playing games on a fat32 external drive?

Hello. I have a 500G external hard drive that is formatted to fat32 for use with my PS3. I have all of my ps3 games backed up via usb ex hd along with emulators, etc.. Anywas, i wanna backup my ps2 games to my external hard drive so i can play them on my ps2 slim softmodded ps2. Problem is... fat32 only fits files under 4G. when you back up a ps3 using the ps3 is splits the files and then brings them back together when you are ready to play them via you ps3 loader(mulitman, etc.. ) is this possible for the PS2? Is there a program that can split the ps2 iso game file so that it will fit on my ex fat32 hd so the ps2 will play a backup from a fat32 ex. hd? thanks.

This will help with PS2 games

that will help but you will find that there are quite a lot of games that are less than 4Gig in size . of the 179 games i have 51 are bigger than 4 Gig approx 1/3

Btw.: A lot games fit directly as ISOs onto external HDD.

A lot PS2-Games are less than 4GB. ;)
