I'm not sure when Aetherbyte will have Hucards ready, & maybe neither do they(?). Maybe they're already ready, & are just being hush hush
In any case, I see no reason why the game couldn't be pixel pefect & be on a cart. However, as stated before, CD is easier for now. If you do CD, I'd highly recommend you do a straight arcade port, & an enhanced mode. For the enhanced mode, you could add some redbook versions of the tunes, & could probably use updated sprites/tile lifted from other Bubble Bobble games. Then for the music, you could have 3 options for the player to choose from, chip tunes, redbook of the original arcade audio, & some arranged versions of the tunes that switch up maybe every 10 stages, & have this selectable perhaps in an options screen.
But, maybe this is just me dreaming!
