I would say yes, but I'm biased as I made the Dingoonity 1.2a/1.2b
Speaking of which, did you ever release a version based on the official 1.22 firmware? And if not, was it because of lack of time/interest, or because none of the changes 1.20 -> 1.22 were relevant to your custom firmware?
I never did release a 1.22-based firmware, because of a couple of reasons - lack of time/interest is one of them, moving away from using Windows is another reason. There are little/no tools for manipulating HXF files on Mac OS, and I don't have the time to set up a Windows virtual machine just to run these tools.
Can someone give me the PSP theme ??Is THERE a better emulator for gba with better graphics ?
