thanks pcercuei!

i couldn't get this to work on my Win10 machine this morning. the driver installer doesn't appear to do anything when run. something flashes up in the taskbar for a split second but that's it.

anyone had any luck?

if not i will try on a linux machine later.

Yes w10 is bad use linux

cd Desktop
cd flasher
sudo ./flash.sh

Linux instructions above for flashing copy the flasher to your desktop and type the commands then Hold Button A if not B then power on you will then get some commands like below.You then finish the rest of the install on the rs90 device itself enjoy :)

I had luck in win10, but after the installation, sd card cant be seen, even with the files in it.

Additionaly i cannot get access to the system tree to add the emulator.

It shows always half battery, is this ok?

But it boots ok i guess

You need to go into device manager and find the JZ4725 device and right click - update driver. Then point the dialog box at the folder with pcerceui's drivers.

The drivers won't install if you don't have driver signature enforcement disabled:

thanks, i did disable driver signing and tried your suggestion but still got an error installing the driver through device manager. i used a linux PC instead and it worked fine.

SD cards support seems to be broken. Even if it appears in the filesystem the apps and emus will crash when trying to read from it. I'll add a workaround in the kernel, and update the flasher. In the meantime, avoid using external SD cards.

For the half-empty battery icon - it's just that the driver isn't very well calibrated.

Oh... thats bad. How much internal space retromini has with this cfw?

Hope SD support gets solved soon. I have my whole life in there lol!

Guys use the new thread that is in sticky for support for rs90 from now as we can't chat in both to much hassle thanks.

Ahh... I'm stupid  ;D

So they are the same even though it's the same shop. Odd.
