Hi, Im new to DS development and I am trying to run dualis. The problem is that my XP install is a virtual machine with no sound. When I try to start dualis I get "apu_init failed error code = 000000" then it crashes when I click ok. I tried editing the ini file to set "emulatesound=0" instead of 1 but I still get the same error. Is there any work around to this?
