Question 1

How do I run classic games like Space Invaders with i8080?

Accepted Answer

i8080 only emulates the Intel 8080 CPU, so you need to integrate it with emulations of other hardware (e.g., memory, I/O ports). The separate Space Invaders repository shows a complete setup, but it requires additional development effort.

Question 2

Is i8080 more accurate than emulators written in C?

Accepted Answer

i8080 emphasizes accuracy through validated test ROMs, as seen in the README, but direct performance or accuracy comparisons depend on implementation specifics. Rust's safety features may reduce bugs, but no benchmarks are provided.

Question 3

Can i8080 emulate Z80 CPUs or other processors?

Accepted Answer

No, i8080 is specifically designed for the Intel 8080 CPU. The Z80 has extended instructions and hardware, so it's not compatible without significant modifications or a different emulator.

Question 4

What's needed to test i8080's accuracy?

Accepted Answer

Use the included test ROMs by running the Python script to download them and executing the cargo command for test_roms, as detailed in the README. This verifies CPU behavior against standard diagnostics.

Question 5

How to integrate i8080 into a Rust project for custom emulation?

Accepted Answer

Add i8080 as a Git dependency in Cargo.toml, then instantiate the CPU and implement memory and I/O interfaces based on your target system. The README provides minimal examples, so familiarity with 8080 architecture is essential.

Question 6

i8080 or other emulators for educational projects on CPU architecture?

Accepted Answer

i8080 is strong for focused Intel 8080 study due to its verified accuracy and Rust code, but it lacks built-in educational tools. Broader emulators might offer more features, but i8080's simplicity can aid in understanding low-level emulation.
