Freelance developer of entertainment software
(from Spain)

List of applications developed by Jordi Perez, from year 1984 to year 2024.
Also includes magazine collaborations and other projects.

This page does not have links to direct downloads although in some cases there are links to the official pages of the applications where you can find different downloads.

This list is intended as a reference to avoid incorrect attributions of authorship and as a basis for more detailed searches on the Internet.
Of course, this list also exists to show you my work in case you find something that may be useful or curious among everything I have developed.

Thanks for your visit.
