Finally I could have a timeframe enough to finish my MegaMan 4 repro!
Some pictures of the monstruosity:
Altough very similar to the stock MMC3, I couldn't find this clone's pinout anywhere.
So, I think it would be nice to share it here:
The small IC is a demux I made with an LS00, and yes, the IC is labeled "LS00":
Hope this can help someone else in the future!
