did you try pressing shift and f1 at the same time
try pressing 'shift' + 'F10' at the same time, then select 'save state' and choose where you want to save it. when you want to open it again do the same as before but click 'load state'.
Save on an 128k at options- emulator-save type-flash 128k then the message of corruption or damage will not appear and your game after you beat elite four will probably not be erased.
it probably doesn't save because it is the fake version or a gba ROM.
If you are using an emulator like VBA to play Pokemon Fire Red then you do not save as you normally do. You save using the emulator controls.
you download the randomizer, download an emerald ROM and an GBA emulator for mac, then you run the randomizer and go to File, Open, then select the emerald ROM, set the settings you want, and then file, save as. Play the new ROM you made with your emulator and you'll be good to go.
In Pokemon Liquid Crystal, saving may be disabled if you are playing on an emulator that does not have the save feature activated or has not been configured properly. You may need to check your emulator settings or try using a different emulator to enable saving in the game.
Because if you forget to do these things and if your playing a Emulator, your file gets erased. Do these things:Go to options, then go to emulator, then go to save type then click on Flash 128k. Then go to file. And go to save game. Then click on the first one. Then it will work. ! If you still need help, go to Youtube and find "How to fix saved data in Pokemon Emerald". Then it will have more information how to get your game back. If you already started a new game, then your old file can't come back. P.S. It helped me also!
If you are using an emulator VisualBoy Advance click tools and there save type. Try both of the ones with the K or Kb as the unit.
Your Emerald is deleting its save file? Possibly your emerald or diamond version could be corrupt, either from age or action replay codes. I have a Ruby version where the clock battery has run out, now it says the launch is no. 9999 lol. I'm afraid there is nothing to do except get a new emerald version... somehow.
128k, go to emulator>savetype>128k
Pokemon save
save prof. birch
You must have not installed it wrongly or it is not the version required in your machine.
