Thanks for posting it as news.
love reading about this

Even the progress is not as fast as everyone would like,
its good to know about it! Thanks!

Yes! Thanks for the update. This project is one of the best amiga projects in a while. Very much needed. Once the UAE JIT is finished it would be a real win if Hyperion integrated it into workbench so 68k stuff "just works" integrated with the OS.

Petunia?

pavlor

err.. you know what i mean.. UAE auto launching i'm speaking of.

I'm quite familiar with petunia.

RunInUAE

glUAE

There's kind of a big difference. Petunia doesn't emulate the custom chips, EUAE does.

@all

Well, what is ment is 68k + Chipset emulation

But, as the title said, bad news is that this project (even it is Petunia`s authors) will not add just chipset emulation to the OS, but improve E-UAE.

That is also a good approach, since everything beyond OCS is not well playable on SAM 440, and fast AGA games are a bit limited even on SAM 460. We don`t really need X1000 to emulate old Amigas We just need this project to get finished.

So, both RunInUAE / glUAE would benefit too since they clearly use E-UAE
and yes it would be good to see one of those solutions integrated within
AmigaOS 4.x, just like AROS did.

Also this version could be easily portable to MorphOS too, so all AmigaOS flavours - AmigaOS 4, MorphOS and AROS could finally be "Classic compatible", not just Amiga Forever (and thus will remove the main mind obstacle of "this is not Amiga" way of thinking and dismantlement with new OS`s)

You can not play all games with JIT enabled so it won't necessarily help it at all.

Almos : I perfectly understand you when you say "The source code is so deeply convoluted, riddled with residue from debugging, useless functions and scary/cryptic workarounds that I had to give it up."
I faced the same problem with the DosBox source code and that limited the possible changes and improvements. I had a look at the DosBox JIT part and it seemed very difficult to port to a new architecture (I mean PowerPC).
I wish you good luck for the project !

@realize

I see there is some confusion about what JIT does.

JIT speeds up CPU (68020/030/040) emulation in UAE that’s all it does,
JIT does not integrate UAE in the host operating system.

I order to Integrate UAE in to the Host OS, you need to patch the emulated OS, so that it talks whit an abstraction layer / wrapper whit in UAE that can act as an layer between the host and the emulated OS, the layer will keep track of all Open windows and Screens and open and redirect to the host, also it will need to keep track of events coming from the host OS, and translate this.

The parts of Emulated OS that needs patching I believe is graphic.library and Intuition.library.

@itix

Yes and No.

Some games will work whit JIT and some will not, similar problem whit real 68060 cpu's where games and demos do not work whit superscalar pipelines enabled.

Fusion running Mac Software on 68060 is rally bad whit superscalar enabled.

More games will benefir from JIT surely.

Having UAE integrated (just like Petunia) would be great,
even the libs needs a patch

Having UAE integrated

Do not count on it. It will probably never happen on OS4. This has already been discussed....

RunInUAE pretty much gives you the feal of UAE being integrated. Using it with EUAE with JIT will be great, all the old games/demoes and software should work great. Maybe some improvements of RunInUAE, like the option to install a P96 AmigaOS during install for anything that you want to run from workbench or as an option when you get a requester when you launch 68k software.

I dont know why anyone would want UAE integrated. I mean, system friendly applications run anyway and for games it is enough you can run it by clicking on its icon. I think this confusion is coming from AROS where you can not run system friendly 68k applications at all so UAE integration is more relevant there.

Any progress is good progress. I am looking forward to JIT in E-UAE, it really needs it.

All I have to do is double-click an icon and I have a full-screen Amiga 4000 (or whatever Amiga I want). I'm looking forward to the time when EUAE has the same interface as WinUAE. Setting it up is so easy.
