Re: OPEL Software for the Oric

Yes, and that's why there are these IRQ_START and IRQ_END things, I wanted to show an example of doing that 100% in C, which obviously is not recommended because of performance reason. What these macros do is just that: #define IRQ_START asm( \ "..." " bne copy_loop\n") #define IRQ_END asm( \ " ......

And what's more amazing is that source code is available. :shock: https://...

Re: lda simplification of relative y index value ?

Please, stick to English, other people can benefit from that! Yes sorry, I was just saying that, unlike structured languages, assembly language doesn't make it possible to use arithmetic expression except for expression involving only constant values because such expression can be evaluated by the ...

Re: lda simplification of relative y index value ?

lda (sprite_address),y-3 Cette instruction n'est pas possible en assembleur. Il est possible, en certaines circonstances, de mettre des expressions arithmétiques dans des instructions assembleur. Par exemple: __auto_1 lda $245 sta jmp_old_handler+1 __auto_2 lda $246 sta jmp_old_handler+2 ou bien: #...

Very valuable contribution
