I'd like to mod my PS2 slimline to play Japanese PS1 games (and maybe a couple of Japanese PS2 games as well). I don't think I want to use Swap Magic because it seems like a hassle in comparison to just modding it with a chip. Is there a certain chip that's best to get?

For instance, this site offers solderless ones,

and this one looks good: http://www.mod-chip.com/ps2/ps2-modchips/modbo-4-0.html
It seems to have more features.

There's also this one: http://www.mod-chip.com/ps2/ps2-modc...nity-1-99.html

I don't know which is best. Any help is appreciated. Thanks.
