I've tried that. The game still crashes, regardless whether I try wii_handle_n = dll_open("dll\\ackwii.dll"); and put the dll into a DLL subfolder or I use wii_handle_n = dll_open(".\\ackwii.dll");

However I noticed that the handle is set correctly, even without WDL file. So it must be some other function relying on plugindir. I'm not doing much else interesting than calling functions directly from the DLL.
Only using a WDL file fixes this for me.



As to the Wiimote DLL I'm using some old public domain C++ source which is no longer maintained, so I started fixing bugs and implementing proper IR support on my own. Things work pretty well now - only supporting the Classic Controller will need some rewrite of poorly designed functions from the original code. I wanted to work on this after January when exams are finished.
