Re: Ways of implementing sprite animations
Hi excuse the query, but is it possible to make sprite data imported from JSON, ASM and/or C files? In this way one could convert the data of any game to a format that the application can read :wink: It's common to represent sprites in JSON or C structs. You have to write your own script to convert...

Re: Strategies for implementing macro functionality in assemblers
Everything depends on the semantics and evaluation strategy of your macro system. Typically though you would identify all the macro arguments before you expand anything. Everything that isn't a macro argument would just be strings to the original code. For example: .define FOO(X, Y) 3 * X + Y would ...

Re: 3d graphics, how?
Yeah it's pretty much just skewing the image by changing the horizontal scroll every scanline (a row of pixels). It's the classic background parallax effect.

Re: [Help Request] Animation Guidance
Sometimes it's easiest to tie the animation to the x/y position. You probably don't need tables/subroutines at all.
If you want it slower, just add another 'lsr' or whatever.
Code: Select all
lda player_y
lsr
lda #SPRITE_TILE_INDEX
adc #0
sta $200, x

Re: Making "Beautiful" Assembly Code
I can't tell if you guys are joking, but XOR is pronounced "ex or" becuase it an abbreviation of EXclusive OR. Maybe the hamburgers, bikinis, and gun rights are getting to my head but I think it's a reasonable name.

Re: Making "Beautiful" Assembly Code
Stick to the convention of 1 thing per line, whether it be an instruction, a label, or a macro invocation. Don't even consider condensing code.

Nintendo legacy console leak
Didn't see a thread so here's this news article... https://www.videogameschronicle.com/news/nintendo-has-reportedly-suffered-a-significant-legacy-console-leak/ Apparently it include some verilog and firmware code, which could be very useful to emulator devs. I guess for the sake of the site, nobody ...

Re: What are your favorite ways games have ended levels?
Bubble Bobble does a clever trick of animating the character moving between levels. It's not just for show though. It guides the player where to look at the start of the level.

Re: Extending the 2019 deadline - poll
Multi-cart prizes have been missed two years in a row and I don't think a multi-cart should be offered as a prize if it can't be delivered. Additionally, the website/organization has been sluggish to update. I'd like to see the rules+deadline posted in February or March, and have submissions ready t...

Re: Extending the 2019 deadline - poll
I was disappointed with the last two contests and their delays. The volunteers deserve cheer, but I think they have bitten off more than they can chew. My own motivation for entering is tied to my view of the contest and its prizes, which right now, is poor. I don't think I'll spend more than a few ...

Re: Extending the 2019 deadline - poll
I'm fine with this, but I don't think it will have much of an effect. Work often fills whatever time is allotted to complete it. You don't stop procrastination by adding extra time.

Re: NESASM question
In most assemblers you would write LDA #width
I'm guessing NESASM is the same.
