Final Fantasy I older app apk

I have an old Final Fantasy app on my phone but it's no longer supported due to the Pixel Remaster version being released. I heard that there was a version with bonus dungeon Soul of Chaos but my version is too old and can't receive updates so I can't get it, and the Pixel Remaster removed them. I tried searching for it but it's confusing looking for the correct one and many didn't have detailed descriptions beyond "it's ff1"

Anywhere I can find this version with the bonus dungeons?
