fs-uae - a new multi-platform amiga emulator for games!

[lesta_smsc]

If you don't need opengl or fancy menu, it might be work just making it basic - would make the emulator run faster in general too!

Yes - first find the 'crappy' computer! :P

No, this is not true: OpenGL does make it go faster -compared to many alternatives. There really is no other common multi-platform API which allows fast rendering offloaded from the CPU with fullscreen scaling _and_ allows you to synchronize to vblank intervals.

-And the "fancy menu" does not make the emulation slower since it is not rendered when it is not open.

My point was that I can use older OpenGL features to make it more compatible with older OpenGL-capable graphics cards and drivers.

[lesta_smsc]

Ah - that would be useful (for me!)... Not all clued up with these software issues, but presumably graphics card is ok as it runs emulation/amiga part just fine

Hey Frode

any improvements for USB joypads/-sticks on Mac OS X? Can't use my "NO NAME" joypad. In E-UAE it's no problem.

Frode! .. So happy to see your work.. Many thanks!!

Nice

Not only for you.

You can use any joystick/gamepad which is recognized by Mac OS X. You need to create a config for it -it is easy! -but the howto in the README wasn't that good.

I have improved the howto and put in on the web:

Hello Frode,

just tested OpenSuse 12.1 / German Keyboard Layout / fs-uae 0.911beta1

and besides of the special keys of my multimedia keyboard, it seems to work fine.

Thank you!
Peter

Hi,

after readind since some time here at the forums, I decided to register as fs-uae is really drawing my attention.
First of all, thanks for your good work so far. It is really fun using it, the netplay feature is a star!

But I'd like to understand why the performance of the emulation is not that good compared to WinUAE.

My system has a Athlon X2 240 CPU, so 2.8 GHz max per core.
I am running Linux Mint 12 and I tried both, the precompiled 64bit Debian package, but also a self-compiled version on my system.

With default values, the CPU usage while running Pinball Dreams (model set to A500) is roughly at 150-160%.

When I boot Windows and run the same game in WinUAE, the CPU usage is at roughly 30-40%.

Besides that, my oppinion is, that the same game runs smoother within WinUAE than in fs-uae.

Is there a good explanation? Or is my system setup somehow wrong possibly?


Thanks
Markus

With default values, the CPU usage while running Pinball Dreams (model set to A500) is roughly at 150-160%.

When I boot Windows and run the same game in WinUAE, the CPU usage is at roughly 30-40%.

First of all, comparing CPU usage on Windows and Linux isn't that straight-forward AFAIK. I believe Linux reports CPU usage relative to one fully utilized core (or something like that), while Windows reports CPU usage relative to all cores. In other words, utilizing 2 of 4 cores to the full would have Linux report 200% usage, while Windows would report 50% usage for the same load (I'm not sure this is completely accurate, but the point is you can't compare the numbers directly).

Secondly, it is important to have comparable setups. I assume you run WinUAE with A500 settings in cycle exact mode, otherwise it would not be comparable to FS-UAE's default settings.

But FS-UAE also defaults to syncing to vblank, and the OpenGL driver may use a busy-loop for this, which will burn CPU cycles. I do not think WinUAE does this by default, so use the following FS-UAE setting to make your testing more fair:

video_sync=off

There are other reasons that could affect CPU usage as well:

- Different compilers are used, which would have different optimizations (FS-UAE is not currently compiled with most aggressive settings: you could try replacing -O2 with -O3 in the Makefiles..)

- Differences in video drivers (OpenGL vs DirectDraw or Direct3D)

- FS-UAE does not share video/audio/input infrastructure with WinUAE, and it is of course quite possible what the WinUAE code is better optimized.

I won't question your ability to judge smoothness

Here are some points to test/consider:

- The operating system is not the same, therefore the process scheduler is not the same.

- Differences in video card drivers can affect smoothness.

- Emulation is not perfectly smooth anyway unless using 50Hz modes with full video sync (are you?)

