Sure, you can use the code as you wish.
By the way, I don't know if it's of any use, but I once wrote an NSF player for the TurboGrafx-16, which is kind of similar to what you're doing here (except I only I had to deal with emulating the parts necessary for NSF playback - not the entire system).

IIRC it was _mic who later released a sound emulator showing you can get a cleaner sound by using a set of larger samples played at the highest rates possible, as it will be affected less by the interpolation. Right. I did that in my SN76489 emulator for the SPC-700 ( source here ). When the target...

This remains me of the NSF player for the SNES which had very cool vizalisation If you're thinking of Memblers' NSF player, then yes, it was really cool. Why did you target the GBA in particular ? It's one of a few systems that are powerful enough for this to be doable, but not so powerful that it ...

Also, the sweep generators are currently not working correctly.

I think I've fixed that now. I had forgotten to write back the updated divider's period after decrementing it.

Link to the .GBA file Link to source code This is a small project I've been working on off and on for a while. I wanted to write an NSF player where everything was emulated on the GBA's ARM CPU, rather than relying on the DMG/CGB-compatible sound channels for some kind of HLE. I also wanted to expe...

Oh right, I have one of those. So you've extracted the 512kB block that contains the menu software from one of those carts, and now you want to try to use it on some other flashcart that you're building? nocash has some info on those cartridges and their data layout. Maybe that can be of help to you.

Could you elaborate a bit more on what you mean by "SF-memory"? Do you mean SD memory card? Or are you talking about the SNES's own RAM?

Some of the things in there reminded me of Giana Sisters. It looks and sounds great so far.

And of course amazon won't allow me to buy or rent it digitally as a swedish customer.. *sad trombone*

After the 2007 Tour de France stage race, I noticed that the winner's average speed was only 1mph faster than that of the 1962 TdF, and the '62 one had longer stages and still some unpaved roads. IOW, the '62 winner might otherwise have been faster than the '07 winner in spite of the technology adv...

I have a feeling that it's not synchronizing the DAC value generation and the NGPC audio playback, and is instead cycle timing things perfectly. If that's the case, then being off at all would result in the two desyncing and the CPU code overwriting DAC samples before they are played. My YM emulati...

or the second SH-2 in the Sega Saturn?

The second SH-2 in the Saturn/32X didn't have any specific purpose. It's identical to the main CPU.

I can whine at him to check the repository I was saying that he's been pretty quick to respond in my experience, if BMBx64's concern was that he's completely abadoned dragonlib, so no need for nagging :wink: These routines look like they could be useful to others, and I think it's far superior to h...

I could try, but most of his files are 5 years old on github though.

I think Shaun will respond if you do a pull request on github. I made one 9 months ago and IIRC he got back to me within a couple of days.

Cool. You should think about doing a pull request to get your routines merged into libdragon (if you haven't already done so).
