when starting euae i see the processor load go up to 100%. euae seems to run. but when i quit it using ctrl+alt+q the cpu load stays 100%. scout tells me that there still is the sdl task running.
is there a known problem?

There is a known bug with hardfiles which stops E-UAE quitting cleanly on AmigaOS. I have fixed this problem now, though, and am hoping to put out a new release very soon.

right now the uptime of an os4 machine doesn't exceed 3weeks in very exceptional cases.. for standard uses and users, it's rather few hours, or if lucky few days (2~3days)

I'm not sure uptime is relevant for anything other than a server.

I can actually get good uptimes out of my A1, when I'm not debugging code at least. When I was crunching RC5 keys on it a while back, uptimes of a week or more were not unusual. Then my desire not to waste electricity became greater than seeing OS4.0 rising in the RC5 stats...

The only reason this Linux box I'm typing on has an uptime of 4 days is that it's so excruciating slow to boot that I'd rather not wait around for it to boot up when I'm pressed for time - so I leave it on.

Except for floppy images such single partition image files don't make any sense to me, especially if they always use FFS and you can't select the DOSType of the file system.

Actually you can use other filesystems than FFS. E-UAE can load an external filesystem handler and use it to mount a hardfile.

You specify the path to the handler to use as a parameter to the hardfile2= option (the handler binary must obviously exist somewhere in your host filesystem). If you don't specify a handler, the version of FFS built into the kickstart ROM is used.

For example:
hardfile2=rw,DH2:/home/evilrich/hardfile.hdf,32,1,2,512,0,/home/evilrich/SmartFileSystem

Just checked this right now, and I did find one problem. I had a filesystem-style hardfile mounted as well an RDB one, and HDtoolbox hung on the former. If you run into this problem, you may need to temporarily disable any filesystem-style hardfiles until you've partitioned your RDB one.

Actually, the problem is more serious than that. There was a race condition in the hardfile code. I've fixed this now. See
this mail for a patch. The fix is also in CVS.

For those who don't want to build from source, I plan a new binary release in a few days containing this and other bug fixes.

I'm still keen to know how to make an RDB image.

Create an empty file of the desired size. For example:

dd if=/dev/zero of=~/hardfile.hdf bs=512 count=163840

would create an 80MB hardfile called 'hardfile.hdf'.

Then add the option:

hardfile2=rw,:~/hardfile.hdf,0,0,0,0,0,

to your E-UAE config file.

Note that you don't specify a device name or geometry (this info gets stored in the RDB when you run hdtoolbox).

Before you can use an RDB hardfile in AmigaOS, you need to initialize it then partition it with HDtoolbox or similar - just like you would a real disk. Get HDtoolbox to scan uaehf.device.

1) How many can E-UAE support in one configuration?

Up to 30 hard files and/or virtual filesystems combined are supported.

Quote:

2a) What is the largest size file it can support?

On systems which only support 32-bit file sizes, the maximum hardfile size is 2GB. On Linux, there is no practical limit, however. I suspect the limiting factor would be the maximum number of cylinders that AmigaOS supports in a disk. I'll need to check that.

Quote:

2b) What is the geometry for this size disk?

The size of a disk is defined as:

size = block_size * sec_per_track * surfaces * cylinders

Block size is typically 512 and common practice in UAE is to set surfaces to 1 and sectors per track to 32. Then for a given hard file, UAE will work out the number of cylinders based on the size of the hardfile:

cylinders = size / (512 * 32 * 1)

The next version of E-UAE will include a makedisk tool to simplify the process of creating hardfiles.

Quote:

3) How can I make a disk file which appears in the HDToolBox?

Do I have to use RDB disk images? I couldn't find anything particularly useful with creation of such.

Yes. RDB hardfiles are partitionable with HDToolBox.

indeed I can load a savestate with CTRL+LALT+F5 but CTRL+LALT+F6 does not seem to work to save. There is no requester asking me where to save and under which name (in contrast to load savestate).

Oops. That should have been Ctrl+LAlt+LShift+F5 for the save state requester.

Many thanks for your continuing efforts to improve EUAE.

You are quite welcome.

It's something I really enjoy doing in my spare time. I just lament that I often don't have enough spare time to do the work that is required to do the project justice.

One of my main motivations for working on E-UAE at the moment is my children. Yeah, I know, it might sound strange, but I'm getting my 6-year-old daughter, Eilidh, and 5-year-old son, Caelan, hooked on classic Amiga games. 'Lemmings' has been a big hit with them both for a long time, but at the moment their favorite is 'Marvin's Marvelous Adventure'. Caelan also loves 'Shadow of the Beast', but it's too difficult for him at the moment.

Anyway, as you can probably imagine, I'm thinking a lot about ease of use at the moment (so I don't have to be on hand to load games for the kids, etc.). It's a long way off, but I'll get there eventually.

Rich

i get linking errors

When linking against static libraries, the order in which you link them is important. You're linking against SDL and SDL_mixer in the wrong order. SDL_mixer uses functions from SDL, so you need to specify SDL_mixer first.

For example:

gcc obj1.o obj2.o obj3.o -o my.exe -lSDL_mixer -lsmpeg -lvorbisfile -lvorbis -logg -lSDL_image -lpng -ljpeg -lSDL -lz -lm

Press Ctrl+Left Alt+F1 to open a requester that will allow you to pick an floppy image to mount in DF0:.

You can also specify a floppy image on the command-line with the option -0 (that's a zero). For example:

uae -0 some_floppy.adf

The other alternative is to use the option 'floppy0=' in your config file.

Saved states should already work.

In the AmigaOS versions, use Ctrl+LAlt+F5 & Ctrl+LAlt+F6 to load and save states.

No other platform supported by E-UAE has the saved state dialogs implemented yet.

Great! Any big news/dev update to inaugurate this forum?

Yes. But probably not the kind of big news you'd like.

The last public release of E-UAE, version 0.8.29-WIP4, was rather buggy. Yeah, I know. Insufficient testing, real life, yada, yada. More specifically, when I revised the emulation of the interrupt controller that is built into the Amiga chipset for WIP4, I fixed a couple of things, but broke a whole pile more. In short, compatibility suffered.

Anyway, I've solved that problem now, and I'm hoping to release WIP5 to fix this and other problems ASAP. If you have any bugs that you want to report or to remind me of (if you've reported them already), then now is a good time to do so.

I am also working on bigger things besides bug fixes, but I don't want to say too much about that right now.

Tell us more! Any fixes to the GL parts?

Tell me what you want fixed.

Support for GL surfaces in a window will be added soon. Apart from that I don't know of any problems with OpenGL support that are fixable within SDL itself.

The problem you mentioned to me in that email about linking against OpenGL is not a problem really. You don't need to, and, in fact, currently shouldn't, link your app against OpenGL - that is, don't use -lGL

libGL.a just opens minigl.library for you. It's not needed because SDL does this for you. At the moment, linking your app against libGL.a may mean that SDL and your app don't end up sharing the same GL context. I suppose I should add some checks to handle this just in case the developer insists on doing -lGL despite the fact that it's not necessary...

SDL on OS4.0 does work in windowed mode. It's just OpenGL surfaces that are currently unsupported in windowed mode. That'll be fixed shortly...
