I've built your extension from master branch (commit 416a6d2) and installed the extension to GHidra 9.1.2.

When attempting to import a WASM file for decompilation, I get following error:

Error importing file: alp_wasm_bg.wasm

Did I do something wrong?

Hello!

I'm building a fork of this loader that is currently able to disassemble .wasm files and hopefully will soon be able to decompile them as well. The current work is available at https://github.com/garrettgu10/ghidra_wasm.

I just have two quick questions for the owner of this repo:

1. When the functionality is complete, is the owner amenable to accepting a PR into this repository?
2. When the functionality is complete, is the owner okay with me trying to get it merged into mainline Ghidra (with credit to the owner for the loader of course)?

Thanks!

Hi,
can this project be run with Ghidra 9.0.4?

I have this error and it seems to not work.
