NTSC games on PAL N64 rolling video / shifted colours fix

for more info: Video Interface@64brew
special greetings to Roadhouse of High Society

Now... no need for paladin (& sound issues see threadmark, please download latest version) or a RGB mod... do this:
Hex edit the rom, search for 00000C150C150C15 & replace all instances with 00170C690C6F0C6D
Usually this is enough, but on some tvs you also need to do this:
search for 03E5223900 replace with 04541E3A00
key word "some TVs". as such, my personal pattern, "opt" does not automatically patch this; nor the pal2ntsc reverse ones,
Remember to fix CRC or the game will not boot. (I use rn64crc2)
If the game's compressed (ex. no pattern found) or you aren't using a copier / flashcard, you can easily create a GameShark code.
Dump the ram & search for the aforementioned values. As an example, here's the code that I made for Densha De Go. It is pretty long, since patching only a few video tables just crashed the output (tv: no video but could hear the audio)

Note: Why continuous write? Well, If I remember correctly the injector does not support F1 (write once at boot) cheat codes.
Everdrive does... but everdrive also needs "enable codes". Here's a simplified version of the code, for use with an everdrive.
F105BD20 2400 ---> enable code, thanks Shogun of gamehacking.org
F1074306 0C4D --| only video table used
F1074308 0C4D --| htotal patch taken from n64opt.json
F107430A 0C4D --| and uses F1 write once instead of 81 continuous

Anyway... the long code is below.

#HSYNC_END

I attached a json file in order to automate the process with Garey27's Binary-AutoPatcher (you can find it on GitHub) - Big Endian (z64) input file

edit: added pal game to ntsc patterns zip for ntsc console users that have the opposite problem.
hint: if you're trying to make a pal2ntsc code/manual hex edit... search also for 00150C690C6F0C6E to patch, not only 0017...0C6D!
edit: added optimized ntsc2pal pattern zip
edit: added opt&n64 files in single zip, like the one for NTSC consoles. now includes audio fix by @LaminGaming - see threadmark for RAM patching.
edit: while the method works with most TVs, there are a few in which this fix will not be effective.

are you sure? just tried right now and the video gets successfully fixed (tried with opt.json)... it's 100% the retail NTSC rom since fox gets listed under "Star Fox" instead of the PAL name. Or maybe you were referring to the japanese one?

Yeah, it didn't work for me, not sure how it's working for you, unless I did something wrong. There's only one video table in the ROM, but patching it does nothing, it stays at 61.02Hz.

For Whatever Reason, the PAL60 Patch Requires the NTSC Rom in Order for It to Work, which Seems to be Causing Those Issues. Either That, or the PAL60 Patch was Created with the European ROM in Mind, and Not the Australian ROM (Though idk if That'd be of Any Significance)

I Decided to Patch the PAL60 Version and NTSC Version with Both the Opt and N64 Json Files, as Well as Run Those ROMs through RN64CRC (Just In Case the Checksum Might've been the Issue), and All of Them Still Have the Distorted Video. Here's a Pic of What It Looks Like for Me. It Just Looks Really Bloodshot and Distorted af. I Also Decided to Test the European and Australian ROMs to See if it was a Hardware Issue of Sorts, and Nope. Those Display Just Fine (As Seen in the 2nd Pic)


Unnfortunately, Only the NTSC Rom is Patchable, since Patching the EU or AU Rom will Cause it to Stay on a Black Screen, which Also Explains Why It Doesn't Allow You to Patch Them On Their Website (3rd and 4th Pic)

But Yeah, I'll See What I Can Do with Locating the Values in P64

Just checked the code addresses for the "NTSC" version of Smash Remix and they are the same. I also ran the ROM on my everdrive and had no issues, so the codes are definitely working.

@LaminGaming I'll add to the thread that the fix doesn't work with all TVs. Oh well :(, at least it fixes a lot of 'em.
Click to expand...
Yep! It was the TV!
Tested It Out on a Sony Bravia KDL-40CX520 40", and The Video and Audio are Flawless with the Patch!
Thank You Very Much for Your Help! Really Appreciate It! 🩵🧡
