I recently have been using a freemcboot memory card to play games on my ps2 off usb, however it kinda sucks for bigger games due to fragmentation and my usb doesn't have a lot of storage either. I recently got a cd/dvd burner and was hoping I could just burn the .iso's onto the DVDs and run it using a program from freemcboot but it looks like the only way is with an esr converter? I can't find an esr converter anywhere, would love to have some clarification/help with this
