In short, sounds like you shouldn't be using BMI. You are checking the N flag. Don't you want to check the C flag?

Yes, completely. There would be no advantage to using it beyond preference in the source assembler file. I don't know 65816 code so I am going to leave this thread now.

This is all good knowledge about ca65, however none of that addresses (see what I did there?) the fact that D is relocatable on-the-fly. This I know. If you are only going to access things with direct page mode, then I (assume) you can do something like: .segment foo:direct and any references to sy...

Ca65 could benefit from better documentation, but from the docs: (note bolded text): From: http://cc65.github.io/doc/ca65.html#ss11.92 .segment ... "absolute" means that the is a segment with 16 bit (absolute) addressing. That is, the segment will reside somewhere in core memory outside th...

BTW another game that uses this (I think with sprite 0 for timing): https://www.youtube.com/watch?v=geHAoWQGSfI
Changes palette at the status bar, obvious glitching. Maybe turn off your sound before clicking that link though.

Based on the filename, this is the forbidden image:

But extremely accurate. The modern workplace is all about self promotion/preservation and politics, while actual productivity suffers. There are exceptions, but as a company grows it become inevitable.

Looks like my code is: newlyPressed = (currentButtons ^ previousButtons) & currentButtons Is that still the same? Anyway, I knew there was a better way to do it and will probably change my code to use the method thefox posted, just haven't looked if it will break 'releasedNew' even though I am n...

Something like a fire action would suit a newly pressed button. (Fire balls in Super Mario Bros.) Movement would work for a button that was held down. (Left or Right). ;ca65 code: .pushseg .segment "ZEROPAGE" pressed: .res 2 ; new this frame - held down pressedLastFrame: .res 2 ; last fram...

If you write the whole PPU palette at once, the only thing that matters for setting the background is the write to $3F10. Other writes don't matter as far as what is displayed for the background. I would also suggest not reading from the PPU, just shadow everything to RAM first. My code always write...

Your question is not clear to me.

What is returned to high? .. Edit.. Bregalad's answer is better and makes the most sense based on what your question must mean.

Small suggestion:
Use a ROR then branch on the carry to check bit 0. (Unless it helps you later to have the result of that test in the accumulator.)

That was fun (family members here were freaking out over the poor ponies) but too easy. I beat the game my first try.

I wasn't a kid when I played it, but I played Doom 3 with the lights out and the sound up.. fun but terrifying!

When I was somewhat young, D on 3do was frightening.
