1st: Gackt is a lamor
2nd: The xbox's cpu is not pentium architecture, and if you didnt know that you should stfu
3rd: The emotion cpu would be lucky to be as half as powerful as most people think
4th: Ps2 could easily be emulated on the xbox, but obviously it is not going to be very fast because two different precessor instructrions.
5th: The emotion engine must handle all T&L Arguments, hence no gpu, and most of the time games for the ps2 will hardly use the shitty spu on the ps2. The xbox obviously has an extremely powerful gpu/spu, which takes most of the load off of the cpu, so a more powerful cpu is not needed.
If you want technical reasons for why the emotion engine is the biggest piece of shit, just read the stats on it, twin vu's linked by 150mhz dual pipes, which obviously isnt very effective, etc, etc. do research before you go saying shit
