Thought you might like to know about a work-in-progress EBOOT loader for v2.0 firmware, that improves on the existing v0.1 loader.
This now works with a much larger range of homebrew than the previous loader, and includes diagnostic information if it has problems loading a particular EBOOT.
The main limitation is that it does NOT support kernel-mode applications.
I'd be very interested to hear from people with their test results - both for interesting homebrew that does now work, and also for any EBOOTs that still aren't working.
You can download it here.
The readme file inside the ZIP contains installation instructions.
