Hi. RetroBat is a free project, you didn't buy it, you made a donation. The full setup program is a reward for those who donate to the project. The main purpose of RetroBat isn't to provide games, but being a retrogaming software distribution dedicated to emulation, so basically an already configured frontend with a advanced integration of the emulators options. You need to provide yourself the games. Please read carefully the description and the different posts before giving money. If you think that it's a misunderstanding, you can ask for a refund.
