It was canned due to the cost of manufacturing the cartridge & believe it or not, due to the release of Thunder Force IV/Lightening Force: The Quest for the Darkstar. Frederic Hodue will release the ROM as a happy new year gift in 2018 https://mobile.twitter.com/VGDensetsu/status/941259658362347521
Very cool. That is an awesome gift and something I'm now looking forward to. I'll have to keep up with that twitter.
As soon as Frederic releases the ROM either on facebook or somewhere else, i'll post here as soon as possible
