Please don't be disingenuous.All well and good, except getting games to actually WORK on Atmosphere is a painful process compared to SX-OS.
...and that's all that the majority care about.
Atmo:
- find and install patches
- convert XCI to NSP or locate NSP. Conversion may or may not work. Try multiple tools if it doesn't work first time.
- install NSP. Installation may or may not work. Try multiple installation tools if it doesn't work first time.
SX-OS:
- copy XCI to SD card
- play
Atmosphere:
- install NSP
- play
In addition, Atmosphere supports 7.0.x, and SX OS does not. Games will inevitably require 7.0.x.
