Hi cooky069, what i can tell from my own experience, and having tried a couple of differnt brands + speeds, this has to do with the card speed, because of the swap handling the emulator does, wich seems to be pretty heavy. I don’t know that brand Integral, maybe the speed advertised doesn’t match class 10 ? It’s the only thing i can think of.

Hi, the freezing thing was sd card related. I tried IO Timing method from 1 to 3 making no difference at all. I’m using a 32gb sd hc1 class 10 now and it works perfect, once in a while it would freeze for 0,5 seconds, almost nothing. It happens on my cellphone too.

Funny thing is i have the isos on the old 32 gb sd class 4 via pendrive/usb adapter, so it’s related to how the emulator manages memory, specifically swap or some sort of cache the must be read from main sd. Also the size of the iso doesn’t affect performance

Hope it clarifies things for everybody.

Tried both, the standalone seems to be slightly better. Tried today with an 8gb sandisk ultra class 10. I works way bettter, still freezes once in a while but less frequently, and sometimes yellow light it’s not blinking so it’s not entirely an I/O factor it seems but pi’s processing power. I guess this emu needs more work but impressive none the less. If i had more time i’ll dig into it to see if i can improve it.

I have it working perfectly, even Demon Front, you must have something wrong with your roms. When you run the game and the console shows up hit a or b button and a menu shows up, choose second option wich is for select emulator for that rom in particular, maybe choosing another fba version? retropie comes with 3 fba versions, lr-fba-next is what i find more friendly with newer romset and specially pgm. Good luck!

Hi! i tried a couple of different settings and still freezes for a couple of seconds here and there.

Then i tried something different: used an usb flashdrive with a 2gb sd card and pointed the roms dir en es_systems.cfgt to the mounted sd.

Emulation Station recognized it and listed the roms correctly. Run some roms and it freezes but the light that blinks it’s still the green one that’s beside the red power led on the pi. I don’t know , does that light blinks when there’s *any* I/O activity or just the “main” sd card? If it’s just the sd-card then the emulator is using some kind of caching/swapping system i guess, otherwise it doesn’t make any sense.

What’s your cpu/gpu mem sharing config?

Excellent!,thanks for the info!!
My pi2 is even more overclocked than that but the thing here is something related to I/O operations.

I’ll try tonight with those settings and let you know. I friend lend me an 8gb class 10 sd card, will try with that too and finally i have a spare external usb hardrive, will see how that works.

Great New!!! Thanks for sharing! So i guess it’s a matter of sd card speed/quality , i should get a faster one if a want better psp support. Thanks for testing buddy!!
Cheerz.

[repuken2]

Tried changing many settings , i think the most I/O related ones, like CacheFullIsoInRam and SeparateIOThread, FastMemoryAccess and FuncReplacements.

Now that i see it, i didn’t change IOTimingMethod , i’m gonna tune that one and see what happens.

Anybody tried it? ppsspp or lr-ppsspp ?
Any experiences to share? Cheerz.

[repuken2]

I’m pretty much sure it’s the sd speed wich causes the I/O issues, still i’d like somebody to confirm he/she has it working okay with a faster card. I’d love to have this system working properly, it seems to work very well at least with the 2D games. Metal Slug 6 and Metal Slug XX …

Did you try all the 3 cores? the gles version works quite well for me on some games like Mario Kart. Other games are slow, happens the same on my cellphone on android wich is more powerfull than the pi2 so i guess it’s a matter of the emu improving in the future.
