Rust Journey – Chip8 Emulator – Day Who Knows

This post sums up the small iterations of three different days. Basically, I implemented 9xy0 and cxkk opcodes, fixed some typos, corrected a few inconsistent implementations, and added SFML redraw only when the display opcode(dxyn) was called. Hence improving the performance.

I passed both test_opcode.ch8 and BC_test.ch8 test roms, which made many other roms work as well. I still need to implement the sound, input, and delay opcodes.

It’s been an enjoyable journey so far, besides taking a bit long due to the lack of free time. I am always thrilled when I get my hands on something different that’s not web-development related.
