Getting the best PSP experience on a Pi 4

RVA-818X-LAYstar

I turned off all the Anisotropic filtering, texture enchancements, and other extra graphic options. Made a pretty big difference.

Game I was testing was Guilty Gear XX Accent Core + R.

Went from random slowdowns during certain animations (no real rhyme or reason). To a locked 60FPS.

Other games like Ridge Racer and Burnout though I can't get much higher than 30-45FPS. They hover and dip around that area.

This is on an overclocked RPi 4.

@rufficuss I got it runnig, but i am missing something very important: the text.
Seems to be a general problem (see "Lunar") with the font the PSP used.
I allready asked here for hints but sadly got no answers :/

@zering said in Getting the best PSP experience on a Pi 4:

Has anybody been able to play Lunar : Silver Star Harmony with text displaying correctly?

Edit : Never mind, replacing the files under bios/PPSSPP/flash0/font with original PSP font dumps and reinstalling PPSSPP from source did the trick.

@zering thank you for this advise
i allready saw this footer and tried to download the linked font-package.
I had no luck, i could not unpack the file because of a corrupt archive.
But anyhow: does that only work with PPSSPP or also with lr-PPSSPP?

Zering

@sirhenrythe5th I only got it to work with PPSSPP, as performance on the libretro core is vastly inferior I don't use it.

There has been an update to PPSSPP recently.
One of many improvements is this one here:

Numerous fixes to the builtin fonts by nassau-tk

So there might be a built-in solution in future version-updates.

@sirhenrythe5th The last source update I did for PPSSPP (about two weeks ago) broke a few games (GTA Vice City Stories no longer booted), so I reverted to a pre-compiled binary. Is this update more recent?

I updated both last night both work, however lr-PPSSPP has developed a strange lag issue. The game appears to have frozen for a few seconds but the audio still plays, then the screen catches up. Most games are unplayable.

PPSSPP seem unaffected by this.

This is specific to the ppsspp-dev build that is inside the RetroPie-Extras GitHub https://github.com/Exarkuniv/RetroPie-Extra

In the most recent dev builds, Retroachievements now work on PPSSPP.

So if anyone wants to play with achievements on for the PSP but the retroarch core is too slow on pi3b/4 then it could be worth looking into this.
