Planet Virtual Boy

I'm kinda curious how people make games,turn them into roms and stuff. I need to know what kind of tools are used,in other words, How do they make these homebrew games?

You should be able to find all the info you need on the dev forum. This post by DogP might be useful for example: http://www.planetvb.com/modules/newbb ... ost_id=9948#forumpost9948

The Dev Wiki has some guides for setting up, example code and will help you understand how the VB handles graphics: http://www.planetvb.com/modules/dokuwiki/

Also, look at my page on how to start making games for the Virtual Boy.
