CV Wonder first of all, welcome to the forums!
Then, you’re right, while it was certainly not designed as an upsell (two tools designed independently, one after another) it currently certainly seems like an upsell! :-)
We really like to open up zetaSID to the community, to experiment with and listen to it, even to users not owning the hardware, so i hope you believe me when i say that this was not intentional.
Let me think about this for a while if and how we can integrate the two - they are two completely different technologies, one is an optimized encapsulated web assembly based emulator (which cannot emulate the SD card as the hardware is not present), the other is a web toolkit used to control the real hardware. Hmm………
Best regards,
Peter
