Well the difference between PS2 running SOTN and XBOX360 running SOTN. PS2 shows it in 480i and there's dithering going on (hence, it's PS1 game) so it looks fine. On XBOX360, it actually is upscaled to 720p so it look pixelized. Dithering is gone as well. I prefer playing without enhanced, just because I feel it looks better and original.
Still, $10 isn't so bad and fast loading also I noticed it's missing cutscene (intro). Not a big loss, really. I wish they'd apply mipmap for 3D background or something hehe.
