A user on a forum like The Daily Click or GameMaker Community posted a beta of their side-scroller. A scene ripper (likely European, given the syntax) bundled it, added an error due to missing runtime libraries, and uploaded it to a private FTP. Years later, YOPO found that broken dump on an old hard drive or Usenet archive, compressed it, and released it as a "reworked repack" to preserve the error state.
Rutracker.org has a massive archive of YOPO repacks. Use Cyrillic search terms: "Tims Adventures бета ошибка репак" or simply search the raw keyword. tims adventures v013b err yopo repack
