I fully support Nintendont, but here the devo-exclusive features I know of:
Wireless BT controller support for non-nintendo controllers (DS3, OUYA)
Wired/Bluetooth keyboard support (Nintendont might support wired, not certain).
Wired XBOX360 controller support without an adapter
Screenshots
Image stretching to remove the black bars on the left and right of most HDTV's
Dynamic widescreen toggling in game
Forcing wireless controllers to connect to a specific controller slot
Modem emulation
Wireless debugging
Slightly more stable than Nintendont with large 16MB/128Mb memory cards (?)
Memory card image on the Wii's internal NAND (seems like a bad idea to me, but it's a feature)
That's interesting. Let me go through your list:
"Wireless BT controller support for non-nintendo controllers (DS3, OUYA)"
Would be nice to have this in nintendont. However, those controllers are costly and FIX94 doesn't have much money. Therefore: This won't happen. But it isn't that bad: The WiiU Pro controller is a perfect solution right now. And people which don't have on can at least use an arbitrary HID USB controller or Wiimote+Nunchuck (which devo does not support). So there are enough controller options in nintendont
"Wired/Bluetooth keyboard support (Nintendont might support wired, not certain)."
Would also be nice to have this and maybe FIX will add it one day. Though, I dont no which games need a keyboard.
"Wired XBOX360 controller support without an adapter"
See first one.
"Screenshots"
That's definitively somthing I wuold love to see in nintendont. And I guess it will be implemented one day.
"Image stretching to remove the black bars on the left and right of most HDTV's"
Would also be great to have this. However, I think this is quite tricky to implemement.
"Dynamic widescreen toggling in game"
I recently asked fix if an ingame menu would be possible, in which one could toggle some settings. He said yes. So maybe this will come someday. Definitivel something I would love to see.
"Forcing wireless controllers to connect to a specific controller slot"
Not sure how this is handled in nintendont. I only play alone.
"Modem emulation"
Is on the Todo list.
"Slightly more stable than Nintendont with large 16MB/128Mb memory cards (?)"
Don't think this is the case?
"Memory card image on the Wii's internal NAND (seems like a bad idea to me, but it's a feature)"
Intersteing feature. However I prefer to have my saves on my HDD.
You forgot that afaik devo also displays your playtime correctly in the Wii's daily log, which is also a nice feature.
So, yeah, there are some things that nintendont can still learn from devolution. However, since nintendont has better controller options imo, supports different formats of games (iso, fst, compressed), supports different video modes, has Triforce support, real/burned disc support and BIOS support, I will stick with this one.
