Healy blocks This patch creates a block that is shared across all of the tilesets in Metroid that when applied to a structure, heals Samus on contact by about 6 energy per second. To change which block in the structure editor is used, first find what the bit of the block is in the structure editor by clicking on it, then find the CMP command within asm file that is commented with ;healyblock? and change that value to the blocks bit you found earlier. To assemble the .asm into an .ips, use https://dl.dropbox.com/u/12027218/snarfblasm.exe. To use this, simply drop it in the same folder as the assembly, and then open a command prompt and navigate to that folder. Then enter snarlblasm . This will create an IPS for you that can be patched directly onto a (U) Metroid ROM. These intructions are essentially the same for the other 2 patches, and therefore I will not repeat them, other than to tell you where to edit for the other patch. NOTE: The separate Healing Block and Damaging Blocks are not compatible. If you wish to use both, use or edit the combined blocks patch. ---------- Damaging blocks This patch creates a block in the Structure Editor that, when placed on a structure, does 6 damage per second. An example of a use for this would be a superheated room, or a room with a similar environmental hazard. To edit which block is used in the structure editor, follow the instructions in the above paragraph in asm file, however, instead you must edit the CMP command at the line commented ;hurtyblock? with the bit value of the block you chose in Editroid. ---------- Combined blocks This patch makes blocks in the same places as each of the separate block patches, however, it handles the data in a way that makes the two compatible. To edit the blocks used, simply edit the relevant values mentioned above in asm file.
