Super Marina World - a note about the version history

There are at least 7 known releases of Super Marina World, a Japanese hack by kona. The first 5 can be hard to tell apart, due to the lack of version numbers or other differences on loading the game.

[1] kona's original Japanese release
[2] kona's first English version
   "SuperMarinaWorld_EN"
The first English release. This one is popularly distributed since it was played by raocow. Also fixes some semi-softlocks on the overworld, where you could warp into a world by unlocking it via world 9, and not be able to leave without revealing the star you entered from.
[3] kona's update, 2013-9-11
   "Super Marina World September 11 2013"
   https://bin.smwcentral.net/u/12382/Super%2BMarina%2BWorld%2BSeptember%2B11%2B2013.zip
The version kona submitted to SMWCentral in 2013, which was promptly removed due to its broken music; later archived in SomeGuy712x's file bin. Contains several level design and graphics fixes.
   One way to distinguish releases based on [2] and [3] is the water graphics in 2-4: [2] has cutoff water tiles, while [3] has a custom animation.
[4] aterraformer's vanilla music edition, "1.04"
   "Super_Marina_World_Fixed_f3en5"
   https://www.speedrun.com/tools/Super_Marina_World_Fixed_f3en5.ips
Intended to prevent crashes by replacing all music with vanilla music, this replacement was done incompletely (some of the custom music survives, particularly in bonus rooms). It was also based on version [2], the unfixed level version.
[5] SuperMaks' AddmusicK edition, 2017-12-23
   https://bin.smwcentral.net/u/26276/SuperMarinaWorld.zip
This version prevents music crashes by reinserting all the music using AddmusicK. It was also based on version [2]. For some reason this fix was accepted at SMWCentral, despite that the author had been inactive for over 2 years prior to the update, and it wasn't even based on the version kona had submitted.
[6] Karisa/Zeldara109's merged edition, "v1.6", 2018-9-7
An attempt to resolve the mutually exclusive fixed versions by merging [3] with [5]. I added an arbitrary version number on the title screen for the sake of differentiating it from all the others, but it's otherwise unchanged.
[7] Karisa/Zeldara109's bugfix patch, "v2", 2020-2-2
   https://www.smwcentral.net/?p=section&a=details&id=21832
   (download includes both v2.2 and v1.6)
An extensive update to [6], including a variety of graphical fixes (some of which required remapping), more extensive overworld path unlocking fixes, and full saving including star coins and 3up suns. More details and a full changelog in the included readme.
