No, it is NOT worth buying to support the devs. Emulators have been FREE for at least a decade on the PC.Yet now just because the emulator is on a phone people should pay for the same stuff?
Negative.
The free versions can't even natively save in game. How lame is that. There is a difference between save states, and a game save. Save states, are "snapshots" of the game taken by the emulator at it's current placement. They can be taken at any time and will reload the game to the exact state it was when saved. If a dev want's to charge for that, fine. But a game save is the game saving info in game, how do you remove a feature from the game itself. That's bull.
The only way I would ever purchase an emulator is if it were released by the company that designed that platform in the first place. So if Nintendo went out and made a reasonably priced snes emulator I'd gladly pay for it. But I refuse to buy something from someone using other people intellectual property. The dev may not be selling roms, but he/she knows full well people are illegally downloading roms to use on his/her product. And it was created with that intent and they are making money of off it. They are making money off Nintendo, and I'm pretty sure he/she isn't sending them a check.
I will not be buying this, and I will be emailing all the companies involved to see if this can be stopped. I would rather it be shut down, than pay for what should be free. The only reasons emulators got by on the PC as long as they did was because they were free, and thats how it should be now. Unless it was an official emulator, I wouldn't mind throwing Nintendo a couple dollars for infinite nostalgia.
