After 18 years of developing new games for classic systems, John Dondzila "retired" from that hobby in late 2014/early 2015. However, he made arrangements with other homebrew makers to produce some of his games.
On Oct. 1, 2018, publisher 2600 Connection announced a "Rack Test" version of the very first homebrew Odyssey² game, Dondzila's Amok. This cartridge included a switch that enabled players to select which of the game's 100 levels they wanted to play. It came with a manual but no box. The label and cover art are identical to the original with the addition of yellow starburst highlighting the words "with Rack Test!" Originally sold for $25 plus shipping.
The revised manual was handled by Tim Duarte; Scott Stilphen produced cartridges and labels. Both worked on game testing.
