[core] GDB improvements (#3848) 
The commands to reproduce the issues are in the commit messages. I tested on Super Mario Odyssey using [nx2elf](https://github.com/shuffle2/nx2elf) converted binaries and gdb-multiarch:

Eden
Eden

Eden is a free and opensource (FOSS) Switch 1 emulator, derived from Yuzu and Sudachi - started by developer Camille LaVey. It's written in C++ with portability in mind, with builds for Windows, Linux, macOS, Android, FreeBSD and more.

Compatibility

The emulator is capable of running most commercial games at full speed, provided you meet the necessary hardware requirements.

A list of supported games will be available in future. Please be patient.

Check out our website for the latest news on exciting features, monthly progress reports, and more!

Packaging status

Development

Most of the development happens on our Git server. It is also where our central repository is hosted. For development discussions, please join us on Discord or Stoat. You can also follow us on X (Twitter) for updates and announcements.

If you would like to contribute, we are open to new developers and pull requests. Please ensure that your work is of a high standard and properly documented. You can also contact any of the developers on Discord or Stoat to learn more about the current state of the emulator.

See the sign-up instructions for information on registration.

Alternatively, if you wish to add translations, go to the Eden project on Transifex and review the translations README.

Documentation

We have a user manual! See our User Handbook.

Building

See the General Build Guide

For information on provided development tooling, see the Tools directory

Download

You can download the latest releases from here.

Save us some bandwidth! We have mirrors available as well.

Support

If you enjoy the project and would like to support us financially, please check out our developers' donation pages!

Any donations received will go towards things such as:

  • Switch consoles to explore and reverse-engineer the hardware
  • Switch games for testing, reverse-engineering, and implementing new features
  • Web hosting and infrastructure setup
  • Additional hardware (e.g. GPUs as needed to improve rendering support, other peripherals to add support for, etc.)
  • CI Infrastructure

If you would prefer to support us in a different way, please join our Discord and talk to Camille or any of our other developers.
