Hi everyone. a newbie here just wanted to say thanks for everyone's contribution that help and support Attract Mode. Who ever knew that a frontend could add so much to the experience. After using AM, I can't ever go back. lol. Sadly that is why im here... I finally got everything running EXCEPT MAME. Im using RaspberryPi 3 with MAME4ALL and it looks like its going to start then goes blank with the glGetError 0x500. I looked everywhere for a WEEK now, and found only config info for everything else like mame on windows, linux, or just advMame and mame2003. the funny thing is im just lacking 2 lines of code; 1) the executable path: and 2) the argument path: . I actually surprised with all of the issues people are having getting mame to work, there isn't a section that shows each, (for each OS). this problem seems so simple that i tried to find the mame config file from ES and copy it to AM, but clearly that didnt work. I hope there is someone out there that could point me in the right direction:( and although i found other glGetError 0x500 issues, i hope that is the only reason its not working. thanks again
