Nobody is clamoring for that, to be honest. Listen, mail me, and I'll try to explain why this is a no-go. However, it's perfectly possible if you know some 6502.

It makes no sense to modify a SID. The environment is the sidplayer, webplayer, the C64 itself. A sid is not self-contained, it's just a setup and a "play" vector. The rest has to be set up by you (aka the environment). We go in circles here. You're welcome to email me at dmx at rebelandroid.com

It just lacks the good ol'e "tingle" is all. :)

Good idea, but tbh I'd just make a new init/play below the original start address. The old game SIDs are all over the place in memory, naturally, but most of the new ones are at $1000 as standard.

What I mean is, there is no universal way of converting every possible sid automatically. There's often some manual labour needed.

Sorry, bsky makes it difficult to find the context here, but 99% of sids got a player built in. But as an example: Ocean Loader 3 is a CIA player. Due to the "environment" the SID spec expects, all for the player to do is to set the CIA tempo, it doesn't "set up" the full environment itself.

It is nice indeed :-) Seriously, any coder can take a SID and make it play at the correct speed in their NTSC production. Problem for "general solution" is that a game or demo may prefer their own way of setting up their env, which may not exactly be as the expected env for a SID = manual tinkering.

I understand. I just don't see what's stopping any NTSC coder taking any SID and playing it at the correct speed in their NTSC compatible demo or game. There is no magic bullet, I think there has to be some labour involved.

Yes, it could work for a majority of SIDs. But I just fail to recognize the use for this? I mean, I assume they play fine in the correct speed on NTSC PCs, even using something like PSID64 on an NTSC C64. Just trying to understand why this is needed. :)

Ah okay, then I've misunderstood, that is an order/magnitude greater task, and I won't be able to help out on that one, unfortunately.

He he... I'm in my little nerd bubble, I guess. Anyway, been working on the player, very soon ready for testing. Stay tuned!

Hi. You set register A to the subtune, then JSR init. After that, JSR play every frame. 99% of multi-song SIDs contain the player code, then some pointers to the different sub-arrangements. Almost all share instruments, in many cases even the patterns / sequences. But it's also different :)

Yeah I'm a bit late on that. But there's some progress, got the player good enough for a first go, need to support selecting subtunes. The hvsc db is up on my site, now I need to create some interface to actually generate the prg from that (using an assembler in the background.) Stay tuned :-)

Couldn't find any music from this, did the allmighty Paul not make the music for this? Shocked

Love that old Symphony of Science song feat. Sagan. Btw. try this tool sourceforge.net/projects/sid... - it'll play SIDs correctly on NTSC, according to it's readme.

Started working on it, hope to have something over the weekend. Cheers

I'm hoping to whip up a proof of concept well in time for Halloween. I have a good idea what to do.
