RP2350Sharp
RP2350Sharp is a cycle-accurate emulator for the Raspberry Pi RP2350 (Raspberry Pi Pico 2) microcontroller, written entirely in modern C# (.NET 10). It models the dual-architecture core — Arm Cortex-M33 and the Hazard3 RISC-V cores — along with the BusInterconnect and peripherals, and runs real RP2350 firmware (including MicroPython) without modification.
It is the RP2350 sibling of RP2040Sharp, sharing its design lineage from the excellent rp2040js project by Uri Shaked.
