First off thanks go out to Paul Slocum for creating Cynthcart and Mario Ballano for creating emudore.
Starting with firmware version v0.8.0 firmwares ending with cc can run Cynthcart.
For example usbsidpico-v1.0_sp_cc.uf2 or usbsidpico2-rgb-v1.3_sp_cc.uf2
Cynthcart runs through the embedded USBSID-Player, so all Cynthcart firmwares _also come with the onboard USBSID-Player included. See the USBSID-Player-manual file for more information.
WARNING! Because Cynthcart runs through the embedded USBSID-Player, the Pico MCU is overclocked to 250MHz, regardless of Pico type (rp2040 or rp2350). Passive cooling might/could be needed.
To start the emulator and Cynthcart you will need an USB-midi connection to USBSID=Pico.
85 (0x55) ~ Enable Cynthcart
86 (0x56) ~ Disable Cynthcart
87 (0x57) ~ Reset Cynthcart (not implemented yet, currently a no-op)
For all other midi CC messages to control Cynthcart please refer to the Cynthcart manual.
