Well, looked around, I can't find any console commands for this game yet.
On the plus side, I did go back several levels worth of saves, to pre-3rd Elemental portal, and redid the entire game from that point. I chose ICE instead of FIRE portal, and made sure I talked to every Homestead NPC each time, and ported back out then back in a couple times.(To a random spot on the world, then back to End of Time, etc.)
Not sure what of the above fixed it, but I was able to open all the portals except Forbidden Portal, and I have two Bloodstones left. 13 Star/Bloodstones used or just found, 2 leftovers. 16 total in the game, apparently, I missed one somewhere.
One thing of note, I did all of the above with Cassandra still alive. Dialogue indicates the game is SUPPOSED to work if Casssandra is dead, but the Portals definitely DID NOT open for me when I used bloodstones after she was dead.
I lost out on a couple lucky Armor and ring drops, but oh well. The game looks to be completable now.
