IF you see my adf.ly numbers you'll know why i talk about this:
March 2016 updated right now downloads:
CHMM2 v.2.6 - 2327 downloads
NASA v.1.4 - 2042 downloads
NASA v.1.3 - 578 downloads
DSP Firmware Dumper - 419 downloads
...
ctrWolfen v.0.8 - 87 downloads
ctrHexenII v.1.1 - 80 downloads
...
Labyrinth 3D v.1.1 - 38 downloads
So is it worth the effort to work on 3D game homebrews? (Labyrinth 3D) NO
Is it worth to work on game engine ports? (ctrWolfen , ctrHexenII) NO
Is it worth to work on something that can enable pirating for third worlder that can't buy for 15 bucks a game or for 1,59 dollars a theme? YES
1) "ad.fly" There's your problem.
2) Using popularity as a basis for doing something is silly, since only a small fraction of the 3DS's install base uses softmods and homebrew in the first place.
