most recent nightly yet (I have just finished copying the files over to my Switch, but haven't yet tested it because my kid is hogging the TV).

Hopefully that clarifies WHY it's happening, at least.

Nice! waiting for results! I didnt notice before until i played in Dock mode!

If your experience with that tearing is anything like mine, you probably only noticed it while docked. I haven't noticed ANY tearing if I'm in mobile mode.

In case anyone's interested, I got ParaLLEl's threaded Angrylion working. The emulator runs about 20% faster than before. Of course, it's still far from fullspeed; it's still just a fun proof of concept. There are also a few new issues introduced in this build: it crashes the system in docked mode, enabling VI overlay causes the screen to render smushed to the upper half of the screen, and for some reason the new menu UI breaks the core completely, so it uses the old UI. You've been warned! I've attached the build to this post. I'm probably not going to bother continuing work on this core until we have hardware acceleration. At this point, the speed in this build is about the best we're going to get, so there's not much of a point.

Does this cause the battery issue?
No, this runs on Horizon.

OP, thank you for this ASTOUNDING app! Full screen NES on the go!

PS...if that's you in that orange and black chair, you're cute with gorgeous eyes!

Are u making sure you use my pthread wrapper funcs?

Speaking of which here is the FUSE sinclair zx spectrum emulator, recompiled in the stable retroarch branch

If controls do not work (which they wont at first): Load ROM>RetroArch Quick Menu>Controls>User 1 Device Type>Set to whatever joystick the game is asking you for. An on screen keyboard, atleast for the kempston joystick, is bound to select (-)

Awesome!

Been testing this and it works great.
Great job man - you've made me happy.
Only issue I had was I couldn't figure how to use sticky keys, like how to have it so Caps Shift remains down whilst I press another key on the virtual keyboard.

I've got most of the dev env setup myself and am keen to try to compile a Vice core for C64.
Are there any specific build instructions you used to build Fuse that I may need to consider?

Thanks again.

No, I actually switched to using the libnx thread stuff directly at some point when I was trying to figure out why it wasn't working, and I never ended up switching back. It would be pretty easy to switch back though, if I really wanted to.

 

[CatmanFan]

Any change of a C64 core (Vice)?

It won't compile thanks to the nuklear GUI stuff.
Used THIS repo.
Lakka does include C64 though, so...good luck on that

No sound in lakka (using internal speakers) makes it a no go for me.

At least there's still support for Bluetooth speakers

 

[thealgorithm]

Its too unwieldy and defeats the objective of portability. Hopefully there will be an internal audio fix soon (I guess there was some problems with voltages that blew the audio circuitry during testing)

Doesn't even run for me, just freezes

Try it again. I should add that to the list of bugs; sometimes it doesn't want to run and just locks up. Really strange stuff. Again, I'm not really bothered to look into fixing things when we won't be getting reasonable speeds anyways. If you're determined to try it anyways, try launching it a few more times and hopefully it'll work. Maybe try deleting the core options config file in the retroarch folder. That fixed the non-threaded version for me once when it stopped working.

Edit: I haven't had it lock up for me after many attempts, and I'm starting to suspect it's not actually a bug anymore in my final build. If it happens to you, make sure you aren't using core provided aspect ratio or integer scaling, as those will cause lockups every time.

Or just start it all over again but with the pthread wrappers.
Maybe that could work.

 

[m4xw]

New Salamander Nightlies incl. Overlay Support https://m4xw.net/nextcloud/index.php/s/QBpDpWxJeiGtD3w (Note: too lazy to build beetle etc, no CI), place overlays to /retroarch/overlays/<Core Name>.png, to disable them delete that file.
The "native overlays" will be fixed once I get more time, this will do. Snes9x2010 example overlay included

Edit: Thanks mod for cleaning up this mess lol

Not sure what you mean by "start it all over". It's simply a matter of swapping the libnx functions out for the pthread functions. Most of them do the exact same thing anyways. But there's really no pressing need to get a 5 FPS emulator working in docked mode anyways.

You should probably swap out the functions just for fun and see what happens.

will salamander also hurt our LCDs with burn-in like lakka?

Not really...


Unless you have maximum brightness, overlay enabled and no automatic sleep mode option!!

 

[baretbh]

what if they want to use this instead?
