Hello,
I just have released a patched version of GB Studio 1.2.2 that is able to export the game as a pocket game.
https://github.com/BestPig/gb-studio/releases/tag/v1.2.2-1-analogue
So you should be able to port officially the game on Analogue Pocket without the pain of migrating it to a higher version of GB Studio.
Let me know if you encountered any problem with it, I just have tested it with the default project.
