[quote name='icruise']I guess the question is, do you have a way to get your downloaded PS2 save onto a PS2 memory card. If so, you can get the save onto the PS3. If not, I don't know. You could try putting it on a memory card (like an SD card, memory stick, etc) and copying it to the PS3, but I kind of think that won't work.[/quote]
i have been trying to figure this out as well.. and no you cannot do it like that...
for instance, gamefaqs.com has saved games in max and codesaver formats etc.
there is a program to convert it to other formats... im curious which format extension does the memory card use? is it .npo ? or something else
far as i know there are people working on converting the formats to .psv format ( which is a ps2 saved game on ps3 ) but the problem is that the ps3 digitally signs the saved games, so if you try to edit the ps2 file, it becomes corrupted... so perhaps in time this will be solved

personally i hope so becuase i have DBZ tenkaichi2, and i want full everything! grr
