PSP Nightly discussion thread

Since 2016-03-21_RetroArch version, PSP freeze starting RA and crash.

Hello friends first of all I am RGM, I give thanks for this magnificent project for PSP and PS Vita.

Now the emulatoes are great, I have only a problem with specifically catsfc with the ROM Super Mario All-Stars and Super Mario All-Stars + World controls in the menu match but during the game dont work, other problem is in some games like Rockman an Forte enemies by touching the character disappears.

One last question, there is a possibility of adding core FBA or MAME version for PSP?

Thank you.

Sorry for my English I speak Spanish.

Thanks for the responses friend.

I hope to continue to update this great project.

OK friend some questions?

How I can disable the frameskip for the character does not disappear when you touch an enemy in catsfc and some colleagues from other forums I was told that the games have sound sfx are slow and hear something wrong, do you think that in future versions can be improved in these problems.

And one last question in relation to the FBA or MAME core, it would be very difficult even emulate older games like Toki, Simpsons, Data East, Toaplan, etc? as FBA4PSP from Ibecilyne as that stalled in development.

Greetings and thanks for the answers

Catsfc fps is better but still screen tearing problem.

Will PSP version fix it? by the moment in the nightly only RA starts but is not the same for the cores, that it has issues with zipped roms.

Is it possible to change the confirmation button from O (circle) button to X (cross) button?

In your retroarch.cfg, swap the values for “menu_ok_btn” and “menu_cancel_btn”

Sorry if this has been asked before, but what clock speed does the PSP run at for Retroarch? Is it the full 333mhz? Does it depend on the core?

Also, I’ve been using the 1.3.0 stable build because Quicknes and Gambatte both crash on my PSP-1000 in the later ones. Do these cores now require the 64mb ram of the later models?

I recently fired up a nightly and I have a strange problem. With the Picodrive and tempGBA cores if I play a while (say longer than 20 min, I haven’t tested precisely), then I push the music button to bring up the retroarch interface the whole thing just freezes. I have to push the ps button and kill it.

Also, I was playing Phantasy Star Collection on tempGBA for about 2 hours and saved multiple times, and none of them went though. I didn’t realize this until loading retoarch again and finding an ancient save greeting me.

Dunno about the first one, but for the second one, RetroArch doesn’t write saves to disk unless/until you exit “cleanly” (which usually means via the ‘quit retroarch’ option from the menu). If you exit by hitting home or killing the process or whatever, the file will never be written.

There’s an option to write it to disk every few seconds but it requires threading support and I don’t think the PSP port has that.

That does perfectly explain the lost saves. Would it be possible to force Retroarch to write through when writes happen as an option? I’d be willing to wait the few seconds for the safety.

That’s a more complicated issue than it seems, since a lot of systems use SRAM for scratch RAM and write to it constantly. We’d have to add heuristics to try and figure out when it was a real write and when it was a scratch write, and those heuristics would inevitably have edge-case fails and those edge-cases would lead to constant read-writes that would drastically shorten the lifespan of solid-state storage, in addition to being an I/O bottleneck.

Thanks for the explanation. Guess I need to figure out why RetroArch is freezing then.

It sucks to have to do it like this, but the easiest solution is to take a savestate any time you do an in-game save, since savestates are written immediately. Even if you lose the SRAM, it’ll come back when you reload the state and all will be well.

Do not work kernels nes that on stable assemblies and at night! It is necessary to put the old kernel 1.3.3

is retroachievements compatible with psp retroarch version?

I’m sorry if I’m an idiot. But why are the downloads not .pgk files? How do I install it on my PS if this is the case? Thanks!

Hello. I’m using Retroarch latest nightly on PSP e1000. My issue is whenever I load a game the PSP simply turns off. It loads the core just fine but turns off 4-5 seconds after I load content. What seems to be the issue? TIA

Hello, i’m using Retroarch 1.9.0 and tried several nightlies on my PS Vita, several cores crashes completely Retroarch, like FBA 2012, Stella, Stella 2014 and Picodrive (trying 32x roms), and i must delete Retroarch.cfg to have it working again.
