Cannot compile Loader

[DLDrago]

I'm having problems compiling the SNES Loader. It says it can't find or load the main class. (org.gradle.wrapper.GradleWrapperMain"

Oops, I missing checking in the Gradle .jar file. Update and try again.

In the current state I believe master will build for Ghidra version 9.0.4 and earlier, but not version 9.1.x
Pull request #1 updates the code for version 9.1.2 -- you should be able to apply that branch on top of master (delete the .classpath and .project files when they conflict).

Never mind that, I've accepted that pull request now. It should just build now, but let me know if it's still no good.

Now I get this error:

What version of Ghidra are you using?

[DLDrago]

9.1.2

Are you doing the plain command-line build, or trying to use Eclipse?
If I do a clean checkout and do a plain command-line build with Ghidra 9.1.2 on Linux it just works.

[DLDrago]

I've tried both the Powershell and Command Prompt on Windows 10.

Based on this I wonder if the build is using the wrong version of Java. The Ghidra installation guide says it requires Java 11.

If you run gradlew.bat -v it will tell you which version of the JVM it is using. I'd imagine that any 11.x is ok (mine says 11.0.9).

[DLDrago]

I can't compile it. Do you mind making a release file?

[achan1989]

I'll give it a go; tomorrow or over the weekend.

[DLDrago]

Ok, thanks.

I got it to compile by leaving the quotes off the Ghidra directory. Now Ghidra says it supports SNES ROMs, but every one I open only seems to allow Raw Binary. Is there something I'm doing wrong?

[achan1989]

It's a two part setup.

First, make sure the SNES loader extension is installed. Once you've built it, there should be a file in the SnesLoader/dist directory. Copy the ghidra_9.1.2_PUBLIC_20201029_SnesLoader.zip file into <ghidra-install-dir>/Extensions/Ghidra, then run Ghidra and activate the extension via File --> Install Extensions...

Second, you also need to install the 65816 processor module. Code and installations instructions are in https://github.com/achan1989/ghidra-65816

Then restart Ghidra. If everything is set up ok, you should see "SNES ROM" as an available format when you try to import a ROM. Then set the language (65816 should be the only option) and you should be good to go.

I'll warn you that these tools are not polished, and will probably not do what you want them to out of the box. The processor module is kinda ok, but has problems with switching processor modes automatically. The loader is hard coded for one specific ROM format (possibly for one specific game), and I can't remember if that's even correct and complete. Be prepared to change the loader code.

Ok, thank you.
