Author: Conn
Information: The game will Switch to part 02 after your uncle left the house skipping the whole introduction sequence when you rescue Zelda.
Please note that we speak about Byte terminology (not HM terminology) - this means
- part 00: telepathic message, uncle leaving house
- part 01: uncle gave sword, able to save
- part 02: after Hyrule Castle, now searching Pendants
- part 03: after Aghanim, now searching crystals
Rom: Any ALTTP (US), without Header
ASM:
note:
- if you already adjusted the beginning part with the srm Startup modifier you Need to undo These changes!

- Code:
LDA #$0201 ; 01=part of the game $3C5 - 02=Progress flags $3C6
STA $7003C5,x
- delete these two sentences and run the asm again, the Progress flag will be set to #$10 anyways when getting into part 1, so if you Need another Progress flag you Need further asm!
Also you Need to set $3C8 (starting entrance to 00)
LDA #$0001 ; 01=Map indicator $3c7 - 00=Starting entrance $3C8

After the text file with the asm extension, run the with xkas assembler. This can be a problem, since this is DOS based like zcompress and uses certain commands which you need to type in. You also need a clean rom. Xkas will then compile the ASM into hex values and insert them into the rom.Hey coon question how i use youre codes?

Then you can compare between original and with ASM inserted with the compare function of the hex editor and come up with what to actually do in hex (so you can isert the code in hex anytime without xkas - this is what I always do - I call this hex decoded ASM).
Since you see ASM in hex. For instance LDA #$02 will become something like A9 02 in hex etc.

Note, that the first box of the OP is an asm that can be compiled in xkas, the second box was individual infos for SePH and the 3rd box, gives hex addresses that need to be manually changed using a hex editor.
To use xkas,
- create e.g., part2.txt
- copy the content of the first box into this txt file
- rename it to part2.asm (extension must be asm!)
then make a batch file
- create a text document (xkas.txt)
- rename it to xkas.bat
- adjust and copy this content into it:
run xkas.bat (note that xkas.exe must be in the same folder along with zelda3.smc (be sure your this is the name of your rom or rename either the rom or the bat file line).
rom to patch must be headerless, and in this case not expanded (uses native free space only as far as I can see it)

You're welcome 
It's compatible with any headerless zelda3 rom, also the all-in.

A nice patch, SePH. Thanks for sharing. I'm sure many hackers will find this one helpful.
