Big E-UAE JIT blog

Alladin run slow... 203/23 ...
But i tested another game "trauma zero" it is much much better compared with the old Euae version.

@tlosm

Ok kas1e try this configuration and let me know how Alladin Aga Run on your peggy

cpu= 68020
Fullscreen 320x256
Immediate_Blits=false
gfx_framerate=1
Cpu_speed = 3

On Xe 933 with this configuration Alladdin Aga working much much better im sure on your Peggy will run like a real amiga ... if not upgrade it to 1,266mhz :P




Or you can try this configuration

cpu= 68EC020
Fullscreen 320x256
Immediate_Blits=false
gfx_framerate=1
Cpu_speed = real

on Xe is better this compared with the other one

@kas1e

Yes, Pulse makes a huge use of CPU power so the demo runs nicely on my AmigaOne XE G4, much better thant with the non JIT one.

@tlosm

You should read the readme. OS 3.9 will crash. FPU is emulated (but doesn't use the JIT, it's still using the interpretive way).

For information I use a 720*568 screenmode withe E-UAE.

@tlosm
I already tried a lot of options to make aladdin works fast back in past. Only way for peg2 is set frameskip to 1, all other settings didn't make much difference for that game. Without frame skip its slow and music jerky, and does not matter what else you set (other settings may do a bit of change , but nothing radical to make it works on peg2 without frameskip).

If with Jit there is no changes, then sad. But i will test it all myself later to be sure.

@kas1e

Sorry, just tried Aladdin and still really slow. I think Aladdin make use of the specifics of the AGA chipset and so won't really benefit from the JIT which acclerates only the CPU

@K-L

Oky :)
for now the best thing is fix the input typematic because is a really big problem when is needed use the keyboard

@kas1e

kas if you use my options and put the frame skip to 1 the game become little not playable ...

... im sure with the next version everything will be better ;)

@K-L
Yep, that what Rachy says some time ago: some games/demos/apps can just have no differences with jit because of heavy usage of chipset. But if i remember right (can be very wrong and just mess it all in head after many years), that when winuae reach level of usability and x86 jit was on the way to be finished, i compare Aladdin with and without jit, and with it it was faster. But can be wrong, and can be all kind of other stuff involved.

Btw, interesting how will all those old-good demos works now with jit like Relec, TBL ones, and 68k ones from Potion before they switch to ppc..

@all

Someone try adf games ?
For me don't works any game in adf format.
When I run, opens the workbench from RuninUAE, and a little window shows "run c".
And then the system hangs.

Ed. Solved, my mistake, I changed the default tool of the .adf def icon.

Now works fine.

@MickJT
Thanks,
In fact, RuninUAE was loading another config file... Now, everething is ok

@pseudaxos

No probs! :)

@tlosm

How can i run UAE in specific resolution?

My screen is 1600x1050, and uae is so small.

There's a way to choose a 640x480 windowed or full screen?

Thank you

@AmigaBlitter

What system do you have?
because if you have an old Ng ... will be more simple
different is with an RadeonHd machine equiped...
Are you running it tru RuninUae?

@tlosm

I have a Sam@667 with integrated Radeon.
Yes, i running through runInUae.

I simply copied the new jit executable into the directory where previously normal uae (used by runInUae) reside.

This new version, lack of the ctrl+ alt + s key combitation to choose some kind of screen.

@kas1e

Will it be possible to emulate those AGA 060 Demos you mentioned like Relic and Silkcute and demos like that? How feasible with UAE JIT on peg2?

@magnetic

The big problem is No fpu and no mmu ... You will have for sure more MIPS compared with a 060 50 MHz but all integers...
Plus everything depend how e demo is programmed... For sure the rtg demos will run great but have to run without fpu

@tslom : Incorrect : FPU is supported but not JITed (ie it is in interpretive mode).

From the Readme (that anyone should read) :

The following instructions are planned, but not implemented yet for the JIT compiling at the moment:

(...) - the FPU instructions were not implemented yet, these are coming at a later stage of the project.

@AmigaBlitter

If you only copy the new UAE over the former one, it won't activate JIT. You have to modify your .uaerc file.

@Users

Read
The
README !

@AmigaBlitter

You need to make a 320x256 with Picasso96 settings in prefs
Make 8/16/32 bit resolution ..
Copy this in run-inuae
# UAE config for RunInUAE, which is designed to modify an existing working UAE config

# Use 3.1 Kickstart for Workbench, but allow ADF-booted games to still use an older Kickstart
kickstart_rom_file=kick3.1.rom

# Emulate an A1200, but still allow A500 emulation for ADF-booted games
enable_jit=yes
cpu_type=68EC020/68881
comp_constjump=yes
comp_trustbyte=indirect
comp_trustword=indirect
comp_trustlong=indirect
comp_fpu=yes

cachesize=16384
cpu_speed=max
chipmem_size=4

chipset=aga
collision_level=none

# Emulate an expanded A1200 with 8MB of Fast Ram!
fastmem_size=8
z3mem_size=8
# Set frame skipping (1=show all frames, 2=show every 2nd frame, 3=show every 3rd frame, etc)
gfx_framerate=2





After launch runinuae and in menu bar select 320x256 fullscreen

Close rununuae reopen runinuae

After launch a whdgame ... Let me know

@magnetic

If they are whdload versions then they will work, but I don't think the JIT will work with whdload as it turns off cpu caches and thus the JIT will be disabled.

@K-L

I know the 68881 are not jit but are interpretate ...
but is better have the 68881 in the emulation because some software need it for run... eg some games like quake or doom need it for start running.

... when os 3.9 will be ready to work with jit i will make some other test :)


the Xe 933 sysinfo jit result :P




edit a not jit photo :)
