OK, so I waited before commenting on that other 'port' until it had actually been released.
And just like I suspected, it's once again all about 'making money' with the 'donate version' (2.99 Euros here). Yes, I know there is a 'free' public download on xda-developers - doesn't matter - the masses don't even know nor care that an 'apk' is available somewhere on some obscure site since most phones/tablets are unrooted and they can only install stuff from the App Store - so where do you think they will be getting this from? That's right, you'll have to pay the emu porter to be able to use the emu port - ie. the 'donation'.
And again, the source is not really made available to the public in any useful way - he says libafba is licensed under the GPL, but no link on where to get his 'source' (not that I really need it - FBA already runs here on RetroArch Android - but still, it is my RIGHT provided by the GPL that I can look at any derivative sourcecode).
libafba, like FBA, is released under the GNU GPLv2 licence: http://www.gnu.org/licenses/gpl-2.0-standalone.html
(Actually, I'm not sure if FBA is licensed under the GPL 2. Perhaps somebody from the FBA dev team can make that clear).
His previous library version of gngeo also didn't have the source put up somewhere at a publicly available site - you had to personally e-mail him in order to get the source. I mean this is just bullshit - nobody should have to PM anybody in order to get the source - this should be publicly made available and it's the developer/porter's responsibility to put up your sources, no questions asked.
And sorry but I'm going to put my foot down on this sh** - just to make it clear what RetroArch and libretro will NOT be about - and the second reason why it's going to be on Android beyond being merely about 'playing games' - it's also about changing the business landscape there - and more importantly, 'killing it off'.
RetroArch and its ports is NOT about making money - RetroArch will be for free, on any console, on any tablet, on any phone, whatever. Anybody who will ever pay money for any libretro port or any RetroArch port - know that you have been scammed and that you should demand your money back from whomever ripped you off.
This is why it's important that RetroArch makes its appearance on these 'App Stores' for free - to totally kill off this 'make a quick buck by making emulator ports' business. No, you shouldnt feel 'entitled' to making money just because you can port an open source emu - no, putting up a 2.99 Euros version without ads is not really a 'donate version', no, just because the GPL makes it 'possible' for you to do this shouldn't mean that you should do it.
These 'App Stores' and this whole new way of 'making homebrew/doing business' is f***ing up the original spirit of homebrew and open-source. You can call me crazy now, but a few years from now and when everything will have a price tag associated to it and nobody will have the inclination to release any source anymore you will know that I was right. Everybody championing this sh** on happening on the Android App Store/Apple Store is a pallbearer who never gave a damn about open source and free software in the first place.
f*** this entire 'monetizing your apps/port' sh**.
