MAME on PPSSPP please help

[Dazman]

Please can anyone help me to get MAME to run on my Windows 10 PPSSPP setup.

I have a PSP and use MAME4ALL V4.9R2 USERMODE (Works Great)

I have lots of other emulators C64,LYNX,SNES etc. and they all work on PPSSPP. MAME if the only one left to get to work.

When i open MAME i just get a black screen.

I have tried every PSP version of mame and they all do the same.

I have also tried early builds of PPSSPP and one versio did load PSP MAME to the menu but died when you select run a game.

I have tried changing many settings and had no joy yet it does say it works in the spread sheet.
