Hello I have a raspberry pi with fba libretro 0.2.97.37 or 0.2.97.38 and retroarch 1.3.6 or 1.3.4 psikyo game work very fine with fba libretro 0.2.9.34 but with fba 0.2.97.37 and higher , I have bug sounds, and a catastrophic frame rate.

Only Striker 1945 work fine.

Bug games : Battle K-Road Daraku Tensi The Fallen Angel Dragon Blaze Gunbarich Gunbird Gunbird 2 Lode Runner The Dig Fight (Double écrans) Samurai Aces Sol Divide The Sword of Darkness Space Bomber Striker 1945 II Striker 1945 III Tengai

Why ?

barbudreadmon commented 7 years ago

What's your raspberry pi ? 1 ? 2 ? 3 ? Also, what distro are you using ? retropie (from my experience and a few issues reported here, there are speed issues on retropie) ? recalbox ? another ? Last few things i don't understand : those games are slow ? are crashing ? have glitches ? and what do you mean with "Tengai (FBA 0.2.97.30)" ? And what do you mean by "fba libretro 0.2.9.34" ? fbalpha2012 ? Be precise if you seek help please.

Hello @barbudreadmon sorry for my english , I am French.

with raspberry 2 on recalbox OS 4.x and raspberry 3 with recalbox 4.1.

recalbox 4.0.0 use fba libretro core (0.2.97.37 but same pb with 0.2.97.38/0.2.97.39)

glitches like with with fba libretro core (0.2.97.38) like this post on forum : http://libretro.com/forums/showthread.php?t=6555&highlight=psikyo tengai game works well on fba 0.2.97.30 core.

the others are big problem, audio bug and slow.

I know about those glitches, they got solved 2 months ago with https://github.com/libretro/fbalpha/commit/8e3768c7bde9f60baefd4b3697ebc6d9e0b65735 .

Looks to me like some of the games you talk about are related to the https://github.com/libretro/fbalpha/issues/99 issue, which i hope @AkimanBengus will be able to solve

About the speed issues, try with those settings in /boot/config.txt :

dtparam=audio=on dtoverlay=sdhost,overclock_50=84 arm_freq=1350 gpu_freq=550 over_voltage=5 sdram_freq=550 sdram_schmoo=0x02000020 over_voltage_sdram_p=6 over_voltage_sdram_i=4 over_voltage_sdram_c=4 gpu_mem=384

and try running (perhaps recalbox already do this, but do it anyway, without this, your raspberry could downscale your cpu frequency) :

echo "performance" | sudo tee /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

before launching a game. Perhaps it'll still won't run at full speed (fba is not targeted at arm@1.35Ghz, so it's a normal thing), i intend to try finding a few speedhacks when i got time to spare, but right now i'm more concerned with crashes and other real issues like inputs not working.

If you don't know how to do what i told, ask recalbox, not me, i don't know how recalbox deal with those settings, i'm not a recalbox user.

Don't come back before updating your software/config, i have a bad personality and i'm quite pissed off when people report things that got solved 2 months ago.

I added a core option to switch between "fast" and "accurate" mode in SH-2 based games (psikyo, cps3 and some kaneko games). Choosing "fast" mode should fix speed issues in those games by skipping timers, but i can't do anything about the other issues those skipped timers will produce (i know some kaneko games will have sound issues with that hack).

Since your other issues were either duplicates from https://github.com/libretro/fbalpha/issues/99 or already solved, i close.
