Rust64 vs ViceSharp
Both stand on commodore 64 emulators. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan
Rust64 offers a code-focused C64 emulator with detailed register and cycle views. Its missing serial bus, timing limitations, build requirements, and work-in-progress status should guide expectations.

ViceSharp offers C64 emulation through desktop, console, and library interfaces, with media capture and a debugger. Users need separate ROMs, and the listed machine support does not yet include C128, PET, or Plus/4.
