LiveForIt : Yes, DosBox uses interpreted emulation. There modules with dynamic emulation but only for x86 of course.

mufa : I will try with more apps, I had no crash here, until now. Maybe because I used the GCC option -O3 and it may introduce optimization bugs :) I don't know, just an idea. Don't hesitate to tell me which game crashes.

lazi : What is the average CPU consumption ? What hardware do you use ?
Thanks for the link on fastdosbox but at the moment I failed to get the archive (site too slow). I am curious about the optimization ...

I think it will be hard to optimize DosBox because the code is really hard to understand and it would need much work to clean it all. I have one or two ideas that I will try.

I've just uploaded DosBox 0.72 on os4depot, it should be faster. But it will be harder to optimize that I was thinking previously. But nothing is impossible.
I tested it on my ?AOne G3/800 with Kyrandia, Lost Vikings ... yeah !

@BillE

I understand your need and I suppose you will enjoy improvements in the next SDK. You're right to ask for this concrete feature.

Else, I agree with Rogue and Hans, I recently read on another forum the same questions about a new SDK. But once you ask for concrete needs, nobody answers. I think they don't know themselves what they would like to find in a SDK.

Hey guys, let's start. Don't be afraid ! You have a existing SDK, many libraries available, compilers and tools, support (utilitybase.com, MUI mailing list, ...).

To come back to the first post, I hope OS4 on Classic will bring new developers even if other hardware support will have a more significant effect ...

@orgin

It seems that you don't ask for a SDK but rather a full copy of OS4 and its SDK for a PPC emulator ...

If Hyperion was able to do that, it would be better to spend this time porting OS4 on various hardware (Sam440, Mac, LimePC, ...).

Maybe the same developers that already make programs for OS4 ? Who do still develop only for 68k today ?

Sorry to answer late even if I have a high interest about USB drivers, I am currently busy preparing the release of PointRider :)

@VooDoo
In the past, I tried to write some webcam drivers on MorphOS and OS4, looking at libusb too. But it failed because isochronous mode was not supported.
Pencam uses bulk and a driver would be feasible. The problem is finding old hardware like it.

Else I also have a serial-USB link with pl2303 and another one with an unsupported chip. At work we have many things that would be tested too.

I own several webcams and only one can be used with bulk transfers. I could try to use it but the webcam is not well documented.

For my personnal needs, I have a scanner AGFA Snapscan e25 and I plan to buy a new printer. For my camera (Canon PowerShot A560), I use directly the SD card.

Maybe in 2008 we will see open projects about USB devices on Amiga ?

@LiveForIt

If I understand, you want to port / implement GDK to compile the original GTK with a native GDK. I am not an expert (even if I tried to understand how to wrap GTK cleanly) but :
- GTK does not only depend on GDK (but you know that because you are talking about Pango and Cairo interaction)
- Gadgets are managed by the GTK layer and I am not sure about the result : in my opinion it will be necessary to change some parts of GTK too

GTK is a hard but interesting topic. Maybe I will have a look on it again.

@acefnq

Hehe, the log was quite long and I tried to extract the precious information from it. This does not indicates where the error comes from : only the author can really find the bug and fix it.

But you're right, it is important to report bugs ! Even if a forum is not the most efficient IMHO, it points the problem that can't be ignored ! It is far better than no report at all !

So prepare to send me bug reports on the next release of PointRider

I am not at home but I will update Yam and could try videotext datatype (I totally ignore where to find videotext files).

@acefnq

It would be better to send a report to the author, indicating steps to reproduce the bug.

It seems to be a null pointer bug :

*7f6ffb68: 801d0000 lwz r0,0(r29)

with r29 equal to zero. The program tries to read a value at address zero.

@AmiKit

This video is great ! I saw it in live at the recent show Alchimie 7 It was a nice surprise and if this kind of videos were done for other Amiga products, I think it would be much easier to convince old user for example.

I don't know if I will use AmiKit very often but I got a copy. Great work, AmiKit !

@AmiKit

George Clooney !

It was a great party ! With surprises as you can see.

ACube was there on sunday with the board. And we saw OS4 running on a A4000. We also tried it of course. For an AmigaOne user, it is of course slower but OS4 is there !

MorphOS 2 was running on Efika. We saw the great paint program written by Stefkos, Blender in action with Yomgui (the author of the port), Mame and mplayer with Fab, Sputnik, ...
Yomgui also shew a new project : a Python wrapper to write easily MUI apps. Personaly, I had PointRider running with its new features.

The new USB2 card was running very fast in the Voxel's A4000.

There were conferences : Thomson MO5 in a FPGA, OSS port to Haiku, AmigaOS4 on classic, Amikit (hey!), ...

So much things to say about this great week-end ...

I am not an expert at all about filesystems but as a developer I can say that the sources seem to be clean and the project very well designed, with OS specific parts isolated.

It may be easy to port for someone that know filesystems. Full and solid NTFS support would be really helpful.

@cygnusEd

Really great job ! I tested the previous version and it was a good surprise, now it can bring us many missing apps.

Thank you again I have now better results on PointRider (image and text rendering) and the next release will be much nicer.

@MamePPCA1

You could find advices on this page.

To swap to full screen mode, the special keys page tellls that you have to use alt-enter.

About speed, I looked at the sources yesterday and I suppose we can find many things to optimize.

If I had a driver to develop I don't know which would be the first step and where to find information. It would be nice to give more about driver writing under OS4 in the next SDK.

Why not an example for a simple PCI card ?

That's nice to read technical info here and ideas for the future !

rachy wrote a great answer, well explained. Of course, a system can work without memory protection but that would be ridiculous to make AmigaOS without memory protection. The MMU is here hopefully and we can (we must) use it.

And from a developer point of view, it helps to track bugs. Without MP, as rachy told, a buggy program can cause a crash later. How could we find the real cause in a such situation ?

Resource tracking allows the system to know each resources are allocated by each program (memory, files, devices, ...) so if the program crashs, the system can kill it closing all resources properly.

@Elwood

This is what I thought: if some people can do games with Hollywood, maybe it's possible to do GUI apps too. And this, without the need to learn C, Reaction...
Just a thought.
[/quote]

It is certainly possible (Hollywood is really powerful !) but if you want to write GUI, I think this is not the good choice (the same for RxMUI : great but not dedicated to GUI programming).

A nicer way would be to have GUI modules to program easily in Python or Ruby.

@Elwood

In the PointRider package, I can find the tool MeltingPoint that creates an Hollywood projects (generates a script and extracts images) from a PPS file. You certainly have some simple PowerPoint files to convert and see the scripts.

This article was published in January, before people know troubles between AInc and Hyperion. Of course PS3 could run OS4 or MorphOS ... this does not means it can happen with the current situation.

@Elwood

And what about the sg2's server AmiVNC on Aminet ?

I did not tried it. But I suppose it works and I can see sources are included in the archive.
