I'm not sure what you did wrong. The "change proadhocserver IP address" should be blank for the host. Are you sure you have the same version? Check by reading the ULUS1012309 thingy with numbers at the top of the PPSSPP window when you load the game. You can also try renaming the AdamN build ppsspp.exe file to the same thing as each other (so make sure they both have (3) at the end or w/e as long as it's the same for btoh), and make sure you opened that file and not the regular ppspp.exe file that you had, when you open the program. I can't think of anything else at the moment. If you want to try connecting with me later, PM me
