Have you heard of the SEARCH key on the internet?
NEO2.2 is an 8 wire mod that allows backups to be played with a single swap after booting with Action Replay 2/Gameshark 2 or DVD Region X. Protected EA Games and all DVD-Rs require a special boot method; in the case of DVD-R, an original game with a higher Table of Contents than the backup game must be used for the first swap an the DVD-R itself for the second swap. A real pain. Import originals cannot be booted with NEO2.2 and it puts ut 5v onto a 3.3v board eventually causing damage.
Origa (
www.origachip.com) is a 15 wire mode that uses a single swap with the aforementioned utilities and also boots imprt originals. Nothing else to say about it other than it is no contest between Origa and NEO2.2.
NEO2.2 is past its sell-by date.
