Want to try Oric-1 demo

Hello everyone,
I want to make some demo on my Oric-1. I have only the rom 1.0 basic rom now (I will look to put the 1.1 from atmos) so I have to use ASM or basic code for it I guess. In fact, I've looked for the C programming tools but the documentation explain that the code can only run on a atmos rom.

So to do it I will use some basic code. Their is no problem for music but I have a problem with pictures and animation. Can I make it easily with basic code? Perhaps using somethings as array or stuff like that?

That's actually not exact.
The code will run only on Atmos if you call the system functions like "Paper", "Hires", "Text", etc...
It's perfectly possible to either:
- Replace the hard-coded addresses to point to the Oric-1 rom equivalent if you know it
- Have your own code doing the same thing without calling the ROM at all.

Give a try at the OSDK, just change the values in %osdk%\lib\graphics.s to point to the correct values (there are some others in 'header.s').
Actually, if you manage to make an Oric 1 version, you can send me the files later and I can make the OSDK both Oric 1/Atmos compatible :)

You may be interested by the fact we have a demo project for 2013, related to the 30 years birthday of the Oric: If you can make some model agnostic demo effects, I would gladly add them in the Oric 30 years demo.

It would be more easy in this case. I've look, I have some value to modify so now I would try something with the OSDK and after make it for my oric 1 by modifing the value.

For the demo, I will try to make something, but I can help you for it without any problem even if I am really on the Oric demo scene and demo scene too :wink:

Hi everyone.

After some work I've made my first "demo" on Oric (also my first on any system). It's an atmos demo.

It's without music except a explode sound.

What do you think about it?

Cool! I like the color swipe effect, it'd be neat to see a full game use this somehow in its art as a feature .. nice work! Assembly/Basic/C?

Thanks for your support.

I will try to make a bigger demo with music and send it before the end of the year :D
