Saturn Ghidra Sega Saturn Loader

[VGKintsugi]

I uploaded my Sega Saturn loader for Ghidra: https://github.com/VGKintsugi/Ghidra-SegaSaturn-Loader.

It currently only supports ISO files. It will load the Sega Saturn header, security check, initial program (the code that runs during the Sega logo), and the first executable file on the disc. I plan on adding Yabause Save State support next.

Let me know what you guys think.

Wow, this sounds really helpful. I'll download and give some feedback. Would be great for translation projects!

I added Yabause save state support and cleaned up the code a bit. I plan on adding Mednafen save support next .

Please let me know if there's a feature that would assist with translation projects.

Well I noticed (on the screenshot I guess?) that pointers were undefined types. Is this the case? If so, can we change them by tracking the usage from instructions?

Take a look at the PS1 loader to see how powerful Ghidra can be: https://www.obscuregamers.com/threads/playstation-re-toolchain-for-ghidra.895/#post-5792 I've got a lot to learn so it will take some time.

Regarding your pointers question, yes you can redefine types\structures easily in Ghidra. The screenshot I have is without any manually RE, just what Ghidra spits out by default.

I cut a new release that:

• Adds support for Mednafen save states. Must be gunzip-ed first.
• Adds labels for Master\Slave SH-2 PC, PR, and R15

Let me know if there's any other features you guys would find useful.
