This is a list of relevant links, a table of catered ASM snippet names, a list of helpful commands, and a table of RAM addresses for use with Chat Hacks SMW by PatCdr, streamed peroidically at twitch.tv/patcdr.
These official pages will explain Chat Hacks SMW much better than anybody else can:

These are ASM snippets that I have used or seen the effects of and personally find fun or useful. Keep in mind that people can change or delete their code after they upload it — the descriptions I have listed here may not accurately describe the effects forever. This is not a replacement for PatCdr's own automatically updated list; it is simply a reduction and alphabetization of the massive list so that I can make decisions more quickly. I probably left some out, but that doesn't mean I don't like them.

These are RAM addresses (normally left free by vanilla SMW) that users have picked out for using with their CARL snippets. I have compiled this list in case anyone has the ability to write ASM for CARL and doesn't want to overwrite other people's free RAM. The list is mostly complete (many entries were copied and sorted from CircleFriendo's "Addresses" reference file), but I don't know what every single snippet uses.
Please let me know if you would like your addresses added to this list.
Visit this filtered RAM map to see other free regions of RAM you can use.

You can make your own teleport command by running SMW locally in emulators with a RAM editor (snes9x, BizHawk, no$sns, etc), walking to your desired location on the overworld, opening the emulator's memory/RAM viewer, locating the addresses used in the above commands ($7E1F11, $7E1F17, $7E1F18, $7E1F19, and $7E1F1A), and putting the displayed values in place of the ones in the commands above.
To turn Autumn palette and sprites off, paste !w 7E1EEB 0.
To turn Autumn palette and sprites on (not recommended), paste !w 7E1EEB 80.
Changes to the autumn bit are applied when the overworld is reloaded.
If the player is stuck in a level (especially level 0/Bonus Game), pasting !mode b will instantly take the player back to the overworld, providing the game hasn't frozen.
Alternatively, pasting !mode f will restart the level from the beginning, provided that some joker hasn't changed the player's overworld position. If that has happened, see above.
If you don't want to start the level over, try simply pasting !end_level_timer FF for the normal exit and !keyhole_timer 30 for the secret exit. If you want to end the level in style with the regular exit and give the player a blue yoshi, paste !player_mode_dispatch 8. Note that none of these commands will end the Bowser fight! (That is also possible with Chat Hacks, but I will leave that for a later time.)
If the player needs some health, paste one of the following: !19 1 for big Mario, !19 2 for cape Mario, or !19 3 for fire Mario.
If the player needs star invincibility for some reason, load the "starman" ASM with !load starman.
If the screen is dark for some reason unrelated to the disco spotlight in Bowser's castle (e.g. if the "darkness" ASM is unloaded at the wrong time), try pasting !dae f. This might fix it.
Some of the addresses below were copied from a couple of the SMW RAM maps on smwcentral.net, and the rest were directly copied from the credited users while a stream was happening. The "✓" column means that I have tested the address personally or know that it works (fairly) consistently. At the moment there are no untested addresses, but if one gets added later without this check, this may be because the effect I associate with it may rely on some external ASM that was already loaded, have other requirements for working, or be caused by some other value changes that I didn't catch.
The following list was manually converted from a messy Google Keep document into Google Sites because I needed more features and less page load time, and subsequently reformatted to here through some semi-automated processes. I don't remember why I put some of this stuff in the original Keep document, but I copied it all into here anyway.| Start Address | Name ⇳ | Description ⇳ | Type ⇳ | Example ⇳ | Credited User ⇳ | SMWC Link ⇳ | ✓ ⇳ |
