installation is very simple:
step #1 - download the latest version of minpspw
step #2 - select components for installation
once the download is complete run the installer. click "next", accept the license agreement and click "next" again. you should now be at the "choose components" screen. this screen lets you select what will and will not be installed. by default, "PSP DevKit", "SDK Samples", "PSP Link", "HTML Documentation", and "Basic Devpaks" are selected for installation, while "Visual Studio Support" and "Man/Info Pages" are not.
i suggest you leave all the defaults selected and they are all somewhat essential for developing for the psp. if you are going to be coding using microsoft visual studio then you need to select "Visual Studio Support" for installation. i will leave the installation of "Man/Info Pages" up to you
when you are finished selecting components for installation, click "next".
step #3 - complete installation
this screen is the standard "select destination" screen. you can change the location of installation, but i highly suggest you leave it in its default location when you are done click "install". once it is complete, click "next", then "finish"
step #4 - adding pspsdk environment variables
the last step to installing the pspsdk on windows is adding the pspsdk to the environmental variables. to keep this simple, i am not going to go into much detail concerning getting to menu for modifying environment variables. each version of windows is different, so just google "how to modify environment variables on windows [insert version here]".
once you have reached the environment variables menu, select the variable called "Path" in the "system variables" box and click the "edit" button. once the dialog box pops up, place the cursor at the end of the statement in the "Variable Value" box.
with the cursor at the end of the statement, add this (no spaces): ;C:\pspsdk
once that is done you are set to go. you have successfully completed installing the pspsdk on windows via minpspw! congrats! now get to coding!
