First of all thanks for the developers who made a great distribution.
I actually have a problem with naomi vertical shoot them up ratio. I like to play Illvelo and Ikaruga.
After set the screen to vertical in retroarch and create a configuration file with the rom i see that the ratio isn't good. The game is fullscreen and i would prefer have black bands. In fact you can have it if you go in the retroarch menu then settings > video and set the custom aspect ratio width to 716 instead of 1196.
But the configuration doesn't stay if i quit the game and relaunch it.
Off course i like to play other games un horizontal mode. I would like to use a custom config file for games in vertical mode if it's possible.
Someone succed to resolve this ?
