I've talked here and there about #MiniBX and it came up in the discussion sometimes that the cost of the whole MiniBX project was too expensive (USD 30). I can understand people can have a problem with that.

But today, @lucasrolim has just published its #SRD under the terms of the #creativecommons CC-BY-SA License, freely available for your greatest pleasure, via: https://lucasrolim.itch.io/minibx-srd

(But I may warn you: this is definitely not a retroclone of ye olde B/X, this is a thing on its own)
