Dynamically add/change files on disk?

[Sgeo]

I would love to use VC64Web to make it easy to listen to CGSC music, especially stereo music which doesn't work on DeepSid and wds (which DeepSID supports but doesn't scroll).

I'm thinking that I would take a copy of StereoPlayer 10.5, and add the music files to the emulated disk. But I'm not sure how or if I can do that part (other than synthesizing a d64). Is there a mode where a "disk" is just separate in memory files?

I have peeked into the Core API and it looks like this file has the methods for that

https://github.com/vc64web/virtualc64web/blob/master/Emulator/FileSystems/FileSystem.cpp

I have to expose them to javascript and then it should be possible to write files to an disk I think ... we can ask @dirkwhoffmann (creator of the virtualC64 Core) what he thinks

But I spotted another problem... I tried this

https://csdb.dk/release/?id=101655

and the player itself loads and runs fine... until ... I select a song and start to play that...

then it seems as if the read logic gets wrong data ... sometimes wrong notes and often it does not play notes at all and it is muted... the songs text has also often errors

see here

text is ok but sound is wrong .. too slow and wrong notes

now F5 Abort and second try

and here

it shows no song text at all ... only the petscii and the pound char. Also no sound is played this time.

I will open an issue in the original repo about that.

Just to check, are you using NTSC? These programs don't work well on PAL, the Compute Gazette SidPlayer music scene, as such, was mostly (entirely?) in ... the Americas I guess? It was popular on Q-Link which was in the US and Canada

You are right 😎 🙏… with an NTSC vicII 8562 … it works without a flaw

I managed meanwhile to configure 2nd SID to $d500 in StereoPlayer 10.5. and also I set the mode to Stereo

But when I interprete the V L R display correctly

Then it plays nothing on channel R ? Only in the L column the notes come and go …

Am I still missing something ? I did choose the „Human league - STEREO“

(On vc64web side I did set 2nd SID to $d500 and audio output to stereo)

Set mode to NORMAL and turn Fast Load OFF:
I believe Stereo mode is for sending mono files to both SID chips instead of one.
Fast load works poorly if the 1541 isn't emulated very exactly.

The StereoPlayer 10.3 disk in https://www.c64music.co.uk/ CGSC_Commodore64 has documentation from that era
