It's based on the Little Brown Books and is compatible with Swords and Wizardry, and it's a blast. There is a free PDF supplement featuring the Paladin, Geiger, and Chronomancer classes as well as the Comeliness Ability Score, and new Races and Psychic disciplines. BnB uses a roll to cast system for casting spells and a different roll to manifest system for psychic powers.
I decided to work up Wookies for it as both a playable race and as NPCs.

WOOKIES. AC 7 | HD 2 | #E 2–12 | MV 40’ | THAC0 19 |
#A 3 (1d8 or by weapon) | SV14 | ML 10 | AL Neutral or Chaotic | XP 20 | T (IV) Description: They are a species of tall, hairy humanoids from another world. They are quite strong and have been known to rip people's arms out of their sockets when provoked.
They have extendable claws, which they use for climbing; using them for anything else violates the Wookiee honor code. Despite their fearsome appearance and volatile temperament, they are regarded as intelligent, sophisticated, loyal, and trusting.
When angered, Wookiees are known to descend into a berserker rage for 1d6 rounds and deal +2 damage with melee weapons and gain 2 damage reduction. They can do this 1/day.
