While this might be too early, I got inspired by the SMT IV Editor to start checking out the save editing for this game.

I was able to edit skills and stats so far for the MC and the Demons but since there's so many skills to check (not to mention the enemy-only skills which I would love to have) so I might as well start things so a save editor would soon follow for this game.

Some skill digits I found out so far.

7900 (79) - charge

c501 (1c5) - victory cry

e801 (1e8) - phys pierce

af01 (1af) - phys pleroma

b001 (1b0) - phys gigapleroma

6f00 (6f) - silent prayer

5901 (159) - soul drain

8801 (188) - andalucia

ee01 (1ee) - awakening

8400 (84) - smile charge

6800 (68) - luster candy

5700 (57) - salvation

c200 (c2) - desperate hit

b800 (b8) - riot gun

6b01 (16b) - akasha arts

For stats, the normal maximum is 999 but I don't know yet if you can push it even higher.

Well I was able to make huge progress on it lately after asking other japanese players.

There's a complete skill digit list now, along with item digits for everything and stat editing for your party stock (the compendium editing is still tricky). You can use my safe file as a reference point.
 

Something whatever

The list needs to be cleaned up for the US version though since it's mainly google translated.

I'll upload other lists later on.

I'll go through and fix the translations assuming no one gets to it first. Looking forward to the other lists

Rough item data (first set of addresses is the hex placement, just ignore the "1". second is the quantity on the current hex digit).

I'll be uploading my save file as a reference point soon.

Any chance we can get that Demon list first before your save file? Someone mentioned the possibility of using the DLC characters like The Hero and Aleph in demon slots

Unfortunately, the demon digit list is the only thing that wasn't checked out.

Here's my save data in case those who might want to find the demon digits via stock or compendium.

Could someone explain how you'd do this with hex or be willing to edit a save for me? (I'd just want max money & a few items). Only ever used Editors never raw hex changing.

Why is it that it doesn't exist when you'd think that would be the first thing people would want?

WIP for Item Editing (done by modifying the save data file):

Item Editor:
1. Find hex string "CBFFFFFF9F" (assumed offset is 0x00003DFB ~ 0x00003DFF)
2. If address matches... find the offset accordingly for the item of interest, where a modification of the data string represents the quantity of the item (Hex value of 63 = Decimal value of 99 [the actual quantity in-game]):

0x00002F62 = Summon Stone

If anyone is still looking, I made a simple SMT IV Apocalypse Save Editor here: https://github.com/waynelimt/SMT_IV_Apocalypse_Save_Editor

Awesome save editor, I'd just like to point out that you're missing some skills, so if possible, see if you can add those in as well.

Also, I noticed that there are some inconsistencies regarding skill affinities, for example, let's say I have Surt who has +7 fire skill affinity, if I use the editor to replace a fire skill he had with say, a physical skill and reload the save, that physical skill would have +7 affinity instead of +4 which is what it should have, can you find a fix for this?

    From what people say pvp isn't even worth it
  • BigOnYa @ BigOnYa:
    I just been playing offline, and they give you a few bots here n there on your team to help battle. I don't think it's as funny as the other games tho, more battle oriented than humor, which kinda sucks, but I'm still early in it
  • Xdqwerty @ Xdqwerty:
    @BigOnYa, doesnt the game have a campaign mode?
  • BigOnYa @ BigOnYa:
    Yea, and co-op, but you can also start a pvp session and battle just with friends. You get special skill cards (powers) the more you play. And higher value cards, but you can only enable so many cards at a time.

    Toilet paper is considered the money, you collect and buy stuff with TP, kinda funny. Graphics are def better than the other games tho, I think they used Unity 5 engine.

    For example, a 21-inch (diagonal) GE color television in 1965 had an advertised price of $499, which is equal to $4,724 in today's dollars, according to the federal government's inflation calculator.
