ok, i did it last night, heres what i did and happened.
I opened up the agetec, bought a 3rd party ps1 controller, some eletrical tape, wire, solder, and a swich. I took out the pcb of the ps1.
I soldered wires to all the buttons on the pcb, (up down left right, lp, mp, ,hp, lk mk hk, l1 r1 and ground). i then cut all the colored wires in the agetec. i soldered all the wires that i already soldered on the pcb onto the cut wires to there apropriate spots (ie. triangle to HP switch). i put a switch (one that turns off in the middle, then on if u flip left or right) and connected the agtec ground to 1 side and the ps1 pcb ground to the other.
I closed it all up. now heres what happened.
i put it to my DC and played mvc2 just fine when it the switch was on DC. everything worked. BUT when i turned on my ps2 and flipped it to ps2, it started just scrolling down the menu at super speed. when i push buttons they dont register but when i push up or down it registers up or down AND presses buttons. It seemed like everything was being pushed at the same time.
Anyone have any ideas of what i did wrong? I think it was the electrical tape touching other parts of other electrical tape on the 4 up down left right soldered parts. But im not sure if electrical tape carries a current to every other tape it is touching. The only reason i used tape is because sometimes the wires were coming off the solder so i taped over it and some touched each other.
i didnt plug in ps2 and DC at the same time so dont ask about that.
