[1] Wonderdog is based on the game engine that was used for the Amiga version of Chuck Rock 2. From author Dan Scott: "Wonderdog was coded for Mega-CD, and then Chuck Rock 2 for Megadrive/Mega-CD was based around that engine. I then started Chuck Rock 2 on Amiga, and after, we decided to convert Wonderdog to amiga too."
It is interesting to note that it is the exact opposite of what happened on Sega platforms (Chuck Rock 2 using the engine used originally for Wonderdog).
[2] Distributed in Germany by Bomico and in Italy by Leader.
[3] The EHB mode is only used on the title screen.
When you find a hidden bonus room during play use the cursor keys to move around (up and down are reversed). If you scroll the screen all the way to the right and let wonderdog go off the right side, he will appear back in the main game, but will start walking to the right and the level will end.
