I found a way to get around the softlock in the GFS section, for those that might have gone there and accidentally screwed themselves over when going there.
- One easy way to do it is to download the AM2R Launcher and the AM2R 1.1 version.
- Once both are downloaded, run the AM2R Launcher, so the v1.1 of AM2R gets updated to the latest v1.5.2.
- Run the updated version of AM2R and create a dummy file in each of the save slots, simply start a game and run into the ship to save immediately.
- Now that you have your AM2R updated to the latest version, dump your save file of AM2R with either Edizon or an save file dumper for the Switch.
- In your PC, go to the following location:
C:/users/(Your Username)/AppData/Local/AM2R
- Inside that directory, you'll locate the dummy saves you generated in Step #3. You can pretty much Copy-Paste your Switch save files into the PC version
- Now that you have copied your Switch save files into the PC version, run the game, and go through whichever section you are stuck at, be it the GFS Elevator or the Tower Sentry boss. Defeat the boss, and save, or get out of the GFS section and save somewhere else.
- With your saves now done in other places and in a safe place, copy them back to the Switch SD and restore them back with Edizon or whichever save manager you use.
- Run AM2R on your Switch, and now your save files should be ready to keep obliterating Metroids!
Do take note that this is just a workaround to be able to finish the game in the Switch in case you encounter one of the two game breaking bugs (or both like in my case lol).
It'd still be desired to have both of these game breaking bugs fixes in a future revision, and hopefully the water SFX bug as well.
Hope this helps others!
