I have a hrap 3SA which is made for ps3. Are there any converters so i can plug them into ps2 ports that some arcades have or do i have to switch the pcb out?
No, there is no such converter. You don’t have to completely switch the PCB out, though: it’s really easy to dual-mod the HRAP3 with a PS1/PS2 PCB. Use the forum search.
USB is end of the line in Converters.
Don’t we have a converter thread!? This is the second unnecessary new thread on converters!!
