I have no sympathy for the development of such products. First they treat emu systems as a free disposable software pool to bootstrap their business (see Retron 5 abuse of difference software licenses). To some extent I would even say they also exploit the translation communities (ips support promoted by Retron 5) yet without any mechanism to link back to such communities or the patch author(s). Second they flood the gaming market with tricked players who are buying games thinking they're playing the real deal, whereas in fact, they are merely playing a ROM dump on an emu, not even a cheap SoC clone. It is a manipulative ersatz, not so different from the artificial shutter sound added to digital cameras to reinforce the illusion that this is still a working mechanical device.
