Trying to convert something to ASM6 - this is mostly just for future knowledge. I have the syntax bcs *+4, which I'm assuming based on the code is something along the lines of 'branch 4 lines'. I can handle this pretty easily with labels, but just curious if there is a reference to asm6 shortcuts to...

Yes - must've been a glitch in the Matrix. Working fine for me now too. Will check them out.

tokumaru - noted. Do you recommend your compression tool for CHR-RAM, before I go test it out? I want to sort of start there.

Thanks!

dougeff - yeah in most cases, that's not the case for our screens...but it's ok, I knew that would be a bit prohibitive going in, we made the sacrifice for the aesthetic and are still ok with scope.

Lidnariq - link is broken...

GG - I'll check that out!

So starting to get to the point where I want to start compressing some data; our nametables are so non-repetitive, RLE savings don't offer much, and I'm ok with that trade off...however, I definitely want to try to compress the CHR-RAM and see what sort of saving I might get there at least. Likely m...

Yes - it seems making all vars 16bit vars was the easiest solution: LDA tileRow CLC ADC #$20 STA tileRow LDA tileRow+1 ADC #$00 STA tileRow+1 LDA tileStartAddress CLC ADC tileRow STA tileAddress LDA tileStartAddress+1 ADC tileRow+1 STA tileAddress+1 So far have given it a pretty good test and looks ...

So just trying to condense down some code and stumbled on a little issue with a carry value not working like i though it should. Thoughts on this? ;; a 16 bit variable for tileAddress - this is the address at which a tile will change ;; an 8 bit variable tileStartAddress that correlates with the low...

Hey there - thanks! Just seeing this...haven't been actively looking at this thread. I thought I got everyone added in, but it seems I missed a few in each category. Been quite an adventure with so much to keep track of! Make no mistake, in the film, all will be credited. I will try to adjust the si...

I think this post is long overdue, and I don't know where else on the page to put it, so I figured I'd put it here. I wanted to just post a blanket, long overdue 'thank you' to the NESDEV community - those that trailblazed this path and did all the grunt work to reverse engineer this beast so that w...

Thanks for all the help guys...so far, no such luck. I've checked to make sure how everything is set up. Location of ram variables is 00, three free bytes (other zero page vars start at 03). Completely just took over a chunk of memory ($0600) that is not being used by anything else (also, tried swap...

That is what I thought...wanted to make sure before I went needle-in-haystack searching.

Thanks.

Famitone 2. It's something in the engine then, not FT2.

So, learned the very basics of Famitracker a while back. Snapped in some a simple tune as a placeholder just to get Famitone implemented and working in the engine. Well, the other day, sat down to really learn all the nuts and bolts of Famitracker. Made a gorgeous piece that I was really happy with....

**Solution** My NMI was running a routine for loading background palettes from RAM variables, then immediately following, sprite palette from RAM variables. I was writing bck from #3f00-$3f0F, then writing sprite from $3f10-$3f1f...meaning my background color was being 're-written' when writing the ...

Right that was just a mistype into here. Im loading palette variable from a series of Ram variables during the NMI. It's working fine. I routinely have the palette changing, but to this point, bck has always been $0f. For a new palette I was attempting to change the bck color, but changes to the RAM...
