Important - None battery version
PSP Action replay works 100% with all firmware from 5.00 up to and including 6.20. Version 6.30 of PSP firmware is now available but currently Action Replay is not compatible with this version. In order to maintain full compatibility with Action Replay it is important that the user does not upgrade to this version until further notice.
