Those gamers using an 80 Gigabyte PlayStation 3 to play Kingdom Hearts Re: Chain of Memories (PlayStation 2) may have noticed little attacking options available during the first boss fight. This is all due to a minor glitch in the backwards compatibility. A fix for this however hasn’t been announced.

But do not worry! – There is a work-around for those with little patience to wait for the fix.

1. Download a Save Game File from after the tutorial (first battle).
2. Place the Save Game File in a folder called PSV.
3. Place the PSV folder in the folder called Export.
4. Place the Export folder in folder called PS3.
5. Get your hands on a USB Drive/Memory Card and insert into PS3.
6. Transfer the save game file to PS3 using Memory Card Utility (PS/PS2) in the XMB.
