The Great Metroid Construction Collaboration Hunt - Post your resources here!

[OmegaDragnet9]

Tonight I restored all the latest revisions of my attachments to this thread. What I contributed is back where it should be.

It would be great if my fellow metconsters would follow suit.

Much can be salvaged before February of  2024 (on the Wayback Machine) but there was an explosion of contributions from this year that I'd rather not lose to the sands of time.

Metroids Stay Dead
Speed 1 Version

(Was trying to figure out how to do this for a while, and seeing what Mystii was doing with the Zebetites made me check how the vanilla game used the Speed 1. So credits to Mystii, Scyzer and P.JBoy for helping me figure this out.)

If an event matching the metroid's Speed 1 is set, the metroid will not respawn when you reenter a room. (This is Parameter 1 in SMART.)

The exception is for Event 00. Why? Because every gray door sets Event 00, and would result in no unedited metroids spawning if a gray door were unlocked at any point before you entered the room.

This gives you the option to have returning metroids, if you so desired.

This is best used with JAM, dewhi100, or my own room-clearing event PLMs.

It might be some time before this gets added to resources, mainly to make sure there aren't any bugs I missed.

Assembles in xkas and asar.

Intended for usage with the SMART editor.

Transparency Line Fix

P.JBoy's edit of Black Falcon's Transparency Line fix that was featured in the Super Metroid Mod Manual.

Credits to Black Falcon, P.JBoy, and Neen (for explaining the changes.)

Another set of edits I added that should be discussed:

-Commented out the transparency fix for acid (there is a better fix that affords palette tweaks, not featured here.)

-Added another row of water tiles from elsewhere in the tilemap. This is completely necessary because I encountered an issue where a transparent row of air tiles replaced the top row of water. What would happen is Samus would splash in and out of air, and the water physics were still active in that row of air. This corrects that problem.

(I know before the Metconst purge I thought I saw a similar fix floating around.)

Acid Fix

Meowmaritus was kind enough to share a fix for the transparency line and the background for the acid imposing on the air above the acid.

Similar to squishy_ichigo's Acid Mod, this allows the acid to be set to any palette blend instead of just using the Power Bomb door colors.

Why is this to be used instead of the original acid mod?

The original acid mod allowed the acid palettes to be chosen much the same way as lava in the FX editor. However, the lava palette blend was only setup to handle two colors, as introducing a third color would result in the background being tinted that very color. (The effect is actually very ZM looking and does look cool with lava.)

The problem with acid is you could either just have the whole room filled with the acid background, or you were forced to have the acid rely on two colors. The former was too overpowering and the latter was too weak looking, and  the result was inferior to simply leaving the original door color intact.

Code entirely by Meowmaritus. The only thing I provided is the palette blend table (courtesy of P.JBoy) as well as the legend for the custom palette blends. (Palette blends taken from my current project.)

Not shown in the videos, but the vanilla acid colors are provided in the palette blend table.

Use blend 82 in the FX editor for vanilla acid.
88 for a richer acid.
8E for a dark green acid.
94 for a dark blue acid.

[OmegaDragnet9]

I recommend people use Meowmaritus' acid fix, but I figured it would be worthwhile to provide my disassembly of squishy_ichigo's acid mod. (For documentation's sake.)

Enemy Deletion Prototype

Room ASM that deletes all enemies in real time if a particular event is set. (Event PLM not included.)

It does have a PLM; and it serves only to have a PLM argument and set that value to a specific RAM address. (If you have an Event PLM, make sure both PLMs have the same low byte.)

The Room ASM ($FCC0) reads that and determines which event to check against (using the value determined by PLM $FEC0. Make sure you place that PLM in the room editor.)

Known Issues:

1.) It is best to make sure enemies needed matches all the enemies in the room (or you will have a goofy jumpscare when they suddenly vanish.)

2.) I have fast door transitions and noticed that enemies appear in the room momentarily when the room is loaded.

3.) Enemies not set to process off-screen, even after the room is loaded, their graphics can be visible for about a frame when you walk into a new screen.
