Yes, the ICs i used are the same, but not the connection...that makes the difference.
I cannot negate that i based my schematic using kashi's one, but i tryed his schematic and didn't work...
The PCB is in the link i posted before.
I did my project on a protoboard and works perfect.
I've done a PSX to SS converter too, with fully digital/analog functions(so, PSX analog pad works just like Sega 3D analog pad)but, i had problems with original PSX joysticks, they had a lot of lag(aprox. 1 second) but with two non original PSX joysticks, the result was almost perfect(almost because there was some ghosting on L1 trigger and the triangule).
Sadly, i get bored of trying before finishing the project( i made it 1 year ago) so...it's incomplete. Maybe i'll finished it and post the necesary info.
Regards.