- Are you using compositing desktop manager? Ensure you are running FS-UAE in fullscreen. A compositing mananger and FS-UAE running in a Window will force the OpenGL driver to do indirect rendering. On Linux, if the default FS-UAE fullscreen mode does not work properly (does not cover the entire screen), you can use fullscreen_mode=fullscreen (the default is fullscreen_mode=window, which uses a fullscreen window -not all window managers like this, but it allows alt-tabbing etc).

- What graphics card/driver do you have? I have actually a smoothness problem myself with a (fast) computer with a recent nVIDIA card and newest nVIDIA drivers (on Linux). It does seem like a driver problem -vsync is choppy, but it runs fine on the platforms *and* runs perfectly smooth on a slower Linux laptop with an older embedded nVIDIA graphics card and older nVIDIA drivers. I haven't had time to investigate the Linux/nVIDIA problem properly.

To get a more fair comparison, you should run FS-UAE also on Windows on the same computer with video_sync=off (if not using full vsync @50Hz on both WinUAE and FS-UAE).

Not on Intel 945 chipset / OpenGL 1.4 compatibility yet, no :-/ -I have been quite busy with work lately. But I have an almost complete implementation of custom input mapping support (map any key/joystick button to any Amiga key/joystick action)

Thx Frode, i have tried any ostic game in hdf mode, "Super Street fighter II" installed on hd now work without freeze.

In the meantime i've updated the frontend, unfortunately i don't have much time to implement everything i wanted.

- Added net options (not tested)
- Added a way to auto-create a temporanty file config to test the emulator and settings.
- Added all options from FS-UAE.
- Can select a saved config from a combobox

G-FS-UAE source and packed distribution at Sourceforge

[FrodeSolheim]

* Floppy swapping is performed synchronized in net play mode.
* GUI Reset action can be used with net play.
* Save state saving and restoring is now synchronized in net play mode.
* Parallel port joystick emulation (joystick_port_2, joystick_port_3).
* Reduced input lag in net play games.
* Custom gamepad/joystick -> action mapping.
* Custom keyboard -> action mapping.
* Support mounting zip files as (read-only) volumes.
* Read command line arguments earlier (fixes a Configurations dir issue).
* Renamed "amiga_joystick" config value to "dummy joystick" (more descriptive).
* Renamed "amiga_mouse" config value to "dummy mouse" (more descriptive).
* Floppy speed setting was already implemented, but not documented.
* Finally implemented the volume mute function for OpenAL.
* Detect refresh rate properly on Mac OS X.

(Documentation for custom input events -> actions mapping is not written yet)

Hi, I checked the tarball, and it seems to compile cleanly. Perhaps you have extracted over an old existing build directory, and this has caused libfsemu to not be compiled completely? I suggest deleting the directory /home/Peti/Downloads/fs-uae, and then extract and compile fs-uae source.

[AmigaOnline]

Hi Frode!

I've tried the well known Dyna Blaster, and i just can see a weird screen (only in game). Do you have any idea how to fix this issue? (A500/kick1.3/default ram settings but it's the same problem with chip_memory = 1024 / slow_memory = 512).
This game usually works using most of the Amiga emulators
Thanks!

I did not manage to reproduce this problem (worked for me). Could you post config file and log file (and checksum of floppy?)?

[FrodeSolheim]

* Fixed a bug where large positive mouse movement became negative.
* Event information is written to Synchronization.log during net play (this file can be quite large) -cannot be disabled yet.
* Include slow memory in memory checksumming (chip + slow, now).
* Replaced a busy-loop in net play with proper condition signal/wait, using significantly less CPU now.
* Fixed a race condition in the net play server where input events could be sent to some clients out of order (with regard to frames). This would have caused desync when it occurred.
* Fixed a bug in the net play server where input events could be sent to some clients before all clients were connected.
* Detect refresh rate properly on Mac OS X (was not included in 0.9.11beta2).

Version 0.9.11beta3 can be download here: http://fengestad.no/wp/fs-uae/download-beta

For net play, this version is incompatible with earlier FS-UAE releases, and also requires an updated server: http://fengestad.no/wp/fs-uae/net-play
