I took out my DMS3 modchip out of my now broken fat PS2.
But i guess it's now irrelevant because you can pretty do everything that modchip is able to do, but with FreeMcBoot + OPL + MX4SIO.
Back in mid-2000's, i got that installed in my fat PS2 to be able to play with Japanese games.
The only thing i can think of, that FreeMcBoot and OPL can't do, is booting Japanese discs on a US console. But at this point i would just install the ISO on the MicroSD for the MX4SIO.
