hi,

my mate asked me if i could chip his PS-one so i agreed.
I already had a spare chip from previous purchase's but these where brought for the purpose of chipping older psx consoles.

So i contacted the supplier and they said that the chip would work but the PS-one wouldn't play import discs only PAL, if i wanted it to play copies and imports theni would have to purchase the chip for the PS-one.

hope this helped a little bit
