so, im in the market for some import ps2 games that ive wanted to play for a while. BUT i do not want to spend the money to get a console imported if i can avoid it, so my plan was to run the actual disc (not rom or iso, cause that is wrong

) on a ps2 emulator. does anyone here know if the ps2 emu is reliable?
my other queries are
1. will the emu run actual discs... i refuse to play roms
2. if yes, will it play japanese discs.
3. do the emus improve picture quality at all such as anti ailasing.
thanks in advance
