Kamil „Gorgh” Trzaska
Author of Assembler Programming
Kamil "Gorgh" Trzaska is a programmer, game developer, and active participant in the international computer demoscene, associated with the Polish group Agenda and the global collective Hokuto Force, among others. An art historian by training, he successfully combines technical precision with artistic sensitivity in his projects.
His coding journey began with Atari computers, and his long-standing passion for retro hardware evolved into creating his own software, award-winning demos, and commercial video games (including LiteRally and The Rescue Expedition). In his productions, he demonstrates that classic platforms still hold enormous potential, skillfully combining nostalgia for bygone eras with fresh design ideas.

Jussi Koskela
Creator of Deluxe Ski Jump
A legendary Finnish computer game developer, trained as a computer scientist, who routinely programs systems for power plants. At just 19, during a break from military service, he wrote a game in Turbo Pascal that forever changed the world of virtual sports – Deluxe Ski Jump (DSJ).
His proprietary physics engine and brilliant analog mouse controls made DSJ a gigantic, multi-generational phenomenon. The game gained a unique, almost cult status in Poland, where millions of players enjoyed it during the "Małyszomania" era. To this day, Polish fans and modders constitute approximately 90% of the series' community. Jussi continues to develop his iconic project – porting the classic DSJ to mobile systems, and in the latest versions, he hid his own face as an Easter egg.

Szymon Makuch
Academic lecturer
A lecturer at the AGH University of Science and Technology in Krakow, a member of the "Trickster" Association and the "GameUP" Association, and an editor of law books and more.
He's always dreamed of slaying orcs with Aragorn, so from time to time he has to return to a game set in the "Lord of the Rings" universe. His research interests include the role of intellectual property law in contemporary pop culture, for example, calculating how much Weronika Marczak spent on trademark registration. He also believes the new "Highlander" starring Henry Cavill will be a masterpiece.

Internet Creator
NRGeek - a Polish YouTube veteran, reviewer, columnist, and uncompromising commentator on the video game industry. A graphic designer and animator by training, a former rapper by profession, and a passionate, tireless retro enthusiast and proud collector of all sorts of electronic junk.
For years, he has been speaking with a sharp tongue and characteristic detachment about the history of gaming, testing forgotten hardware, and analyzing the contemporary market. Amidst a sea of gaming trends, he remains faithful to the classics, cult games of yesteryear, and-above all-the Japanese Yakuza saga, of which he is one of the most devoted advocates in Poland.

From a young age, he's been involved with computer hardware, gaining popularity by going far beyond the confines of traditional electronics testing.

Łukasz's natural habitat is both modern PCs and the world of retro gaming: old operating systems, rescuing computers from the trash, and repairing components bought for pennies. In his content, he combines technical knowledge with unquenchable curiosity, proving that almost anything can be done with hardware and software. On stage and off, ZMASLO inspires a genuine passion for modification, tinkering, and exploring the history of technology from a completely unconventional perspective.
