I already have the saves on my PC. I have a memory card adapter on my launch PS3. I just want to know if the files will work on an emulator.
In that case, it seems like it is possible according to the PCSX2 wiki. I'm unsure whether you'll need the progam "myMC" or not, according to the description it is vague about that.
The PCSX2 emulator stores memory card information in the memcards subfolder of your PCSX2 configuration folder. Following the PS2's 2-card format the emulator names both memcards Mcd001.ps2 and Mcd002.ps2, which use the emulator's native .ps2 file format. Similarly these files are also around 8 MB in size just like the physical Sony PS2 memory cards.
Currently most PS2 memcard functions are emulated and considered usable.
