Does this mean they will ship it with a Virtual PC style enviroment on it - since you can not run x86 code on a PPC Chip - let alone a 3-core PPC chip configuration
We all know that VirtualPC can run on OSX on a G4/5 I guess with the 3GHz clocks we have on the 360 will be powerful enough to emulate a 750Mhz cut down P3....
Discuss. :)
Maybe they've sneakily hidden a Celeron-M in there;).
If it does have some sort of x86 emulation environment on it, then I'm sure people will find ways of exploiting it to run random x86 software on it :)
The core hardware seems more than powerful enough to emulate a 733Mhz P3/celeron and a Geforce 3 with no problems.
the core hardware could _NEVER_ emulate it.
they've said *some* games will be backward compatible.
there will be replacement xbox360 binaries on xbox live, which require the original xbox data discs
Chance to exploit the Xbox 360 as powerful servers?
Imagine a whole rack of Xbox 360s process data faster than a rack of high density dual opteron blades, at a fraction of the cost?
I'm saying that they should write a software emulator that runs on XBox 360 and emulates the original Xbox. I know thye probably won't do this, but there is no reason they can't.Quote:

the reason they can't is that the xbox 360 isn't even close to powerful enough to emulate the original xboxQuote:

What you say makes sense.. but how did you know? :)
Supporting psp games would not get them sued?Quote:

Any reson it could not play music from an ipod? does ipod not use mp3/ogg/flac? (well not the last two.. but mp3?).. If so why would you want to? I suppose the chavs will...
My neighbor's Athlon XP 1800+ with a ti4200 is fast enough to emulate an xbox.Quote:

Even though an x86 processor like the athlon XP can run alot of the xbox 1 code natively and the cpu in the XBox 360 cannot, I have a hard time beliving that the XBox 360 CPU is too slow for a well written dynamic recompiler to match the final performance of a 733MHz P3. Unless, not having branch predictors (if the PPC core is similar to the one in the cell processor) totally kills dynamic recompliation. I'm not a programmer so I wouldn't know for sure.
dynamic recompilers are simply not an efficient or reliable solution.Quote:

microsoft cannot & will not claim partial backwards compatability and then have messy half-working games out - it'd kill their image. games support will be per-game, and in cases of per-game support, anything other than replacement binaries is dumb
also bear in mind no games console ever released has been able to emulate its predecessor - the game boy advance can't do it, the playstation 2 can't do it
also, bear in mind that the graphics is likely to be a bigger blocker than the cpu - from endianness issues up to slight differences in the way nvidia and ati kit renders things. given that xbox games are all written for a pretty cross-platform api, it'd be far easier to recompile (and fix the few games that need byte order and word length fixed) than to try & work on compiled code.
