Alot of people experience this man, why else would Clydefrosch have posted that.
Dbz legacy of goku, minish cap and boktai. Probably more. I think the issue is on larger sd cards.
i am aware of that issue, but as far as I'm aware, it is always fixed with the right reformatting of the sd card. dont ask me exactly why these things correlate though. i too have played minish and at least played around in boktai without screen issues.
The PSP has perfect PSX emulation but the 3DS has none at all (at least none that would be considered playable)
But the 3DS has a more correct resolution (400x240 so 320x240 games can be displayed without scaling for best clarity), whereas on the PSP you either get slightly blurry scaling or black bars on all sides.
I think the 3DS does a better job at older systems, in particular the PSP seemed to be lacking when it came to SNES emulation, and GBA wasn't the best either (mGBA on 3DS should be better), at least on a n3DS.
Also 3DS has a better game library.
If good PSX emulation is important to you then PSP is the obvious choice.
guys, you dont have to split hairs over the terminology, the truth is, the psp can play ps1 games and the 3ds only barely can play some at barely tolerable speed.
the psp emulation starting with snes is wonky at best, requiring loads of settings to be checked through and its still far from perfect for more demanding games. if you turn off sound completely, its usually good, but you probably want sound. the o3ds plays all but the fx games fullspeed (as so often, sound isn't always perfect, but its still better than on psp) and the n3ds just plays the entire catalogue.
gba required you to use 3 forks of the same emulator to have most games run playable on psp.
o3ds and n3ds have injection to run all games perfectly (once you disable the blurr effect nintendo thought should be brought over...), but gba emulation unfortunately isn't perfect either.
mgba works, but sound can reach earsplitting screech levels and speed will dunk all the time, because they try to go for accuracy instead of fps.
retroarchs gpsp shows that it can run all gba games perfectly if you're willing to ignore accuracy, however, whoever ported that core introduced a bug into his dynamic recompiler that will crash the emulator randomly, within 3 seconds or after 8 hours (usually within 10-30 minutes).
emulationwise, you're much better of with the 3ds. hands down.
decide based on wether or not you want psp/psx or 3ds games.
