I apologize for being busy for a while and taking time to respond.
As @Tetsuya79 said, I got a bit of a loss of health.
In about one month from now, try to solve some existing problems, I’ll release rev.17.
After that, I’ll take a rest for about a year to improve my life.
It is not seriously ill! Because it only spends without thinking about development.
(Just follow my doctor’s extra advice.)
Let’s examine the matter of @matt on Linux.
According to @Acris, it seems necessary to investigate recalbox.
I think that @Aethix needs a complicated implementation,
such as which keyboard key should be selected,
implemented by changing the cfg file instead of the UI. extremely difficult.
It can not be realized with rev.17. I’m sorry.
I would like to express our appreciation to those who gave valuable opinions to NP2kai !!
Very very thanks to NP2kai users.
I’LL BE BACK !!
