This is a reconstruction of the infamous vector logo intro by Paranoimia on the Commodore Amiga. Uncredited in the intro were the coder Pwy and TSM of Sunriders, who created the music, which was assumably ripped from somewhere else.
This disassembly was created with ReSource V6.06 directly in Commodore Amiga emulation and then tidied up a bit in ASM-One.
On an Amiga (or emulator), run the ASM-One or Asm-Pro assembler and load the source file with the "r" command. Following that, assemble with "a" and run the intro with "j main", which jumps to the main entry point of the code.
There are many things that could be optimized in the code, but it was probably intended for Amiga 500 machines. Code and data are scattered through memory, probably by using EXTERN directives with absolute addresses and also equates for memory buffers that are also absolute.
If you want to change the vector logo you need to adjust the number of points and lines equates at the beginning of the file and change the values in the points_x, points_y and line_table tables.
The music code was disassembled as-is and works. There is a release of the music's executable that includes assembler symbols, but I concentrated on the graphics code and did no commenting on the music code.
