gba VS Mimic

Are you aware of https://github.com/rust-console/gba ?

Yeah, there's actually a library crate with quite a few examples that I used: https://github.com/rust-console/gba

Not open-source console, but there is GBA from scratch book. There is also an gba crate that makes programming on GBA easier.

There is a rust port for the game boy advance https://github.com/rust-console/gba

GBA: ARM7TDMI, supported by upstream LLVM and GCC, some Rust support

Sure, https://github.com/jawline/Mimic

Thanks! The code is available: https://github.com/jawline/Mimic/blob/master/src/terminal.rs here. I use a library called Drawille to render the screen into an alternate mode terminal.

I think the core issue here is mainly that a giant match isn't the best way to express opcode tables, and jump tables are just a bit more idiomatic here as in other languages. I've also been working on an emulator for the gameboy in Rust (https://github.com/jawline/Mimic, I wanted to be able to draw gameboy games to the command line) and I think the use of a jump table made it a bunch simpler / easier to refactor (https://github.com/jawline/Mimic/blob/9463b658ebf006b2369d2b...).

I've been playing around with making my own GB emulator. When I run Super Mario Land the game runs but the first few and last rows of the text at the top seem to render with scx as the character but the inner text renders correctly. Could anybody give me some hints as to what's going wrong? (source: https://github.com/jawline/Mimic)
