Hey there!
The setting is probably not coming out any time soon, but The Old School Referee book on my itch page is the Referee companion for S&F 2e.

For those who want a template, the above file is my own planned submission for this jam. It's an affinity document, which is now free to use.
Feel free to use this template, or create something all on your own!
*For the most part* the adventure itself is the same.
The dungeon has been completely rebuilt into an actual dungeon, not just a list of rooms and an encounter table.
The regional map is the biggest change, with the "base" and "goal" hexes being put on opposite sides of the map now, causing players to have a reason to actually... walk in the Harwood.
The other biggest change is in the formatting of the keys. A consistent format has been applied throughout the adventure, making it easier for Referees to know what is immediate information, and what is hidden.
Thanks for the question!
The Magic Dice system is pulled straight out of GLoG, so I have some really good news for you! There are about a billion GLoG wizard schools, which should translate almost straight across, but may need some tuning for the system.
Here's a huge (but still incomplete) list: https://attnam.blogspot.com/2018/08/d50-glog-wizard-schools.html?
As long as you remember to scale spells with Dice and Sum, you can make just about anything work.
The Referee section has guidelines for quickly putting monsters together, but no official bestiary is planned. That said, almost any OSR bestiary will work. I personally use the Monster Overhaul, but if you want a free one, the BFRPG bestiary are also excellent.
I think the only major difference is the Unified Save, which is based on HD. That *will* be on the Rereree Screen I'm hoping to make.
Great Question!
I counter: Do you know the exact price of all items on the real world?
An adventurer can likely estimate the rough value of an item, but a merchant would know down to the copper the value of every item in a dragon's hoard, and know what to keep vs. what to leave behind, if it came down to it.
Changing the death system was mainly an issue of simplicity for me. I was really pushing myself to keep the rules as small as possible.
That said, I think you could absolutely swap in the old wounds system for the death roll. Combatants, rather than their d6 death roll benefit, can take +1 wound per chapter of combatant before dying.
