Alternate name: Not Native
The first video game about Non-Native was released in 1991.
This does not include engine remakes (ScummVM, freedoom, etc.. are native applications that use original data but not original executable code). It also does not include cross-platform systems like Java (the Java code is natively executed, as intended, by the native Java environment).
