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.

  1. PS2 and PS1 games? by jamesjw · · Score: 4, Insightful

    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.

      There sure is: the revo will be backwards compatible for gamecube (and earlier Nintendo) consoles, and the PS3 is apparently backwards compatible (if not 100%, then close to it). If the Xbox360 is only partially BC and the other two are (for the most part), then they could be shooting themselves in the foot with regard to competition in the next gen. If somebody needs to keep their Xbox to play Xbox games because it won't play *all* their Xbox games, what's to stop this theoretical person from getting a PS3 or Revo instead?

      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.

      Actually, PS1 has 1MB of Video RAM (also models starting from around 98 have 4MB main RAM...but that's moot point anyway since it was used at most as data buffer, often not at all).
      But of course your argumentation is correct.

    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).

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.

      I've got a 360 on pre-order, which I'll be picking up the day it comes out. I've been a vocal defender of the X-Box and the 360 for some time. Even I have to admit that this list is not good enough. The impact of this on my own games is:

      Working

      BG: Dark Alliance 2, Battle Engine Aquilla, Crimson Skies, Forza, GTA3, GTA:VC, Halo, Halo 2, Jade Empire, KOTOR, KOTOR 2, Spyhunter 2.

      Not working (*s indicate games whose inclusion here frankly defies belief, as they've been major titles)

      Area 51, *Burnout 3*, *Burnout Revenge*, *Chronicles of Riddick*, Colin McRae 04, *Full Spectrum Warrior*, Mechassault, *Mechassault 2*, Panzer Dragoon Orta, Secret Weapons over Normandy, *SW: Republic Commando*, Wallace & Grommit.

      The titles I've starred there are some of the biggest games on the X-Box. A good number of them are relatively recent releases. As far as I'm concerned, there's no excuse whatsoever for them not being included. All I can say is that this will need to change by the launch date.

      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?

    The could offer some sort of trade-in program where you could get the new version of the game on the cheap if you turned in your old disk. Of course most of these games are non-Microsoft products, so such a program would need to be offered by lots of different companies. In the long run this would probably have been cheaper than trying to implement backwards compatibility. Many times the best solution to a technical problem isn't technical.

  8. Their first big mistake by techstar25 · · Score: 3, Insightful

    Here it is. Microsofts first huge mistake. If they were only selling one version of the 360 at launch it wouldn't be a problem, but since the "CORE" package will not be backwards compatible with anything, we're are going to have a lot of unhappy people on Christmast morning when their old Xbox games don't work. This is a disaster in the making.
    Now they have to market it as two different versions of the 360, the backwards compatible version and the not backwards compatible version. Considering the CORE system was to be marketed towards casual gamers, it is these same casual gamers who don't want to spend $60 a pop on brand new games on launch day.
    Are they trying to make the CORE system obsolete before launch? They can't be a wise idea, especialy since price is king at Chrismas time.

    From the interview:

    Xbox.com: What criteria do you use in choosing which Xbox games will be backward compatible on Xbox 360? How far back into the Xbox game library are you going to go?

    Todd: When we say Xbox library, we mean the entire Xbox library. This ranges all the way from our launch in 2001 up to games that haven't even shipped yet.

    If they can do 241 games in a few months, including writing the emulator, I don't imagine the rest will take that long. In the meantime, you'll just have to be content with running your Xbox games on your Xbox, tough as that is.

    In the interview, he mentions that people who don't have the Live service will be able to download the new binaries to their computers, burn a cd, put that in their 360 and it'll update. I predict that this is the exact mechanism that will initially be exploited to allow arbitrary code to run on these things. Just a hunch...
