What made Xbox emulation so hard to do?

[AskaLangly]

Can someone answer that for me? Was it keys/encryption, or something else? I would understand 360 and One, due to online connectivity, and PS3/4... but still, why no original Xbox?

Hardware. The Xbox is more powerful than the PS2.

Also there isn't much need for it. Many games are cross platform and there's also the option to use a modded 360.

Or modded Xbox, since they're so easy to mod and get a big-ass HDD into.

Not really the reason it was a problem, but it wasn't helpful either, no point in going into it though as that will not change the fact there is currenty no progress in xbox emulation.

The best way to play Xbox games is still on an Xbox [I do use a PS2 pad though], 360 emulation of the Xbox (this is part software part hardware) is not 100% not even the hacked versions, plus you loose 720p and 1080i when playing Xbox games on a 360, though to play in 720p or 1080i you do require hard to find quality component cables for the xbox so not that many xbox owners will play in HD anyway

Xbox ports, well most of the multi console games the xbox seemed to get the best versions in one way or another for example some games that lagged on PS2 did not on the xbox there are games with other tweaks but mostly minor things

Someone did make an Xbox emulator called Xeon that runs the US version of Halo. Someone made that years ago, and I don't think any progress has been made since then.

It wasn't even worth a mention and not the only xbox emulator either but neither are in a playable state, Halo was released for PC as well anyway and obviously runs smoother

This is my understanding of why xbox emulation is so very hard to do, based on reading done while looking into the Xeon emulator years ago.

DirectX on a PC is software, so it is easy to patch and modify after installation. DirectX on the XBOX is hardware, so any patches need to be done on a per-game-basis and loaded into RAM.

XBOX is a very specific set of hardware, and games for the XBOX are designed to make the most of that hardware. This means that the system and games rely on that very specific hardware. Trying to add a larger HDD, for instance, takes a lot of programming knowledge that can be installed as a Mod, which seems to be specific to the HDD you are installing. On the other hand, trying to make games that rely on a specific brand and MB size of RAM run with other brand/size RAM is difficult. So trying to make an emulator that will also play on any brand/size of RAM is EXTREMELY DIFFICULT!!! Then you would also have to make that emulator run those Hardware-dependent games run with various CPUs, Graphics cards, sound devices, Cache, etc. all while still needing to enforce a custom built version of DirectX suited to running XBOX games.

It seems like the best bet for actually making all this work should be Virtual Machine, most likely as a secondary boot configuration. But nobody has been able to make this work well enough to be easily implemented on a wide variety of machines, so no emulator.

Also that no team could stick together or anyone else really stuck with it afaik

Emulation is obviously possible but reverse engineering must be a pain in the ass, Microsoft was forced to emulate the original XBOX on the XBOX360 they did know what they were doing, many games are playable some aren't and some are glitchy slow and with some running too fast at some points, I guess they didn't really bother to increase the compatibility, yet that's better than nothing.
So my guess is that the next generation of emulators (xbox 360 emulator) could probably be used to emulate the original XBOX.

It was weird to play the house of the dead III on my XBOX 360, the game ran a bit slow and the house of the dead was fine but at some points gameplay was just too fast... huh.

Yeah, I think all the technicalities aside part of the problem could potentially be a lack of interest. The best and most well-known games for the system (Halo, Fable, etc) were also ported to PC, and otherwise it basically seemed to have titles that were cross-platform with the aforementioned PC but also PS2 and GC- this is of course aside from a few oddities. Correct me if I'm wrong, I owned an Xbox myself at the time but never really played it very often.

It's a shame- there are some obscurer titles on the system that never made it anywhere else. I'd love to play games like Mad Dash Racing and Panzer Dragoon Orta on my PC, but alas maybe it's not meant to be.
