Potentially Useful BTS Blocks For Hacks

Researched by Aran;Jaeger


This is a list of several existing BTS variations of blocks in Super Metroid which could be used in hacks for many different purposes. In order to understand this list you must have a basic understanding of counting in hexadecimal. Visit this page for more general hex editing information, although it should be noted that using these blocks does not require any direct hex editing.

Note that the properties of certain blocks are room-dependent and in some cases also position-dependent in relation to the room. Some blocks also have unstable/inconsistent behavior. There are other block values for blocks within this list that have the same properties and thus are not listed in here.

If you find any other interesting BTS blocks, feel free to add them to this list.

Formatting Rundown

In order to understand this list, you must understand the basic format in which it is written. An entry in the list is formatted as follows:



  • XX = the ID of the type of block
  • YY = the BTS value of the block

So, if I wanted the effects of the following block:

  • 02(65) “graphic patch” respawn-treadmill-bombcancel-block

I would place an Air Fool X-ray block (which has an ID of 02) with a BTS of 65 in SMILE.
