Birth By Sleep Custom Firmware With Custom Firmware On The PSP, What Size Memory Stick Should I Get?

With custom firmware on the PSP, what size Memory Stick should i get? - birth by sleep custom firmware

I hack my PSP to play ISO's buy, without the actual UMD's.

And these are the games you want to receive:

1. Final Fantasy VII: Crisis Core
2. Final Fantasy: Dissidia (leave)
3. Kingdom Hearts: Birth by Sleep (at departure)
4. Star Wars Battlefront 2
5. God of War
6. Ratchet & Clank: Size Matters
7. Daxter (maybe still think)


and perhaps some others.

Now my question: How big memory stick should I be?
