Hello. As the title says, what's the best Slim PS2 modchip you can recommend, feature-wise, especially for booting both ps1 and ps2 games? And sorry if I'm making a question that may have been already asked, but I didn't get a clear answer from all these threads.
My console is a Slim PS2, NTSC USA. I don't know the serial number because I'm using a modcase.
