C64 Hardware Simulator Isn’t (Just) For Playing Around
If you want to play old Commodore games, there are C-64 emulators available for just about any platform– but most of them are so high level, they’re really meant for just that: playing games.
Executive Summary
If you want to play old Commodore games, there are C-64 emulators available for just about any platform– but most of them are so high level, they’re really meant for just that: playing games. [antirez] has a different goal with his c64-hw-sim project — it’s a lower-level emulation that simulates every chip and every connection on an ASSY 250407 motherboard, and all the chips on it, too.
Open Silicon & Gate-Level Hardware Inspection
From a silicon and hardware engineering viewpoint: - **Interface Neutrality:** Mitigates dependency on proprietary BSPs, empowering open toolchains to address hardware directly. - **Supply Chain Verification:** Schematics and open pinouts allow deterministic audits against silicon errata. - **Lifecycle Decoupling:** Decouples physical hardware utility from commercial vendor end-of-life obsolescence.
Impact on the Open Ecosystem
Ensures that computational autonomy remains in the hands of the architect rather than closed silicon vendors.
