Okay step by step guide for running windups and other programs using free launcher
Firstly windups and free launcher come as FPK files, you dont have to do any kind of copying with these, just go to the file menu in PC link and click install, first select the freelauncher file, that'll install, then select the windups file. Now start your GP32 and select game, it should show an icon and say free launcher press a to select this and a bit of korean text will appear then it'll load.
Most files however, come as fxe files, with these you install free launcher the same way, but you have to actually copy the FXE file to the GPPM folder, the readme will tell you where to put everything else.
