- **Encrypted executable image** - Yup, for various reasons the executables on Xbox360 are encrypted. There are some cleaver guys in Russia though that figured how :)

- **Different and outdated GPU architecture** - If we want to see any graphics rendered the GPU needs to be emulated. Ther are two hard nuts to crack: first, the shaders we see will be complied into the GPU compatible format, no HLSL on input, sorry. Those shaders will have to be reverse engineered as well. Secondly, the Xbox360 GPU was using ~10MB of internal memory called EDRAM that was serving as a temporary storage of render target for the duration of rendering. Although some card today still use similar concept this is never exposed directly to the user. Since there a lot of differnt ways people used the EDRAM on Xbox this part has to be emulated. To be honest probably differently for every game.

- **Inlining of graphics/kernel functions** - Some of the functions used while compiling the executable were inlined directly into the compiled code making it much harder to write a simple API level wrapper. This kills the dream of making "function level" wrapper where we could just go and wrap the "d3d->DrawPrimitive" call directly. Nope, this is not going ot happen.
