Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Klaus Dormann's 6502 tests don't rely on a particular emulator environment. They could be used with Ghidra.

How do I tell if my 65c02 is bad?
How about some assembler code to test all of the opcodes? https://github.com/klaus2m5/6502_65c02_functional_tests

I made a cycle accurate profiler for 65C02 assembly with visualizations
https://github.com/Klaus2m5/6502_65C02_functional_tests might be worth a look, it's a comprehensive test suite

What's the address of the monitor disassembly routine?
Great! (and not surprising). You may want to look into using a 6520 test suite to check correctness of your emulator, like this one -- note: I have no experience with it, but it took me some time to iron out the last error of my 6502 emulator, and in hindsight I should probably have used such test suite.

Test - Corner cases for 6502 Instructions.
Currently i'm trying to implement 6502's instructions one by one using TDD. I was curious are there any test - corner cases already been written ? I found out ( https://github.com/Klaus2m5/6502_65C02_functional_tests ) but this requires all instructions to be implemented which I don't currently. Is there any way to test a single instruction in isolation for all the edge cases ?

Apple //e enhanced ROM oddness
By "bad branch", I mean the emulator takes the wrong branch because it fails to emulate some part of the Apple hardware properly. The 65C02 emulation has passed some pretty stringent tests (https://github.com/Klaus2m5/6502_65C02_functional_tests/blob/master/bin_files/65C02_extended_opcodes_test.lst), so I'm pretty confident in it. But the instruction trace file is around 90,000 lines, so is kinda hard to slog through.

Dogbolt Decompiler Explorer
Binary Ninja likewise is empty and keeps up just fine as well. It's not a coincidence that the two commercial products that are funding it are both confident enough to put their stuff online like this.
And it's no conspiracy theory or intentional sandbagging, you can see the implementation: https://github.com/decompiler-explorer/decompiler-explorer
and if anyone can improve the other tools performance we'd be happy to accept it. We reached out to the Ghidra devs: https://github.com/NationalSecurityAgency/ghidra/issues/5228 but they didn't have any silver bullets for us either.

Nice, I'll give it a closer look. My only concern so far is memory hooking (still needed for hardware registers), which on Java side was called by FilteredMemoryState [1]. In memstate.cc it looks like just the simpler MemoryState is implemented [2], and there's no equivalent to MemoryAccessFilter. But it might not be that complicated to add...
