Now for the last step. We have to tell CYGWIN where it can find the PSPSDK (which the toolchain just installed) and the toolchain. To do this, we need to change "C:/cygwin/cygwin.bat" to include the paths. So, close CYGWIN, and navigate Explorer to "C:/cygwin" and right click on cygwin.bat. Select "Edit" and a Notepad window should appear with the following (you'll need to replace all instances of "C:" with "D:" or "E:" or "_:" if you installed CYGWIN on a drive other than your "C:" drive):
@echo off

C:
chdir C:\cygwin\bin

bash --login -i

Change this to:
@echo off

C:
chdir C:\cygwin\bin

set path=%path%;C:/cygwin/usr/local/pspdev/bin
set PSPSDK=C:/cygwin/usr/local/pspdev

bash --login -i
