xqemu VS xemu

These projects are called compatibility layers, or "translation layers" sometimes. I think XQEmu (OG XBox on PC) works the same.

Yes:

Are both original Xbox emulators built off of QEMU. I've only used Xemu, but performance was pretty good for the games I tried on it (it doesn't have a way to upscale rendering yet though).

It's indeed a bit like a kexec.

On system initialization, kernel routines are copied into RAM by the bootloader[1]. Executables run in ring 0, and have a jump table to call kernel routines in their own address space (IIRC) [2].

As such, loading any executable counts as a soft reboot.

Also, there is a functioning open source emulator, Xqemu [3] (and its sibling/fork focused on speed and compatibility more than accuracy, xemu [4])

I recommend reading "17 mistakes Microsoft made in the Xbox security system", which is very informative [5].

There is one emulator currently that does do that, the "XQEMU" emulator for the original Xbox https://xqemu.com/

It's in its infant stages at the moment according to the "Emulation General" wiki and focuses heavily on "accuracy" over performance

Other emulators such as CXBX-Reloaded have made larger strides, currently emulating roughly 10% of the software library

It's also worth stating, while the Xbox seems like an "easy" target, being based on an ia-32 (Pentium III) PC with an Nvidia GeForce chip (somewhere between a Geforce 2 and 3 at the time) it is an absolutely monstrous beast with minimal documentation about its hardware and numerous "gotchas"

It also has a very small library of 'exclusive' content which detracts from gaining many developers

Xbox: Xemu is the best Xbox Emulator according to the emulation wiki: Download Xemu

Black Stone: Magic & Steel / 4 players / Xbox: Plays great on Xemu.

xemu is another option, if you have a Windows rig with sufficient power. Beats me as to how well Coast2Coast runs exactly, but the site boasts it to be playable at least.

I think they is an option to fix this within the emulator. Check out the GitHub page, it does have some details.

Xemu is the best current XB emulator, it comes complete with Insignia (Xbox Live 1.0 reimplementation) support, with a little tinkering.
