Gaming How to play 'Arcade Archive' games?

[tjok3000]

I installed some Neo Geo ACA 'arcade archive' games. But when running, it gives a popup saying I need another thing. And it won't run.
What is the thing it needs? How can I get it to run?
Many thanks!

It's like this, I allready installed it and it is clickable on the home screen. But then it says: You must have the software in order to play
And I can choose Cancel or eShop

Maybe you only installed the update?

Aah you are right! I installed some games, only the updates. I was thinking there was some Master Arcade setup or something!
It works now, thanks!
