Stupid topic and quite an annoying first post, but as fgg pointed out, it won't be coming out anytime soon, if at all. But really, just play the GBA version. Aside from very minor enhancements to the interface and a new (and tiny) gameplay segment with Shooting Star Rockman, you're really not missing anything. The graphics are identical, the music is the same, the battles are the same, even the dialog is identical apart from the new SSR part. It's quite the lazy port, and really not much to be excited about.
I can probably name all the enhancements off the top of my head-
1- has a short crossover segment with Starforce about 3/4 into the game
2- menus look slightly cleaner and more updated
3- minimap on the bottom screen
4- you can now run away from battles using the L button in the custom menu
5- battles have voice clips
6- you can swap out Megaman.exe with Geo after beating the SSR crossover part
It actually sounds a lot better than it is. These enhancements don't add up to much really. Had they done an all out remake and made it a TRUE crossover, thereby altering the events of history in the game and starting BN anew, THAT would have been quite an interesting concept and original at that. Too bad they got lazy. Just play the GBA game. I don't see any reason to hack such a lazy excuse for a "crossover".
