Re: Oric Atmos Won't Initialise

Help with a "Your computer" program

I found an excellent utility in Your computer magazine December 1984 issue "Oric Sprites" As it was described, "Sprites will work in Text mode, but one pixel movement in every direction" http://puu.sh/CIQCI/e2e89f9781.jpg http://puu.sh/CIQET/71c890f6c2.jpg The usage is well documented and Eventhough...

BASIC 10 liner contest, Anyone?

There's a competition for retro computer users. You are required to write ten line basic program. Maybe an Oric coder wins :) I just wanted to let you know about it. Of course our programs will be on PUR-80 category. Maybe interesting projects would be developed. What do you think? "Already a tradit...

Substraction and Addition

I always find it hard to understand how aritmetic operations are done with machine code. I have a question with 2 byte substraction. Before that, I will try to explain What I do for 1 byte substractions and additions for future references. Actually, as I previously stated in different topics here, I...

Re: Competition CEO: New Year 2019

Same here.. I can't bring the things in my mind to the life..I am stuck with some machine code routines. There are some projects I started but none of them seems to be going to finish. I hope I would finish something worth to share but probability is still low, and time is running fast...

Re: Port Crazee Rider?

Regarding to curving, I made a simple program to calculate and draw "road pavements" by using bezier curve formulation between two points.. Its written in basic, but maybe it gives an idea how to draw a road.. What does this program do? It calculates the points between starting and ending coordinate...

Re: Port Crazee Rider?

My mind is confused on step of giving curve to the road. Calculating sin waves? bezier lines? I read many sources about race game road making and I can't imagine still how they do it, especially under limited power. Some of these sources are ; https://codeincomplete.com/posts/javascript-racer-v2-cur...
