Homebrew Retroarch Emulation Thread (Nightly Builds Included)

[Pickle_Rick]

Actually I've kept gpsp running a game overnight with dynarec off. It was still running in the morning. The older ninjhax cores were unstable iirc. Every core crashed at some point.
Also the retroarch team have found a way to get dynarec working on pcsxrearmed on hbl as well as picodrive in hbl. So keep a look out for that. 3dsx with dynarec enabled woot. But they said gpsp is not well used and is lower priority

I just tried it five minutes ago and it crashed playing Yoshi's Island with dynarec off.

Are you sure it's not an emulator compatibility issue rather than a dynarec issue? Because I have been playing a heavily modified version of pokemon and it's been running fine for hours.

Works fine on my psp running gpsp.

You do know the psp uses a newer version of gpsp right? Not all version are identical between consoles.
Iirc there are 3 different versions of gpsp for psp

Well that depends because the libretro one is a fork and still gets updates every now and again. Also, it used to work on older versions of RA so it was broken at some point. I used to play Yoshi's Island all the time with ninjhax until it started crashing. (Also, it doesn't crash on other platforms that have the gpsp core.)

It is possible. Changes made can actually break compatibility with a single game only or multiple games. Does it crash with every game for you? Cause if it's just yoshis island that sounds like a game compatibility regression.

Yeah eventually, but Yoshi crashes really fast. You can barely play through a level.

That really sounds like dynarec is on tho. Did you disable it in quick settings them completely close out of retroarch via rgui and not the home button?

Yes, it's disabled. I've even restarted my 3DS and it still says disabled.

 

[the_randomizer]

No, gpsp still crashes.


All games ran full speed on the n3DS even without dynarec. They still do, it just crashes now. Anyway gpsp and the 3ds patches are open source and on Libretro's github.

Damn, that sucks.

 

[Rahkeesh]

I just crashed Yoshi's Island on the 3dsx version after the first area, impressive.

I guess this is more of a game compatibility issue, this is the first one I've hit without dynarec. But more are surely out there.

Edit: if you think saving is causes crashes, you might try converting the ROM to use SRAM with GBATA. Flash saves don't seem to be supported at all (Mario v Donkey Kong, Final Fantasy Tactics, don't crash but refuse to save) but converting them to SRAM allowed them to save.

 

[Clydefrosch]

i don't know what you guys don't get about random crashes.
I've played final fantasy 6 for hours without a crash before, and I've also played it with almost 50 crashes per hour. it is random.

also, i can't take anyone serious who says gpgp on n3ds runs acceptable without dynarec. it doesn't. just like mgba doesn't. not even close.

It does though. Even the title screen on Yoshi's Island runs full speed with it disabled. But yeah the crashes are random.

Ok, I think we've all concluded gpsp isn't working right.
No developer is looking into this issue, at this moment.
To be able to solve it, you'll need some specialized knowledge about the GBA, gpsp, and probably the 3DS itself.

Maybe try to discuss a possible solution?

A few possibilities are:

• Learn C and try to fix it yourself.

• Wait until someone else learned C and fixes it for you.

• Start a bounty to get someone, who does have the skill and interest, to fix it for you.

O, and last but not least..

• forget about gpsp and hope mgba will reach the level you wish (and gets included in retroarch again).

This is a discussion thread for RetroArch. Talking about gpsp is entirely in topic and OK to discuss.

 

[MrHuu]

O by all means, please continue your discussion. Sorry to interrupt, it was about to get interesting!

Some guys have already taken note, and found a couple of things which could be causing the dynarec crashes in an Issue on RetroArch's Github page.
https://github.com/libretro/RetroArch/issues/8750

It seems to be caused due to some condition which checked for old methods of launching homebrew, and said method seems to affect almost all cores which relied on dynarec for good performance on 3DS (like PicoDrive, PCSX Rearmed, gPSP)

I noticed, @Vague Rant is doing some nice work there! But, please correct me if i'm wrong, isn't this issue is related to dynarec not being enabled in the first place?

When it's enabled, it still crashes.

 

[Rahkeesh]

Yeah I think Vaguerant is working on getting dynarecs to work as .3dsx, so you don't have to install .cia to use them. It's not going to fix any crashes unless they were specifically related to running as a .cia for some reason.

 

[NotReallySteve]

Does mame 2003 plus work yet?
Does dynarec cause crashing in psx stuff? I thought I had that enabled and seemed to have stuff working okay, but then all I've really tried is some shmups (absolutely not fussed about anything the psx is doing with polygons tbh).
