PC-FX (android retro arch) Partially working and Black Screen!

sorry for posting again. but i can’t wait T_T

I have bin file and cue file of Dokusei 2 and Pia carrot.

I run the Dokusei 2 first. (right directory right bios, I think)

I saw the animatoin mark (PC-FX mark) but game(Dokusei2) was not working.

I change the setting (video setting-> Threaded Video Off)

And then I could see the mark of Dokusei 2 and hear Background music of the beginning theme[B].

However, after that signal, there was[B] blackscreen.

other game (pia carrot) is also[B] blackscreen after i wrote my name in the game.

What should I do???

ps : my device is Samsung Galaxy S4mini and android 4.4.4[/B][/B][/B]

[SIZE=3] There’s something wrong retroarch applicatoin.

I run perfectly the game with “mednafen” and “MedGui Reborn v0.056 Beta full”

I just wait for new version of retroarch to play in my phone. [/SIZE]
