When you import a console you have to use a step down converter, pretty common in the import market. You’ll need one of 100watts or higher as the ps2 uses 100, and having more than the required is always a safe bet, in fact id highly recommend it.
Course you could always modchip your ps2 although due to kiwi laws im not failure with, im obliged to say; that could be illegal etc
Yeah it sucks about no pal edition i guess we just missed the mark and ended up with it on xbox, i actually have it imported on ps2, you know a ntsc ps2 is worth its weight i found, GG accent core is only available in ntsc format too (as far as i know), unless you want it on the Wii in PAL…
So yeah never hurts to pick one up at the right price
edit oh yeah you could always find a friend on GGPO/2DF to be a spa partner or something, let them random block or attack to practice parry etc, worth a try m8
