ROM Hack Suggestion Patch for Octopath Traveler Prologue Demo to remove 3 hour lock?

[Falo]

Possible you could make an IPS patch or similar other can apply to test? Without messing in ida

You don't need IDA Pro to use this...

- Dump exefs, extract main from it.
- use nx2elf.exe to convert main to main.elf
- apply patch via hex editor or ips patch
- use elf2nso.exe to convert main.elf to main_patched.nso
- copy main_patched.nso to sd:\atmosphere\titles\010096000B3EA000\exefs\main

a pure IPS patch is not possible, because NSO files are compressed with LZ4, you need to use nx2elf.exe & elf2nso.exe!

here another patch:
.text:000000000008FC94 IsTrialEdition

Change Trial to Full Version:
0x1910C:
change
E0 03 00 32 //MOV W0, #1
to
00 00 80 52 //MOV W0, #0

i will test this later if it works, i first need to play the demo ^^

nice! whats a good way to get dump to work with? install octopath to nand, then dump the nand and use hacdiskmount?

So how do we get the exefs dumped from the digital game?

 

[Falo]

I made myself a NAX0 sd card decrypter to dump games directly from sd card, but it's way more complicated and needs some console unique keys, so nothing for the end user...

The easiest way to do this currently:
- download game to nand
- dump nand
- search in user partition for:
460c01a0e2c8f9711f7f45bcb8db7e4a.nca -> Meta.nca
f5983d8f4951458e8f1413be7579e3f9.nca -> Program.nca
3d0da87dfacc0b00289459aab1e15bda.nca -> Control.nca
bcbc3b14c92a22966b773c2bb42dd39b.nca -> LegalInformation.nca
- dump titlekey from system partition (search for a tutorial)
- use nca tool to decrypt Program.nca to exefs/romfs

I'm about to dump some keys (https://gbatemp.net/threads/how-to-...ool-xci-decrypting.506978/page-2#post-8043284) if you'd care to share the tool?

All working here, thanks for the instructions.

I kinda wish I can understand the reason for including a timer when the game isn't even complete. It's a demo, a closed portion of the full game, why need a timer in the first place? How much sense does it make?

I was gonna try the demo to see the improvements compared to last year's beta prototype but now it makes me less willing to do so. Demos on nintendo consoles are getting worst with every new game, and time limited ones are the worst in my opinion.

Because the demo have a lot of content you can play at least 12 o 15 hours only with the content of the demo. The demo himself is not limited, is limited by the save file to 3 hours but you can make a new game and play again.

Since the save is transferable, maybe they didn't want you to grind too much and spoil the start of the full game.

The main.nso from the demo is almost the same as the full game, technically this is the full version.
Some stuff is of course missing, the full game is 3,1 GB, this demo is 1,7 GB.

anyone attempted save editing yet?

sorry for being a total noob, i have my nand dump, what software do i need to search/extract the user partition?

Which of the patches did you use?

 

[xXDungeon_CrawlerXx]

Which of the patches did you use?

use both

 

[DocKlokMan]

use both

Did you test it and found it required both or did you just put both in first try?

 

[jakibaki]

I only patched the CheckTrialTimeOver-check and that worked on its own!

EDIT: Sorry, I was wrong, I didn't check properly. Both patches are needed.

Awesome!

Wait a minute... did we just turn a trial into a full game, which isn't even officially released yet? That is unreal!

No, this trial is 1/3's of the full game size and only has content to the end of chapter 1.
