Notes

A look at the header shows that this ROM is version 0.24, dated Sept 26th, 1990, compared to the retail game’s version 0.25 and Oct 4th 1990.
Similarly to Bubble Bobble, there is a bunch of minor miscellaneous hex differences dotted throughout the whole ROM which has shifted the data downwards, making it look more different than it really is.
Judging from the closeness of dates between the prototype and the final version, I’d say there’s most likely no noticeable differences in gameplay to be seen here.

A huge thanks to Armageddon Potato for this bountiful lot as well as togemet2 for documenting and analyzing parts of the lot!
