My name is Marcin. On this page you can find software I wrote since I was a child. These are all free programs, I am writing them as a hobby. Recently I'm contributing to open source on sourceforge.net. If you want to find out more about me, look at this.

Hexplorer, a program I'm currently working on in my free time can be downloaded from here. It is free hex editor for Windows, licensed under GNU GPL. This program was created as an answer to my needs, I hope you'll find it useful too. The program is currently not evolving due to lack of time and it's complexity, I'm just fixing bugs, so I would be very pleased if you wrote to me and send suggestions and bug reports, I could improve and debug this program better then. Current version is 2.6.
