I remember trying to install Dingux for the first time my friend. I had a really difficult time due to the root & z image files that had to be copied to the Dingoo off of Windows. It really is just a matter of copying the root & z image files in the proper order to the Dingoo. Once those are in the proper order & pasted through windows explorer, Dingux should start up automatically on its own.
Then I had a really difficult time getting the emulators up & running, then attaching the games to the emulator as a link, etc. Dingux is definitely tricky trying to get installed also due to the Micro sd card needed. If you have any questions, feel free to ask. I will respond very quickly. Hope you get everything installed okay. See ya!
