About Me


I discovered Grand Prix Legends in 2003. Amazed by how difficult it was to finish a single lap, I was immediately attracted to this racing sim. Bought a force-feedback racing wheel and started to practice. Studied the guides, began interested in car mechanics, but could not approach even average times. I almost gave up but the 65mod published in 2004 refreshed my zeal. Suddenly it was much easier to compete, though I never pulled together enough courage for online racing. Since I had a lot of interest in the history of Formula 1 racing, I tried to look under the cover of GPL and attempted at modding the driver.ini files to simulate the performance and behaviour of the real 1967 driving field. Later I widened my efforts at the newly appeared 65 and 69 mods. I published my mods at my web pages (now dead, but a copy is here) and it was noticed by the GPL community. Soon, however, my efforts were superseded by deeper work of Lee Bowden and others.

Around 2006, my growing family and professional interests started to drive me away from simracing. Though I occasionally returned back, I could not find enough space to continue my driving and modding systematically. With great pleasure I could watch how the now antique software is far from being forgotten. Many new developments and improvements have been brought to life. Simdrivers could enjoy many new physics mods including corrections to imperfect original physics and new features like brake fading in the 55mod or downforce in the 69mod. I must admit that my current return to GPL was also stimulated by spotting my name in the
GPL 2020 Demo Promotion movie that made me undeservedly proud. For the last three years, I am back to GPL simdriving and I also returned to where I quit – tinkering with the AI historic performance.

While everything I did was done for purely my enjoyment only, I finally decided to make the outputs publicly available. Therefore this web...
