No. That is for the PS2 Classics.
Of course you can make a memory card for PS1 games, since they're all compatible with PS3. Please research more about PS2 compatibility because I am trying to tell you that newer PlayStation 3 game consoles cannot play physical discs of PlayStation 2 video games. They cannot. I don't know what to tell you, but they just can't... Not for the time being anyway. The only way you can play PS2 games on newer models is by purchasing the current PS2 Classics for $10 apiece.
I don't know if you're just trolling or you're adamant in your false statement, but please refer to this before continuing to perpetuate a ridiculous argument over the internet.
You cannot. It is physically impossible. I just tried, with 11 different PS2 games I owned, and the discs are read as "Unsupported Data". It is an unsupported format in newer PS3s and even Sony can debunk your "instructions".
Ok, look, i have a ps3 slim.....follow? understand?
Ok, I have the "DISC" of Castlevania "Curse of Darkness" in my "PLAYSTATION 3 slim" and im at the start screen. and now i can PLAY it.
Follow my proceedures that are above a few paragraphs.
If you can, you should post a video of you starting, and playing the Castlevania game on Youtube, so you can help prove what you are saying...
