"Too Early To Say" How Many OG Xbox One Backwards Compatibility Games There Will Be

@superklyph: That is due to the custom nVidia video card used. And there is a good emulator, it is called the Xbox 360 (LOL!).

But technically it should be much easier to get an original Xbox emulator running on the One than it was on the 360 (and easier than the 360 emulator on the One), especially for Microsoft who are familiar with the original design inside and out. But the OP is wrong about one thing, this will use a similar solution like what was done for 360 BC on the One in that it WILL also include the emulator and OS with each and every title. That is a little unfortunate since then it will limit title availability due to licensing issues (which would not exist if running from the original media), but the advantage is each game will have the emulator specifically tuned to each game for better performance.

@TightNinja: Um, every full fledged emulator that has ever existed outperformed both the original hardware as well as the emulators provided by the original creators. Makes sense because the original creators use their emulators to give you an experience as close to the original game as possible and are also limited by licensing issues with third parties.

So, an entire library will NEVER be available for emulation by any company thus will ALWAYS have less options than a fully supported fan emulator which disregards legal issues of all kinds. Fan emulators also allow you options the games never originally had such as higher resolution/new resolution support, mods and even online play for games that never had them originally (I personally play Soul Calibur 2 and Super Smash Bros Melee online on Dolphin emulator which are options these versions of the games don't have anywhere else).

Seeing that, Xbox being emulated on 360 means nothing since you're restricted by what MS emulated which wasn't very many titles anyway and many of them were poorly emulated or had game breaking issues as well showing that even MS sucked at making a quality emulator for their own hardware. Plus MS never cared to fix any of the games with issues in their emulator. If fans cared enough to make a proper Xbox emulator, you could get access to the entire library on top of gaining the typical options that come with emulator, fix game breaking issues and far outperform the MS Xbox emulator in options alone.

@TightNinja: it's hilarious to play too, who needs to score when you can K.O the whole opposition!!
