Deca

Deca is basically just another CHIP-8 emulator written in Rust, but it

• is a backend library with no I/O, which can be embedded into a UI (like Termin-8, which runs in a terminal).
• has full CHIP-8, SUPER-CHIP and XO-CHIP support (multiple colors!)
• aims to behave as closely to Octo/C-Octo as possible

Future plans

• Support for various CHIP-8 extensions and variations, so it can run as many historical CHIP-8 programs as possible
• Other crates that can compile Octo programs (decasm) and read/write Octocarts (decart), inspired by the components of C-Octo (possibly even an IDE (decade) inspired by Octode??)

Why "Deca"?

Deca is inspired by (heavily based on) Octo, which has an octopus as a mascot (as a reference to CHIP-8). Octopi are eight-limbed molluscs belonging to the order Octopoda. Deca is written in Rust, which has a crab as its mascot. Crabs are ten-limbed crustaceans of the order Decapoda.

To further justify the silly name, I plan to add support for CHIP-10 as well.
