And there is more evidence than just words that DT is the home of the original creators. Such as DT being able to make new models and upgrades, while DD has done nothing yet, besides be stupid little children who have got to sling dirt around on other people to sell units.
Ahhh, that is your "TON of evidence", ok then...
A question, dingoo is really outdated for you?
That "Great one new upgrade" is really useful? Before aswersing it, remember, that "new RAM improvement" is literally useless, just a piece of chip in the PCB who can't even be used in actual native OS, neither in actual dingux.
And a portable controller in a portable device(yo dawg) is not the best piece of "upgrade" I can imagine, and it CANT be used to make a 2 controller thing/multi-player between dingoos because it's just soldered in the controller circuit.
And the great PSP rip-off design(a.k.a PSP games A330).
SO why a company who CREATED a good handheld, would want to do such dubious "great improvements" in your master-piece?
And you really think 2 really easy-to-do improvement(useless RAM/spare remote control) is the proof who dingoo technology is better?
They can't do any kind of major upgrade other that spare chips pasted on original PCB, because they don't have any kind of know-how to do real improvements, like to change the firmware to accept a real wireless or to accept more real RAM.
Your "upgrade" is just a piece of amadeur-modding to me, real upgrade is more than it.
I really can't get where is your "TON of evidence".
To DDU, you earn money(amount of money is relative, but it's still money), so to me all your "help" is marketing/merchandising to get(directly and indirectly) more customers.
