Mod chip vs. flip top

[woo124]

Hi,

I'm trying to decide between mod chip and flip top for my Japanese 15000 PS2. Do you guys have any ideas of which option I should take? The issues with mod chip are higher price and loss of functionality. I heard from modchipworld that I could lose functionality by having mod chip installed. If there is a Japanese game that will not work with a mod chip, by having a mod chip installed, I won't be able to play it whereas if I didn't have a mod chip, it would play fine because my console is Japanese PS2. Also, I read from some of the threads here about problems with mod chips. I don't know exactly what kinds of problems they are, so if someone could kindly point out a few major problems of Matrix Infinity mod chip, I'd really appreciate it.

Thanks
