Fredscape:
You need all Jap stuff (board and cart), or a universe bios chip if I`m not mistaking (still need to test one of those
)
that`s about it I guess
This is not true, what really matters is the bios in your board, a JPN cart will play in English in a board with an English bios. However, in some games you can choose the language anyway, and some others will only pay in JPN (the JPN-only games text-based, like the quiz and mahjongs).
I suggest to install an unibios that will give you total control; <a href="http://bios.cps2shock.com" target="_blank">unibios</a>
