OG Xbox BC on X1 is clearly built on the emulation work done for 360.

[Mr Puggsly]

So here's a few things I noticed about OG Xbox games on X1...

1. All the games added were already compatible with 360.

2. All the OG XBox games added X1 BC were already on 360's marketplace or were added to the 360's marketplace. Such as KOTOR, it always worked on 360 but now you can buy it digitally on 360.

3. The emulator on 360 is notoriously buggy and has performance issues. But its very likely MS is starting with the old emulator and just updating it. While performance and resolution upgrades are primarily from brute force power.

So what does this all mean?! Me thinks the games going to be added to this service are the titles that 360 could already play.

BC on the 360 had many games on its compatible list so much of the work is already done, https://en.wikipedia.org/wiki/List_of_Xbox_games_compatible_with_Xbox_360

In a nutshell, X1 is basically using the medicore OG Xbox emulator from 360. But via brute force power of X1 and emulation tweaks the emulator is getting better. Any OG Xbox game added to X1 will also be compatible and sold on 360, based on what we've seen so far.
