Homebrew Retroarch Emulation Thread (Nightly Builds Included)

One little weird thing on ps1 emulation. In the Legend of Mana Title Screen fps is a stable 59.887 (or whatever fullspeed is). But the audio stutters anyway. Why is that? When I skip the intro movie on Legend of Mana the game crashes unfortunately.

This ps1 emulator is nearly playable. Just some speedboost, 20-30%, and many games would be fullspeed!

Can pcsx_rearmed take advantage of NTR's overclocking ? Seems it would help....

It already takes advantage of the N3DS's potential clocking. I also wouldn't really consider it overclocking as the N3DS's CPU was designed for it.

 

[JackyD]

Thanks. Yea, i tried it at a few clock speeds and it definitely is taking full advantage.

 

[SLiV3R]

Is there any other alternative that could be done so the ps1 boost in speed? I mean things aliaspider could work with?

 

[sj33]

The only thing that could really be done is implementing GPU acceleration. I can't see that happening though because it's a large undertaking - probably a little bit beyond the scope of porting libretro.

Perhaps it is a large undertake... But if that would mean ps1 games in fullspeed, I hope someone thinks that it would be worth the trouble

Is GPU acceleration=hardware acceleration?

 

[sj33]

Yeah. The only emulator on the 3DS I'm aware of that uses GPU acceleration is blargSnes.

The issue with regards to Retroarch is it would have to be core-specific -GPU acceleration for PCSX wouldn't work for any of the other cores.

Gpsp keeps locking up and forcing a reboot after about a minute of use. On 9.2 n3DS with 10.4 emunand. Using latest nightly CIA. Doesn't happen with gambatte or pcsx.u

Edit: seems to only happen with an idle fix patched ROM of Drill Dozer

Tested some more, it also happens with the normal Drill Dozer ROM and the 3DSX build, but not when playing any other games. Does anyone have an earlier nightly I could try? And could someone test whether Drill Dozer crashes on their system?

how Pepsi Man m Crash 3 and Crash CTR and Digimon rumble arena on PS1 emulator?

Is there supposed to be screen tearing still in the Picodrive emulator? It's really jarring. (Using N3DS Reinand 10.4)

there's screen tearing in several emulators I think. the last build I noticed to not have this (by default?) is Nov23.

Do you have Vsync enabled? I don't have any tearing, though I'm on o3DS. If that doesn't work, you can try out GPU hard sync.

Do you still possibly have the .cia build to that file? If not, I suppose I'll just have to rough it until a fix occurs.

GPU hard sync doesn't fix anything. V-sync is enabled. However, Bilinear Filtering does stop the tearing but I don't like the smeary vaseline effect that occurs.

[Goloki]

I'm getting some very localized... "tearing" in the gPSP core, on the upper left section of the screen. But only with the GBA core and performance is perfect otherwise. Is anyone else experiencing this issue? I'm running a N3DS with 9.2 sysNAND/10.4 emuNAND and ReiNAND 3.2.

Thanks! I'll see what happens.

 

[SLiV3R]

I have a lot of screen tearing as well on genesis emulation. Mega Turrican for example. But I haven't noticed any screen tearing on PocketSNES, fceumm, ps1 etc.

@sj33 I think MasterFeizz is also working on hardware acceleration on his Quake 1 port.

 

[ShadowOne333]

That N3DS cover is amazing!
Would you mind to tell me where'd you get?

Oh and BTW, I'm also experiencing tearing in the upper part of the screen with gpsp in a N3DS XL.
Haven't checked other cores yet.

 

[Rob Tree]

There seems to be a screen tearing bonanza all of a sudden.

As I said before HW Bilinear Filter fixes the tearing but at the cost of smearing vaseline all over the nice pixely graphics. The Nov build didn't fix the issue, unfortunately.
