Why blaming them of stealing other peoples software, without actual proof?
Compare Dingoo's GBA and GPSP and you'll see. Same glitches in the same games in the same moments. Coincidence?
No proof. Many different emulators have the same glitches in the same games. Just look at different PC-Engine Emulators for example, many of them have the same glitches, when it comes to emulating "Outrun". Many Dreamcast Emulators have the same glitches, when it comes to displaying the background in "Rez". Many N64 Emulators have the same glitches, when it comes to displaying the characters in "Paper Mario". This isn't a proof. And in fact, I never heard anybody saying, including Exophase, that he has a PROOF, that gpsp code is used in the native FW emulator.
I don't say, that it is prooven, that they don't use gpsp code, but I am a little tired of people accusing somebody of something, they can't proof.
@ gibberish
What you call a frontend is the main reason, why the Dingoo was successful in the first place. Most users, which bought the device use mainly the native Firmware and I must say, this FW is well thought and very stable. If it is so easy, why nobody before Dingoo Digital made such a device? In fact, most open Handheld systems lack of any good packaged player applications and emulators and almost every MP3 Handheld I have seen besides the Dingoo lacks usability, emulator variety, video and audio codec variety and a well thought menu structure. In all these points, the Dingoo sticks out of the masses of all the MP3 players that are on the market.
It is easy to say
"It is common knowledge that the standard emulators that come on the dingoo are 'stolen' open source projects, for which they should have released their source and havent."
But then it should be easy for you to show us all here the proof, cause this should be common knowledge too.
