Frog Feast was developed in 2006-2007 by CD-i member Charles Doty. Charles released a simplified source code after releasing Frog Feast. With this source code, other aspiring CD-i developers would have a chance to easily develop CD-i software. It took another 10 years before that happened, thanks to Gameblabla.
However, he had trouble finding out how the sound was working and he was only able to create a basic version at least. In our making-of of this game he shares the troubles he had while developing it. He also promised that, when better tools and a better source code would be available, he would love to try it again.
That time has come thanks to CD-i member TwBurn, who created his own CD-i title: Nobelia. Gameblabla: "Working on redoing Super Quartet on CDI based on Nobelia's source code this time with the new GCC-based toolchain. I would like to thank TwBurn for Nobelia and murachue for his updated toolchain (that works on Linux!).
[Thanks, Gameblabla]
