Xenia Is A Working Xbox 360 Emulator,Showcased Running Commercial Game For First Time

Back in March, we informed you about RPCS3 running a commercial PS3 game. Well, here is some good news for X360 fans as Ben Vanik has released a video for Xenia (a working Xbox 360 emulator), showcasing his emulator running a commercial game for the first time.

According to Ben Vanik, Xenia is using his debug interpreter, something that explains why it is extremely slow for now. And the first game that was showcased running on Xenia was Frogger 2. Yes yes, it is not much for most of you but this is a big success and a huge step in emulating X360.

Looks further along than the PS3 emulator.

For those asking for OG Xbox emulation:

I'm starting to have a hard time believing this post. OG Xbox harder than 360 and PS3? Seems more like lack of interest to me.
Apparently the Xbox was poorly documented or something, which makes emulating it way harder. It also has some funky software stuff going on IIRC.

So exciting. So great.

I could see it. Less documentation, some slightly custom parts, yet still far more complicated than anything prior.

Not "Wii fast"(that was a very special case), but that is a damn fast to have a working emulator for a console that is still "alive" ! =O

Didn't knew about the ps3 one.



Can't wait for the "play X game in REAL 1080p" comments =P

Saturn still don't have a GOOD emulator ... some hardwares are just not much emulation compatible =/
 
how much of a rig you need to emulate a 360?

The 360 had an in-order, Triple Core CPU (Xenon) clocked at 3.2 GHz, each core capable of SMT (so 6 threads) and a Radeon equivalent (Xenos) somewhere between the X1800/1900 and the unified shader 2900 XT.

Assuming acceptable speed and 1:1 thread allocation, one would need (at a minimum, for this stage) a stupidly fast quad core with HyperThreading (a typical Sandy/Ivy Bridge/Haswell i7) combined with something like a card which is at least 20x faster (to account for emulation and processing overhead) than the Xenos GPU and with loads of VRAM (680/780/Titan).

Dual core CPUs and mobile devices/phones need not apply at this stage. Or ever.

After optimizations have been done, the requirements may drop down in the future.

Definitely subscribed to this thread.

Says who?

The laws of computing.

Theoretically it's possible to increase a game's performance via emulation, but only if 1) you emulate the system at a higher clock rate (which can lead to glitches), and 2) if the game's framerate isn't artificially limited to 30 in the first place, which is usually the case for 30 fps games.

Question, why hasn't the original xbox been emulated?

Also this is good, I love Gears 3, Halo 3, Bayonetta and countless other exclusives. If anytime in the future we get to the point where we can make them look better like dolphin or PCSX2 can then by god...

Although being HD systems I'm not sure if you can make a sub720p game into a 1080p through emulation. I really don't know much except I might need 20 cpus to run the damn thing (40 for PS3).
 
Quoted to make fun of you in the present, because you obviously don't understand computing if you think an emulator will magically make your 30 fps games run at 60 fps.

Of course it doesn't happen automatically, but they can certainly make it happen.

I hate to break it to you, but when 2037 rolls around and you're finally able to emulate PGR4, it's still going to be running at 30 fps. I'll gladly eat my words if they manage to develop a process which adds frames of animation that don't actually exist.

No, they can't. Games that were made with a 30 or a 60 fps framelimit in mind will run at that. Same goes for PC games FYI, while guys like Durante can change things like resolution a game that's programmed to run at 30fps will max out at just that.

I'm aware that capped games will always be limited (unless of course some hacky and/or buggy mod comes out to somehow patch it), but not every game is limted. The first one that comes to mind is Red Faction: Guerrilla for Xbox. That seems to fluctuate from (I'm guessing) 20fps to around 60fps depending on what's happening.

If the game isn't capped and purely depends on the speed at which the console can handle it, then surely emulating a "faster version" of the console with upped clockrates or whathaveyou should in theory increase the performance?

This is a very bad example, yes I get what you are trying to say. BUT, not only did Durante improve the resolution, ambient occlusion, etc., he ALSO unlocked the frame rate from 30 to 60 fps. I agree with what your saying, but it's not impossible and that was a bad example.
 
There are several precedents for framerate increases via emulation. Two off the top of my head include

Kindgom Hearts 2 at 60fps
This game uses emulated PS2 cheat device hacks to unlock the framerate. This one works really well.


Super Smash Bros brawl/Project M at 120fps
The trick is to force dolphin to run at120fps, and then play at half speed using in game options. This one sucks.
  • Playing this way substantially changes the how the game feels and plays
  • The difference in feel between Training mode 50% and Special Versus Slow. Each has a different hard coded speed setting, so they play/feel noticeably different from one another. Training mode is more accurate (obviously), but game options are obviously limited

It should be noted however that unlocking the framerate causes glitches and messes with the game's physics.

While yes this is true, and I am not disagreeing with you. He just made it sound impossible. There are graphical glitches and errors with almost all emulated games.

Games built around 30 will likely stay around 30 without a decent amount of hacking around.

I think there's some miscommunication in this thread.

The Xbox 360 will be emulated "at 60fps" in the sense that some day computers will emulate the 360 fast enough to generate every one of the 60hz that it outputs, even if the games run at 30 or whatever (2 updates per frame).

The Xbox 360 will not be emulated "at 60fps" in the sense that the games themselves will make a new image every frame, at least across the board, because that's not how software works. There's a reason Metal Slug is still 30fps even though the Neo Geo has been emulated inside and out, and this will be the same case with many 360 games.

Most Western engines support varying framerates, especially since 2005, so it's believable to me that, with the huge amount of middleware-based games and Western-developed games in general on the 360, we could see more games with simple hacks than in prior generations. But I'm still not super confident.
