A little teaser of things to come... (took me just 30 min to get it working on the Oric, thanks to 8bit-Unity)
Have a good week everyone, and see you again next week-end!

Thanks for the encouragement buddy! I worked all week-end on porting 8bit-slicks (my racing game) to the Oric via the 8bit-Unity SDK.
I have now a working prototype, though the frame rate is a bit slow (~12 FPS). Gonna try to improve things a bit before I post a demo disk here.

To keep things fresh, here goes a roadmap update on the next versions 0.2 and 0.3:

Thanks for the heads up Targhan.

I will wait for your release in 2 weeks and minimalist player, and see if I can have a crack at it. Will you release the documented asm code for this new player?

Something which really could help (on all platforms), would be to have a fully documented reference player written in C. I second that! a C player would be easy to improve once it has been compiled to 6502 assembly language. Out of curiosity, just how big is this Z80 player? Does it badly require i...

Hey guyz,
It seems that this thread went cold, but I would like to resurrect it and ask if anything has been done about coding a small footprint player for the Oric?
I have been looking around for a cross-platform tracker for 8bit-unity, and Arkos looks like the stuff of dreams!
Cheers,
Tony

See there ;) http://forum.defence-force.org/viewtopic.php?f=25&t=1916 Awesome! Looks like all my code so far runs on both Oric-1 and Atmos, just by adding this code: // Switch to Hires mode if PEEK((char*)0xC800) { asm("jsr $EC33"); } else { asm("jsr $E9BB"); } (I will keep ...

That sound promising! By the way, is there a useful register that can tell me whether I am running an Oric-1 or Atmos ROM?

(sorry, my cellphone created extra posts which I can't delete)

I have a technical question: cc65 only has a profile for the Atmos. I tried running atmos binaries on oric 1, and found that text works but not hires.
What are the differences between oric 1 and atmos, from a programming pov?

Wow, looks so cool .. I can't wait to play it! :) For now I am concentrating on 8bit-unity, my cross-platform game SDK (which people can use to develop games). But once that is done, I need to progress on the 8bit-Hub project to have an ethernet adapter for 8bit-Slicks, so it can be playable online.

Progressing quite fast now, I got the text printing functions and sprites mostly finalized.
Next will be sfx/music and joystick (any resources online on how music tracks can be programmed??).

I am posting the current 8bit-Unity demo DISK, just to keep you updated...

I managed to reduce attribute clash by applying sprite INK only every two scanlines. I feel that the result is not bad, not bad at all!
I might leave it at that for now, and concentrate on getting the rest working...

I have just seen the video and am blown away by the sprite animation Twilighte achieved.
Was the code for the OType gfx made available? Or do any other Twilighte game contains the same technique and has code availability?

It took a bit of effort and thinking, but I finally got the demo working with AIC mode. To reach this goal, I generated a custom GIMP paletter (with 19 colors) and a python script (~90 lines of code) that will convert the 19 colors image to AIC pixels. I will include the palette and python converter...
