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).

Looking good. Do you know why you're getting those sprite columns that fill the entire screen? Seems to only happen for some sprites.. Perhaps related to the sprite size?

That looks like what I'd expect. Though I haven't made any hardware tests to verify this, so I was curious about that NOT and whether it was based on some recent discovery. If it wasn't then I'd say leave it out for the time being.

Why is there a bitwise NOT in there? All descriptions of the SN76489 noise channel I've seen have had the new bit15 set to bit0 XOR bit3 in "white noise" mode. Has someone made recordings where they concluded that it should in fact be bit0 XOR (NOT bit3) ?

And the cardboard box inside had both the sender's name and address as well as mine written on it. Ah. Well, that certainly is suspicious. If they were stolen, that seems like a pretty stupid move by the thief(s). How do you liquidate 100 PAL SNES carts in NTSC land quickly without garnering attent...

Wait.. $5000+ worth of games weighing close to 20 lbs were sent across the atlantic just wrapped in some paper? Or was there a cardboard box that the USPS simply couldn't be bothered to deliver? I'm not saying that the USPS still hasn't screwed up, but if what's shown in the photo is all the packagi...
