I have the Miyoo Mini+. I originally used MinUI and it saved games like a normal GBA and loaded the game to the menu everytime I started it, again like a standard GBA worked. I switched to OnionOS to have a nicer interface with boxart and now it only uses save states and auto starts from said state when opening a game. Not an authentic experience.
I have learned there’s a difference between game saves and save states but don’t know how to switch my handheld to use only game saves. Is it based on the core used maybe? Can anyone help me out?
Also, though rarer nowadays, some older games had bonuses if you had the game saves, the sole save format back then, of others (usually previous) games from the franchise. Naruto Ultimate Ninja 5 and Dragon Ball Budokai Tenkaichi 2, for example and if memory doesn’t fail me, gave you money if they detected saves from, respectively, Ultimate Ninja 4 and Budokai Tenkaichi, while Persona 3 FES allows you to carry over the compendium of Persona 3 saves and Final Fantasy X can bring over from other saves of the same game items needed to understand the language of a group in the story.
