Thanks for the tips! Already got mighty guard and all the songs, as well as some good locations to grind various mix components (Dragon Fang and Turtle Shells specifically). Not sure where to get Dark Matter though. That shit is basically an I Win Button. Might still try for Bahamut since the trip up to him is pretty easy. Need to double check prices for Phantom Village equipment. Any good Gil grinding spots? Aside from Gil turtle?
As an aside: This game has put me in a nostalgic mood for FF. What is considered the definitive version of FF1? Haven't played that one in like a decade. Thinking about playing it when I'm done with this run. I have access to PS3/4/TV, Wii U, PC, and of course, iOS.
The NES version is the original version, if you want the old-school experience.
The Origins version (PS1/PSN) is based on an earlier Wonderswan color port, and has some slight gameplay tweaks: characters will now automatically retarget enemies if their old target dies, unwanted spells can now be replaced, the inventory system was rebuilt to be more like modern FF games, and boss hp was increased to match some of the difficulty changes. It also has an optional easy mode with reduced difficulty. It also adds some music.
The Dawn of Souls (GBA) version of FF1 includes increased exp gains and changes to the magic system, but it also includes four optional dungeons. It is generally easier than the original version, and has lots of new purchasable items and significant changes to stat progressions. It also further increases the hp of bosses and certain other monsters. Also includes some music changes, I believe. Screen resolution is of course lower than the other non-SNES versions.
The 20th Anniversary edition (PSP) is similar to the Dawn of Souls version, except it adds an additional optional dungeon and associated superboss.
FInally, the smartphone version of the game is basically identical to the 20th Anniversary edition, except it is missing some features of the PSP version and suffers from some serious bugs (such as being stuck with mostly minimum hp increases on level-up instead of the normal randomized increases on level-up).
So, I would say that any of the Origins, Dawn of Souls, or Anniversary editions would be good to play, based on your preferences.
