In case you still haven't, I found SM menu data. Took me just a few minutes this time.
Replace the values between offsets 4200-421F with:
0C 00 FF 2F 00 01 02 03 08 07 06 0B 0A 09 05 04
00 00 06 00 01 03 80 00 20 4A 7A 46 97 D9 87 46
That'll make all the icons to appear. However, some of them won't work as the "obtained" flag hasn't been triggered, and that includes the Pelago one, so even with this you'll be unable to access it.
I don't have a SM save near that point to look for the constant, nor the time to get there from a freshly started game, so if you still going through the game, I'll have to leave that part up to you.
PS: Already checked 470, to no avail.
