Well this brings back some old memories :) We built our own KLT point tracker to make "Onscreen Text Substitution" stick to moving cars and/or during camera pans. We reverse engineered Winny (a Windows-only filesharing software) to build a Linux server with WebUI so that you could conveniently remote-control a server in Japan. We built a C-like language with AOT compiler that actually creates machine code to make particle effects render faster. We used spectrogram analysis to assist with separating the audio track for along karaoke animations. And of course there was multiple competing xdcc servers. And then there was the truly crazy stuff like a TSR bootloader for your PS2 which would hook drawing calls in memory so that you can fan-translate video games, too. We truly had an insane amount of cutting-edge tech back then, if you consider that this was just some people's hobby to enjoy Japanese content.
