Re: C/ASM profiling tools?

I've posted a follow up article on the same topic, with some concrete example of how to optimize code:

Re: List for Microdisc controller + Amplibus, LAST BATCH.

I think the confusion is that there are two threads, and people did not get any answer on that one, I can lock one of the topic and point to another one, just confirm me which one.

Re: C/ASM profiling tools?

Since the topic has gotten some attention, I decided to spend a bit of time writing a blog post about it: http://osdk.org/index.php?page=articles&ref=ART11 If you are interested, the code of the "racing game" prototype with the integrated profiler is on the SVN depot: http://miniserve.defence-force....

Re: Oricutron 1.0 (EDIT: Now 1.2)

Question to the Oricutron people :) The current "Official" version is still 1.2, dated from 2014. Would it make sense to make some official new version? Basically I'm trying to update the OSDK documentation with an article about profiling, I wanted to add the section from ISS about the Cycle Counter...

Re: Filepack support request

I guess I could add a better diagnostic message, but yes, basically if the end result does not compress, there's no point in packing it. Generally this happens when trying to compress already compressed files, FilePack is not designed in being the best packer, it's made to allow almost real time dep...

Re: Psycho III

That's kind of the problem of the Oric community: We have many motivated individuals, but it's more like a lose collection of people who sometimes meet here and there. I guess the CEO is most "stable" entity around regarding Oric stuff, and what was suggested requires a significant organization, wit...

Re: OricExos - making the impossible

I was wondering about the transportability of the device. To make it usable, it should probably not fall apart, and having a keyboard would probably also be a good idea. So I was wondering, why not make it in the style of the old Apple II machines. Take a Pravetz 8D, cut the bottom and and move the ...

Re: Wich scripting language for OSDK ?

Now, it will require quite a lot of work to change OSDK to be able to change existing scripts and plug a scripting engine I believe... I don't think that would require a lot of work, just some stuff on the side. At the core, in the OSDK you have separate folders for the libraries, macros, samples, ...

Re: Oric @DemoSplash party

And I suppose having your demo played on such a huge screen overseas must be a pleasant experience
It mostly made me think that maybe I should spend a few hours here and there to see if I can't get this damn fractal and end scroller to be faster, because they are painfully slowwwwwww.

Oric @DemoSplash party

This weekend there was a demo party at the Carnegie Mellon University in Pittsburgh, USA. http://www.demosplash.org Demo parties in the USA are not that common, but that one pushed the things farther than many, they did not manage to have real oldskool machines and show demos on them, including a re...

Re: Competition CEO: New Year 2019

Just to be clear, you do not have to use the OSDK: You can use any language, you can use native languages if you want, you can do BASIC, Forth , Assembler, C, Logo or whatever else comes to mind.

Interesting project, I need to think about it :)

Re: My first ASM and it doesnt do what I expect

Christian's answer is mostly correct, but he did make a typo in his code sample :D decrem sec ; Calc new display adress lda write+1 sbc #40 sta write+1 lda write+1 sbc #0 sta write+1 The two lasts "write+1" are supposed to be "write+2". Regarding optimizations, there are indeed many possible, like f...
