But anyways, no, Castlevania's Easy Mode was only in the Famicom cartridge version.
The only other US releases of Twinbee games that I know of are download-only: Detana!! Twinbee PCE released on Wii Virtual Console and the "3D Classic Twinbee" (based on the Famicom version of the first game) released on 3DS eShop.
Six stages to Moero Twinbee? I was so close to "beating" it then (is like the first game which just loops, I think?) It's like get the lasers and mulit-ship and you are a destruction machine, until one tiny little enemy bullet (which could even be obscured by the background on that last stage, as I recall) slips through.
