Also known as: Dorque and Imp, Dorke n' Ymp
|
Dorke and Ymp is a commercially-released homebrew SNES platformer that was originally developed by a small team of Swedish hobbyists in the early 90s, who eventually shelved the game after failing to find a publisher.
A few prototype builds were released online, with homebrew publisher Piko Interactive later being responsible for the game being finished and given a physical cartridge release. A Steam release using a customized version of the Mednafen emulator followed about a year later.
Uncompiled Code
Various fragments of audio-related source code are scattered throughout part of the ROM, possibly as a result of unused ROM space being filled with uninitialized memory.
