Japanese halfhack of Super Metroid that applies some ASM patches and forces a complete Reverse Boss Order experience. Ridley first, Bomb Torizo last. Very well-done.

Hack with some unique ideas. Certainly better design-wise than aigamerDS' RBO series. Cool to figure out the puzzles and locations of all the items, but I got stuck at GT for a long time before realizing that my method takes too much damage. (hint: there's one TAS-only way to do it and one RTA-doable way to do it. You have all the items you need at that point.)
Bosses get harder and it makes sense, because normally in RBO they would get easier as you went on. Phantoon has been buffed a decent amount. I really didn't like the room before vanilla Speed Booster hallway, with the huge maze. My mistake was coming there without Varia instead of exploring elsewhere cuz I was being dumb. Come back there with Varia. Spore Spawn was really hard, but you can actually get him down in a pattern as long as you stay focused-ish.
Other than that, some of the stuff here was laid out incredibly well and was fun despite being really hard.

Annoying maze in Norfair and garbage SpoSpo aside this was pretty neat for a halfhack. Some interesting ideas in here.

I really liked that there were a lot of items to find. Definitely made this more enjoyable than just having them in vanilla locations.

It's definitely not an easy hack. Requires some advanced techniques. It's mentioned in the readme file. Also there was a noticable difficulty spike after Phantoon.

Giving this 3 orbs. If you don't mind halfhacks it's even 4-orb worthy.

I recommend it.

Played this a couple years ago after really liking GR2 half-hack and didn't get very far. I had fallen for a trap early on thinking certain normal room and door connections were blocked off and missed a very important item when not finding a hidden passage. Tried it again with more attention to detail and had a great time. The author brilliantly routes you through a RAMBO, not just RBO. To get 100% you pretty much have to go through every room multiple times after getting upgrades, there are 256 items!! I would recommend keeping a written log of unobtainable items as you go along to save time on the back end, if you're into 100%. The author does mark a dot on the map for every item, but sometimes there are two items in the vicinity of the same dot. Tons of fun puzzles and wacky boss alterations like GR2 half-hack. The aforementioned maze in pre-speed is tempting to do without Varia as Sapphron mentioned, but not doable or necessary at that point. The bosses weren't that bad once you figure out the vulnerabilities and patterns of some of them, but the increasing difficulty was very well done. There's quite a few grey doors linked to progression, but don't forget to check for enemies killed in the room. GR2 is a really creative hacker and would be really cool to see an original hack next. Recommended with caveat that it's long, somewhat challenging, and still a half-hack.
