I also wish that there were some documentation for DSKey. I had imagined such a program to use my DS as a controller for PC emulators and now it is real! I totally can't figure out how to connect to my PC from DSKey. This program is so underground. There are very few mentions of DSKey or DSPad on the internet or DS forums. And there are too many settings in DSkey to configure that I am just unsure of, I need a tutorial or guide. I can't even figure out how to get DSKey.exe to use the correct IP, there is no .ini file or anything. Also, DSKey does not recognize my home router, it recognizes my neighbor's router though lol. But when I tried DSKey on my son's DS, DSKey DOES recognize my router. So either it is my DS, or it is my R4 DS. I will try my son's flash card in my DS to see if it works. I consider myself pretty savvy, but even with my son's DS recognizing my router, I was not able to setup DSKey on the DS or the PC. Would someone that has DSkey working please post some pictures of the settings in their router, and in DSkey? I came to this forum kind of expectiong to find a GUIDE or TUTORIAL, and maybe some answers. But after a couple of days, and reading ALL of the posts in this forum, I have found ZERO answers.
