So what's the difference between the paid and free versions of the emulators? Additionally where can I get ROMs?
The Paid allows you to Save and Load states of the game. Needed for games that don't allow you to save in the game. The Lite will play just the same, but you can't save your game and load it back up unless it is saved in the game.
That's odd? I was able to save Pokemon on Gameboid lite when I played it? If anything I would say just buy them. They are really cheap and a lot of fun to have on your phone.
probably not... Usually when you save a game "in-game" it creates a small file usually with a .sav on the end and stores it either in a specified "SAVE" folder or just in the emulators folder somewere.
I dont know much about the individual features that you gain by paying, but you should pay for it either way, it takes time and effort to prefect these emulators, and by buying yo can garuntee you'll get any updates when they come out, idk if he releases them for paid before free.
