Looking for P4G mod to reveal dungeon maps

[hushed sky]

Hey there, i'm trying to find a way to reveal dungeon floor maps instantly, so i know where the stairs are to rush through them. Is this possible by modding? I couldn't find any yet. Other ways (CE/Trainer) would work too.

Anyone knows of something?

This should do the trick, enable the checkbox before entering a dungeon and it should reveal the entire minimap.

Cool thanks, I’ll try

[hushed sky]

Ok, so i get a weird error when opening the file, but nevertheless, it works! Thank you

So I gotta ask

Would this be possible to make a mod using reverse engineering ghidra instead of relying on cheat engine?

[dusk zodiac]

Pretty sure it’s possible, not sure if I’m the one to do it. I’ve done a lot of stupid things with P4G, but haven’t really touched ghidra during my work, I just work in x86_64 and put my changes in via Reloaded-II.

[dusk zodiac]

Glad to hear it’s working. I get the same message when loading it, so I might look into that later and correct it. Will send an updated table if I figure it out

[leaden current]

okey ill try it soon

[dusk zodiac]

Here's the updated cheat table, error was caused because I didn't know that saving my script would also save all the other stuff I had in cheat engine, resulting in a lot of excess being stored with the script. Too used to treating Cheat Engine like a debugger.

Oh cool

Sweet

Nice, thanks a lot @dusk zodiac

@dusk zodiac

did i do something wrong?

[dusk zodiac]

Was it enabled before entering the dungeon?

[leaden current]

f

[hushed sky]

you have to change floors, then it works

[dusk zodiac]

I set it up so it sets all the tile flags are set to 1 after the reset called between floors

It was either that or cover it when it tries to update, which occurs several times a frame and just sounds wasteful to me

[leaden current]

my bad

hehe

[leaden current]

yup

from 11f to 10f

now on to implementing this in ghidra...

do you happen to know which function address is this?

[dusk zodiac]

Yes, give me a moment

[hushed sky]

btw. is it difficult to add this in another table?

and since it shows treasures, are shadows possible too? Maybe not, because they move?

[dusk zodiac]

Two calls, one for pregenerated floors (ones with minibosses) and one for random floors. Both use a function located at 1402DF000, I intercepted the area after the call at 140311620 and 1403115EE respectively to update the values. Another address of note is 1451EC580, which is a pointer to the area of memory dedicated to holding the revealed minimap data (48 bytes, each bit corresponding to a part of the 16x24 dungeon map). That pointer is initialized very early in the game and remains the same for the duration of a session (afaik, all of my testing has been on the last day)

[dusk zodiac]

Shouldn't be too hard to add to another table, but I don't use cheat engine for this, so I'm not certain.

[dusk zodiac]

Should be possible, not sure how. I imagine the data is stored nearby, but I never bothered because Rise gets a skill that does it for you. Since I'm testing on the last day, I already have that skill and have never needed to figure out the enemy location logic for the minimap.

I see i see thanks for the info

[hushed sky]

true that, thanks 🙂

If you ever have any dungeon-related questions in the future, feel free to sling them at me. I have spent more than a little time messing around with this stuff specifically, I might be able to help.
