i use mame (selfcompiled) 0.186 in kubuntu 17.04 64bit.
today i tried to play around with screenshooting using the mame buildin frontend.
what i tried was to randomly take screenshots from a game, let's take 1942 as example.
started the game and randomly pressed f12 ingame. the result is a subdirectory 1942 in snap
with files numbered 0000.png 0001.png and so on. so all is fine.
then i tried to do the very same with a softlist. let's take atari 7800 softlist and commando as example.
started the game via the buildin frontend. pressed f12 randomly.
the result is a subirectory a7800 containing exactly 1 screenshot named commando.png.
so when doing screens from a softlist i take always 1 screenshot which gets overwritten once i do another.
is this intended or a bug or did i configure something wrong in my mame.ini ?
i think this is the relevant part of my mame.ini
