FireRed Dive
Download and fully extract the .zip file attached to this post.
Load firered_dive.asm in your text editor of choice and follow its instructions.
The attached download simply contains the file firered_dive.asm (found in the spoiler below and at https://pastebin.com/raw/1yjWuuuz), Lunar IPS, and base.gba (simply a 0xFFFFFF-sized file of just 0xFF bytes -- the .gba extension is just for simplicity's sake as it will mean Lunar IPS lists it by default).
