A couple of moths ago, I grabbed a (real) Dingoo A-380 and gave CFW 2.11.09 a try. First, I'd like to thank the authors and contributors of the firmware and emulators, who made a very capable handheld out of the A-380.
So far, I've run into a few (non show-stopping) issues which I thought to report, also to the benfit of other users.
1) I cannot boot the factory kernel: I've installed the emu pack (and the vmlinux folder) in the required locations; when I launch dingux from the settings > vmlinux menu, the Dingoo reboots but doesn't load dmenu (it stays on an empty screen with the "paw" backgound) and I have to reset it to bring it back (thus returning to the custom kernel, I guess?). I've read of a similar issue with a previous CFW version in this very thread, so maybe it's a known problem. I've yet to try under the old CFW 2.11.04, which I see is still available for download in the OP (I'm not too keen on opening my A-380 again, but I'll do it if necessary).
2) So far, I've only tested the CFW Final Burn Alpha emu and it's great. I've noticed that the emu creates a .fba directory inside the /game/fba folder on the internal memory card (where game ROMs are put); that directory contains a 'configs' subdir where the emu saves per-game settings upon exit. The config files are UNIX text files similar to those used by fbacapex frontend in the OD release of the same emu. I've tried editing a couple of these files with Notepad++ (e.g. to select the MAME Z80 core and have correct sound in the Aero Fighters Neo Geo games), but the emu seems to load the games with the default settings nevertheless. I suspect the configs are meant to be used with fbacapex (not ported to A-380), maybe I'm wrong.
3) I have two F-16 wireless controllers that work (one at a time) with my Dingoo A-330. I've unsuccessfully tried to pair both (individually and simultaneously) with the A-380, following the directions I found in two old threads of this forum section. It could well be my unit's fault, since it's used and has clearly been opened before. All I know is that when I turn on wireless controller in settings, the wireless icon appears next to the clock as expected; I then double tap the wireless button on the controller(s) but the red led on it goes on flashing (instead of going out) and the Dingoo obviously doesn't respond to inputs.
I apologize for the lenghty post and would like to thank again all devs involved in this for their excellent work.
