[SM] Changing Routines

[Odylg]

A while back I posted an issue I was having with item collecting.
I had done some hex edits to remove the message boxes for picking up items while leaving save stations alone.
I found that if I grab an item, such as the missile in 7A107, and leave the room relatively quickly I would get temporarily stuck after the door transition, waiting for it to fade in. I tried changing the music in SMILE for each pickup. No "Item Get!" fanfare, delay still there. I was told the issue was with the message box routine still being active.
How do I make sure the rest of the routine doesn't stay active?
I was directed to
http://jathys.zophar.net/supermetroid/kejardon/messageboxes.txt
but I don't really understand it.
At least with hex editing i'm given the original bytes (or at least how many) and what to change them to, like:

$208EB  |  22 80 80 85 to EA EA EA EA

Simple enough. But then I look at something like this:

   JSR $8143  ;  $28143 IN ROM. Layer 3 message box setup?
   JSR $81F3  ;  $281F3 IN ROM. Layer 3 clearing above and below message box
   JSR $8241  ;  $28241 IN ROM. Two subroutines depending on $1C1F. I'm guessing tiles and length, in that order.
   JSR $8574  ;  $28574 IN ROM. Adds a 2 frame delay, if I understand this right.
   JSR $844C  ;  $2844C IN ROM. 'Opens' the message box. This takes up several frames, during which nothing else runs.
   LDA $1C1F

   JSR $846D  ;  $2846D IN ROM. Code for while message box is open. Nothing else happens during this. (Wait for X time than any button usually, or wait for A or left/right/select on save)

   JSR $81F3  ;  $281F3 IN ROM. Layer 3 clearing, again
   JSR $861A  ;  $2861A IN ROM. Layer 3 message box cleanup.
   JSL $82BE2F  ;  $13E2F IN ROM. Resume speed boost and charge beam sounds, if necessary, and a few other sounds I'm unsure of.
   JSR $8574  ;  $28574 IN ROM. Another 2 frame pause.
   JSR $80FA  ;  $280FA IN ROM. If map station, go to pause screen. Else if 1C (ship save?) or 17 (save station save), LDA $05F9 (selected option)

and I have no idea what to do.
Any help would be very much appreciated.

The thing you posted is assembler code, normally having .asm extension.  Just edit the assembler code in a text editor to your liking, then apply it to your ROM using an assember such as xkas (xkas = cross-knight assembler).  The assembler creates the actual hex codes itself from the asm commands.

To apply a patch in xkas:

Code Select Expand

xkas patch.asm game.smc

Then just find asm patches that are simple enough to tweak to your liking:

Nvm about what i just said about the hex edit. I forgot id posted the message box.txt.  Unfortunately, even though the message box doesn't show there's still a part of the routine running, causing a delay in room transition. So I do need ASM but I dunno how to make it for I am noob.

EDIT: I tried turning the txt file I posted into  ASM.  When applied I can't get past the Nintendo logo. Filenames are the same. I'm using unheadered, could that be why? Or is there something I'm supposed to tweak in the asm first?

Still no, sadly. Takes just as long as the video showed. Had it and a fresh ROM both named RoutineTest, dragged the ASM and dropped it onto xkas. This was an unheadered ROM of course. Also tried a fresh headered one and the game freezes going down the first elevator
