is it better for the ps2 to be placed vertically or horizontally (disc wise)?
and i should NOT put my GC on top of the ps2 (im limited space wise) even though its not on the cd part right?

•and i since i have the first version PS2 (its japanese), should i be worried about it playing different kinds of cheap(er) media?
•finally, my Ps2's already scratched up tekken tag (fixed partially thanks to CFizz), though i do believe by moving it when its on/playing, will this hurt my ps2, as it does sometimes make kinda clicking noises/freezing up when loading certain characters/games?
•and will my lazer play DVD9 games (i dont' have xenosaga), as its V0/V1?

•my ps2:
V0/V1 (SCPH-10000) Japanese Version
2 8mb mem cards (one with DVD all region code)
no mod (looking for M2J, when available, anyone?)

-thanks
