I know this is a very old post, so I hope I don't get any warnings about this since I'm adding info and a sort of review here since this wasn't an official patch for me to review through the normal channels.
First of all, thanks a ton for putting all of these amazing hacks into one single patch. I had this game patched since right around the time you first released your last version of it, but I only got around to playing it yesterday. I'd never actually played any of the Metroid hacks before and it's probably been at least 10 years or maybe 15 since I last played NES Metroid.
That being said, all of these major improvements made the experience much more enjoyable than I thought they would. I didn't beat the game so fast that I saw Samus rocking the bikini, but being that it's been so long since I played and I forgot pretty much where everything was, I thought it was cool that I got her to take off her helmet, which is something I never was able to do back in the day. Not sure where exactly that puts me time-wise, but it's faster than I've ever beaten the game before.
I only noticed two bugs during my time playing it. Not that they're game breaking or that I'd expect anybody to fix them. God knows where the fly in the ointment would be when you've got all of this stuff going on.
1. When I was in the save screen and had 115 total missiles, it read "25 / 1 5". For some reason the middle digit was missing. I didn't save and check this every time I got an upgrade, but any time after my next pickup that I saw the save screen it wasn't missing a digit, all the way to "250 / 250". (I was trying to beat it "fast" and couldn't figure out how to get that 2nd one near Ripley with that terrible jump so didn't quite max out missiles).
2. When in the 2nd to last room before Mother Brain, there are 3 Metroids that spawn by the door that are easy to farm for missiles and energy. When you go back into the room to the right, sometimes one of the Metroids will go right into the door and grab you instead of hanging out underneath a platform by the door. When this happens and you kill all 3 of them the screen will do this weird scroll to the left, you get all 3 powerup drops, and then Samus is invisible. You can move the screen around back and forth and eventually she'll show up on the lefthand side of the screen and you can go through the door to the right again as if nothing happened. Not a big deal, just thought it was weird. Maybe the original game did this too?
Anyways... Thanks to EVERYONE who made these awesome upgrades to this NES classic!!!!! I'm simply amazed that you were able to do so much stuff with this game.
EDITED TO ADD:
I highly recommend this hack to any fans of the original Metroid and the Metroid series in general.
If the original hack authors of all of the various hacks used together in "Galactic Edition" were on board with the idea, I think it would be great if this compilation patch was given its own official patch release.
New Game + is cool.
With everything fresh in my mind I was able to charge through the game and pick up about 170 missiles and 5 energy tanks and blow by Mother Brain quick enough to finally get the bikini ending.
