Xbox 360 Backward Compatibility Finalized

News for nerds writes "Microsoft has finally announced the list of the 213 Xbox 1 games playable on Xbox 360 at launch. A software emulator is required for each original Xbox game, which means you need an HDD for these games to work on Xbox 360. While it is expected that the list will grow in future via Live update, as of now it lacks first-party titles such as Project Gotham Racing, and other popular titles such as DOAU/X, Doom 3, Far Cry, KUF, Panzer Dragoon Orta, the Splinter Cell series, and the SW: Battlefront series." Xbox.com is also featuring an interview with Todd Homdahl about the quest for compatibility.

PS2 and PS1 games?

[jamesjw]

Why not just build something with built in hardware emulation? like the PS2 does with PS1 games - i know its not 100% but it makes sense to do it this way doesnt it?

Didn't Sony include the essential bits of the PS1 system in the PS2 in order to allow backwards compatibility? I don't think NVIDIA would let Microsoft do this, as they own the rights to the graphics card used in the Xbox.

It's makes perfect sense, but from a technological aspect it's impossible. The Xbox 360 uses a treo of PowerPC processors to run games, in sharp contrast to an intel pentium III of the original xbox. A lot of code simply will not go over. Given these constraints, Microsoft could have either said "fuck it, no backwards compatibility" or they could try their best to port some games anyway. I'm glad they chose the latter.

Correct. The IOP (IO processor) on the PS2 normally handles input from the DVD, game controllers, USB, etc. However it's basically a souped up version of the PSX CPU with all the associated bits, so send it the right instructions and it detaches from the EE (main processors) and the system becomes a nearly 100% compatible PSX.

Sony could do this because the PSX CPU was 33MHz and had 2MB SDRAM and mere kilobytes of graphics memory. When the PS2 was being made the cost of each IOP must have been measured in tens of cents. The Xbox 360 is being released too soon after the Xbox; the 733MHz Celeron plus the NV25 GPU is still fairly expensive.

Since when did not having backwards compatability become, "shooting yourself in the foot"?

Since your two biggest competitors (Sony PS3, Nintendo revolution) have announced that feature? And that it was one of the major reasons the Dreamcast was hurled into obscurity and securing the Playstation's spot as market leader?

Outside of Nintendo's handheld devices, the extra hardware to let the Sega Genesis play Master System cartridges, and the PS2's ability to play certain PS1 games there really aren't many examples of backward compatibility in consoles.

If by "certain" you mean all except 10 out of 8000, even the controllers were largly compatible. The new slimline model is getting complaints because it is incompatible with 7 PS2 and 40 PS1 games. That's 0,5% of the PS1 games, up from 0,13%. The two market leaders, Nintendo (handheld) and Sony (console) are doing it, those that haven't have failed. Can you say "formula for success"? If that was supposed to be an argument against me, it's a pretty pathetic one.

Software Emulation

[Station]

Looks like the entire thing will be (as expected) run off of software emulation. Really, considering the technical challenges involved (I know, software emulation isn't impossible, but the fact that it can run the system at full speed on a completly different hardware type is nice) I'm pleasently surprised at the number of games already available. I also like the fact that the system will run all your old games in HiDef and add a layer of FSAA (almost like the old Sega 32x).

My collection

[ninjakoala]

Just to give you an idea of how bad it looks at the moment, here is my collection divided into working and not working:

Working:
Amped, Colin McRae '04, Dead or Alive 3, Fable, Forza Motorsport, Fusion Frenzy, Halo, Halo 2, Jade Empire, Phantom Crash, Sega GT 2002, Knights of the Old Republic, Knights of the Old Republic 2, The Thing

Not working:
The Bard's Tale, Blood Wake, Burnout, Dead or Alive Ultimate, Dragon's Lair 3D: Return to the Lair, Morrowind, F1 Career Challenge, Project Zero, Gunvalkyrie, Knockout Kings 2002, Links 2004, Mechassault, Outlaw Golf, OutRun 2, Panzer Dragoon Orta, Phantasy Star Online I+II, Project Gotham Racing 2, Rainbow Six 3, Rallisport Challenge 2. Jet Set Radio, Serious Sam, Shenmue 2, Splinter Cell, Taito Legends, Unreal Championship, Wreckless, Yager

And here I was thinking "oh, ok, a couple of my games won't work... worst case scenario half won't work". This is just crazy though. I hope they boost the compatibility in a big way, or I just can't see my self upgrading, since that would mean I would have to keep the current black box under the tv as well.

Re:My collection

[GizmoToy]

It occurrs to me that some of those titles may not be scheduled for backwards compatibility because they are to be release native for the 360. Burnout Revenge comes to mind, and I'm sure a Splinter Cell will make it. Perhaps Microsoft is trying to force everyone to buy the latest version (native to the 360, of course) of many of the popular series titles?

Re:My collection

[JPyun]

Wow. You have a lot of shitty games.

Wow, Microsoft IS all-seeing!

[tgd]

Its like someone looked at my rack of XBox games and picked everyone one I've finished to be compatible, and every one I haven't to not be.

*tinfoil hat*

Emulation +

[GweeDo]

Don't forget that all your emulated Xbox games can now be ran at 720p or 1080i with full Anti-Aliasing as well. This could help a number of games look really nice. Here are some shots of Halo and Halo 2 in 720p from Bungie. It does make a very nice difference.
