Re: Was the GBA's sound worse than the 8-bit NES's sound?

We have an old thread about it. Lidnariq's first reply does cover it pretty well I think: http://forums.nesdev.com/viewtopic.php?t=19688 Bregalad had linked a few demonstrations in that thread but unfortunately the links no longer work. :( I do think a lot of the common reason that GBA soundtracks h...

Re: Amount of BG tiles used in 8-bit and 16-bit video games

I don't know if I should cram the haunted house tile set in with the city tile set or use a "split bank" approach where I have, say, up to 512 tiles shared in both level 1 and level 3, and have 512 tiles unique to both levels. From the numbers I'm assuming you're talking about SNES, but I'm not sur...

Re: What keyboards do you use for programming?

Unicomp still makes the classic buckling spring Model M keyboards they used to build for IBM, except they have a modern set of keys and USB support now. I have one and it's my favourite keyboard for typing work. However, it's quite noisy, so I normally have to have headphones on or the volume up to...

Re: Sound FIR Boxfilter Question

Yeah, the noise channel will never sound right unless the high frequencies are accounted for in some way. Averaging them is pretty good for that. For a simple but pretty good sounding setup, I've used this in a few projects : 1. Sample most channels at 192kHz (4 x 48kHz), but for the noise channel t...

Re: Sound FIR Boxfilter Question

This reference might help with implementation: https://www.dspguide.com/ch16/1.htm The actual sinc filter with ideal response requires contribution from infinite samples before and after the current time. To make it more practical, its common to use a "windowed" sinc filter. This takes the sinc shap...

Re: Experiencing a real development of a Nes cart with 80’s computers

I've also heard of Atari ST, PC88 and PC98 being used to develop NES games. There's a story about the first Kirby GB game being largely developed on a Famicom Disk System with a custom trackball accessory . You could really use more or less any computer that was available at that time to make your g...

Re: OverlayPal: A graphics tool for automatic sprite overlay creation

In my own work I've done semi-automated solutions for this a few times. What I tend to find most useful is a tool that does the automated part in a simple/predictable way, and then has a way to look at the result and manually give hints to it. "Start your row of sprites here. Come from the left inst...

Re: FDS header date fields

Slightly offtopic for this thread, sorry, but "dumped it into a disk", how do you do that the easiest way? What kind of hardware is required? I think Loopy's FDS Stick is the easiest way to interface with an FDS these days. You could run a disk copy utility from it and do some swapping with a real ...

Re: NFT/Blockchain ROMS

Will others continue to invest? I'd bet heavily on no. This will be a short lived fad. People who bought in will soon have a realization that nobody cares about their NFT and they're not going to hold any value as time goes on. If you just want to support an artist, you can do that really easily an...

Re: NFT/Blockchain ROMS

It's just a "receipt" that says "this data was sold to this specific person". The data itself is easy to copy, but a person can prove the paid for it. This receipt is also transferrable. Who is this valuable to? Have you had a problem in the past where you've made a limited edition NES ROM, sold it ...

Re: Do colored borders bother you?

I especially remember TMN(H)T to have lots of garbage at the bottom of the screen, and I wondered what it was and why it had to be there. It sets the scroll to what is effectively -8 from the top. I think this is basically a convenience so that on NTSC you can put line 0 of your nametable at the to...

Re: Do colored borders bother you?

The preferred solution would be to tune an appropriately shaped display so that pixels fit it (and I was under the impression overscan was and still is more likely than underscan). I think the left and right edges of the picture are at least partially visible on a lot of CRTs that are properly cali...

Re: Do colored borders bother you?

Clash at Demonhead and also TMNT and Alfred Chicken (probably others) all use a column of black sprites on the right side, but I believe it's to hide attribute/nametable scrolling seam glitches when scrolling horizontally with a vertical nametable arrangement. Not really the same problem as colour 0...

Re: Do colored borders bother you?

Yeah, this is a big reason I'd be likely to take black as the background colour even in a blue-sky area of a game. I do find it rather distracting in cutscenes for Ninja Gaiden or Gimmick!. It's extra jarring on modern TVs where generally there is additional black on the sides to pillarbox. Like New...

I understand that 6502 is not particularly happy to process arrays of structs...
It does relatively well with a struct of arrays, though, e.g.

Code: Select all

struct {
    char a[25];
    char b[25];
} soa;
