What is evidently clear though is that they are already in violation of the GPL license that we covered this RetroArch code under. If you want photographic evidence, I refer you to the second link I posted below.Īll of the other C code of RetroArch seems to have been obfuscated so it will take us some more time to identify these parts. The relevant parts are the ARM NEON-optimized sinc resampler code and the audio integer to float conversion routines. Now the reason we could identify these snippets is because it is inlined Assembly code that is hard to obfuscate. We found obvious bits of RetroArch’s sourcecode inside their frontend. Proof is in the accompanied screenshots (see below).ĥ.

The screenshots showing the code flow of operation will illustrate this clearest. As for the rest of the code, it is undoubtedly VBA. The game ID strings that are used to identify the ROMs appeared in Retron’s GBA module as well. I (Squarepusher) made this version specifically and I could recognize it was this version because of the fact that I have built-in a game database into this emulator. VBA Next is a derivative of another emulator called VBA-M. It uses the open-source emulator ‘VBA Next’ for its GBA module. Proof of it being FCEUmm is in the accompanied screenshots (see below).Ĥ. Unfortunately, this turns out not to be the case as we’ll find later on – since they are using GPLv3 code inside their frontend as well which is technically incompatible with this license.

Technically they would have been allowed to sell this IF they had made sure their frontend was compatible with GPLv2. It uses the open-source emulator ‘FCEUmm’ for its NES module, which is itself a derivative of FCE Ultra. Proof is in the accompanied screenshots (see below). Libretro is the development interface of RetroArch if you remember. What also bears pointing out is that SNES9x Next has never been released in any other version than the libretro version.

Like Genesis Plus GX, it can therefore not be a part of a commercial product. SNES9x is licensed under a non-commercial license. We could tell it was the SNES9x Next core because the exact same strings for variables to do with the speed hacks and the SuperFX overclock code popped up in their SNES core. This comes at the expense of some graphics inaccuracies though. It has SuperFX overclocking code and it has certain game speed hacks that make games run faster on slower hardware. It has a few differences compared to normal SNES9x. I (Squarepusher) personally made this version of SNES9x. It uses the open-source emulator ‘SNES9x Next’, which is itself a derivative of SNES9x ( ). None of the authors were contacted about their code’s use in the Retron5 hardware.Ģ. Proof is in the accompanied screenshots at the bottom of this post. It can therefore not be sold as, or part of, a commercial product. This core has been licensed under a non-commercial license. It uses the open-source emulator ‘Genesis Plus GX’ by author Eke-Eke for its Sega Genesis/Mega Drive module ( ).

We have discovered that Retron5 is in violation of the licenses of several projects:ġ. Several of the emulators are covered under non-commercial licenses, which means they cannot be sold or profited from. These open-source programs are covered under certain licenses.

We are on over 15 different hardware platforms right now that you can run RetroArch on, including Android (which this Retron5 device is based on). We started this project in late 2010 and we have been steadily increasing in popularity. This development interface is open to others so that they can run these pluggable emulator and game cores also in their own programs or devices. It has a development interface called libretro that allows for the easy creation of emulators and games that can plug straight into this program called RetroArch. We have an open-source project called RetroArch.
