@CypherDAO: working Commodore 64 emulator running on Ethereum

A working Commodore 64 emulator has run on Ethereum mainnet since 2022, according to a thread by @CypherDAO. The thread says the machine boots on demand, executes programs and generates sound live, and is not limited to a single program. It describes the C64 as open on-chain infrastructure that anyone can access, study and build with.
