WiiFlow_Lite/source/loader/playlog.c
overjoy.psm a38e80ee28 Just some quick fixes:
- Fixed creation of the playlog
- Fixed and changed the way Wiiflow checks for neek2o (uneek2o r92 beta 12+ req)
- Fixed IOS reloading for Wii games in neek2o mode
- Added a small delay in booting a Wii game in neek2o mode

/*
PLAYLOG.C
This code allows to modify play_rec.dat in order to store the
game time in Wii's log correctly.

Thanks to tueidj for giving me some hints on how to do it :)
Most of the code was taken from here:
