Of course it have. or I don't know, I can say yes because sometimes my Megaman X5 copy works, I don't know if the disc is it or the disc drive, again, I don't think my disc drive can be, I already said it, I restored it and changed the laser.
My cousin gave me that PSone, I just restored it.
It still doesn't work ;O;
maybe it's my disc?
EDIT: the weird thing is my PSone doesn't load the disc, but ePSXe loads the disc.
Then the disc is working but your PSOne doesn't reads it... as sarkwelvin asked, do you have a modchip?
