Btw, a bit of an update on this (if anybody will actually care to read it)
I was wrong in my last post, Brazil was a goldmine for Sega Genesis and Master System users, the Genesis sold really well here and outdid Nintendo. This was back when Brazil was under military dictatorship and we had an blockade on foreign technology. TecToy was one of the very few companies that had permission from the governament to sell Sega consoles and technology, they managed to get a unique contract with Sega, allowing them to even legally manufacture Sega Master System clones.
TecToy was also the pioneer in brazilian videogame making, with most of their games being legally done mods (or hacks) of other existing games, taking known brazilian characters (like the Monica comics or Chaves (popular funny mexican sitcom that was more popular here in brazil than in mexico)). Its akin to what the old console games did with their US localizations.
Duke Nukem 3d for the Genesis was done under contract with GT Interactive, not 3dRealms and required huge efforts from the dev team to get it working on the limited hardware. The devs worked previously on Phantasy Star's brazilian translation and with that they were able to... reverse some code and know tricks to get proper 3d working on Duke Nukem.
Here's a video interview with TecToy's CEO (at the time, he was one of the lead programmers):
