I am not sure if this is the right place and I know I probably have not put in enough info but I do not have much knowledge
I have an arcade set up using a pc and hyperspin which I kinda understand and last week got a pi 3. I moved over the snes, master system xxxxxx spectrum and mega drive games over (only have the ones I own!!)
I also have 7 mame roms which work great in hyperspin.
After transferring them the snes mega drive and master systems work perfectly in emulationstation (got the latest retro pie image) but the 7 mame games and the spectrum ones do not work
When you click on them the screen goes black with a little white flicker in top left then goes back to game selection screen.
I have put in a neogeo.zip file as that seemed to be a popular fix on google but still same issue
I am sure it is something so simple I will kick myself but my Linux knowledge is zero so poking about is not much of an option for me lol
