You realize Steam distributes Blender, right? They accept copylefted software just fine.

You could change up to 15 colours per scanline with HDMA How? I've looked into this before and I only found a way to change up to 8. I couldn't find a way to transfer four bytes to CGDATA per channel with HDMA. I did write a demo that displays 16 colors per scanline using a carefully timed hblank i...

No, I'm not confusing it with RCS or CVS. I've used SVN myself; in fact, I was responsible for getting a game company I worked for to use it. (Prior to then, they were using no version control at all!) But git seamlessly handles things that are a pain in the butt in SVN. I don't know, maybe SVN has ...

I feel SVN in any form is dated and should not be used for new projects. I mostly use GitHub for Windows with a little bit of TortoiseGit. I use github.com for projects that I don't mind being public, and bitbucket.org for projects that I don't want to be public yet. I should add that git is very us...

Just tested it myself; I believe it is correct.

6502.org says "A page boundary crossing occurs when the branch destination is on a different page than the instruction AFTER the branch instruction", which is exactly what this macro detects.

I did think of a reason to write to the regs in ascending order instead of descending: I forgot that the registers $4003, $4007, etc. can act as triggers, so you might not want to write to them until after writing to the other registers for that channel. Dunno if that affects how this particular cod...

Going back to the original post... I feel this "modular" approach to game design and implementation often leads to a game that feels like different games bolted together. That's generally not a good thing, if you ask me. I think games should feel like a sort of unified whole as much as pos...

I'd missed this post earlier: I bet this is why the comments about the purpose of the initialization values were removed, and also why it doesn't care about triggering a most likely harmless OAM DMA. This is a dangerous attitude to have. For one thing, if you're going to put up a message saying not ...

I dunno. I think a coder who is ready to really get into the nitty gritty like that should already be capable of working out what the code does as it is.

Yikes. I forgot $4014 is where the OAMDMA register is, just like the programmers before me. I'll bet that write to $4015 was because some earlier version of the code skipped over $4014, then someone didn't realize (or forgot) this needed to be done and added $4015 and $4017 to the table. OK, I fixed...

The code at http://wiki.nesdev.com/w/index.php/APU_basics#Register_initialization had this: init_apu: lda #$0F sta $4015 ldy #0 @loop: lda @regs,y sta $4000,y iny cpy #$18 bne @loop rts @regs: .byte $30,$08,$00,$00 .byte $30,$08,$00,$00 .byte $80,$00,$00,$00 .byte $30,$00,$00,$00 .byte $00,$00,$00,$...

Perhaps it would be clearer if you gave an example of use, instead of assuming we know what you mean.

Games for old consoles generally use the vertical blank (vblank) as a timer. The game executes a frame's worth of game logic and prepares the frame for rendering, then waits for vblank. This wait keeps the game in sync with the TV's rendering and also ensures that the game always runs at a consisten...

What's your bug, exactly?
