ROM Hack Resident Evil Revelations 1 & 2 Research

[rdavis0688]

BOLDED REMINDER IN ALL CAPS TO NOT GO ONLINE WITH THESE GUNS. EVEN PLAYING WITH FRIENDS, THOUGH THAT'S LESS OF A RISK. OR MAKE THE GUNS SEEM LESS POWERFUL I DON'T KNOW WHAT PARAMETERS ARE FOR BEING BANNED.

Hello folks,

Seeing as I don't see anything about editing saves for Revelations 1/2, I'm going to do some looking into it. Expect small bursts of activity, and you'll be able to use Checkpoint + HxD to do your editing, or will have to as @Aroc to make a more fancy editor if he so pleases. We've found enough about Hyrule Warriors that other people can pick up that torch and I want to mess around with raid mode after I got my orange name (see below) and the weapons I wanted from Ghost Ship Chaos. For now I'm likely to be looking at giving myself more of the GSC rewards because they're so boring to get, and when I find the offsets I'll put them here. If I can figure out weapon IDs and power and all that stuff, I'll paste it here as well. Or I'll make a pastebin that has all the offsets. I don't really want to grind til I'm dead in Revelations 2, so I'll probably start with seeing if I can modify weapons, character exp, skill points, etc.


Game is Little Endian

Hex Block for BP:
0001 415A - 415C

-- Lana

Red is different, green is matching, blue is new. I originally thought that the game was sorting the file differently every save, but that wasn't the case, leaving this here for posterity.

The sets are always lead up to with 80 00 00 00 80 01 00 00 00 and afterwards. So the full code for Damage 1 would be: 80 00 00 00 80 01 00 00 00 63 00 01 00 07 80 00 00 00 80 01 00 00 00

The way parts are laid out are as follows:

01    02   03  04  05

|    |    |    |    |

|    |    |    |   - Mandatory Space, used in weapon building (see below)

|    |    |    ----- ID

|    |    ---------- ID

|    --------------- Blank

-------------------- Count

Range for adding Parts: Seems to be 0000EC1D-0000F8D8ish. Plenty of room to add what
you're missing.

What appears to be weapon damage.  3D is what GSC 50s have, so just use that.  If you need a lower level weapon it goes from 01 to 3D.  Have fun.



So with the explanation of the first two rows out of the way, I'll give the full template for a weapon:

00 80 11 11 05 80 00 00     00 80 01 00 00 00 00 00

                                Blocked Slot



The above is a random legendary gun with 6 slots, 10 points in fp, cap, and fs.   I used 06 for slots so I can show how to block off a slot should you so choose.

Example of a Grim Reaper +765 (Legendary Pale Rider) with 7 slots, and those slots being filled for @Aroc ,

You use the last three hex values of the weapon part above to attach it to a weapon.

This gun will have Damage 6 (00 01 07), Rare Finder 1/2/3, BSAA 2, FBC 2, and STARS 2.

08 80 20 11 05 80 00 00   00 80 01 00 00 00 00 00

08 80 20 30 07 80 00 00  00 80 10 30 07 80 00 00



So if a part value is 63 00 (which is just the count and a spacer) 01 31 07, the  01 31 07 is what you would use in adding it to a weapon.  Thanks for your work on the editor.

Probably 0C or higher where it can't find a value would work? Dunno, not into trying tonight, er this morning.)

Since I got quite a lot of data for Rev1, at least what I can since I can't find XP, and there's really not more to it, I'm gonna start in on Rev2. So far I'm gaining XP to check against a starting out save, hopefully I can find XP values to start.

Got some values I can work with and hopefully manipulate so I can start farming stuff. I'm gonna need a loooot of parts, I heard there's more in this game. And guns. Lots and lots of guns.

So I've found Gold, Character Levels, Character Details (including SP), haven't started on guns for one main reason - changing anything inside of the save gives me an error such as "corrupted save data". Even changing gold. So I have to find out what's going on.

Turns out I'd need a physical cart to dump the game data so I could go through it. I can't do it right now. There's an internal checksum that is compared against the values in the save file. So, without a physical cart and a way to get the data I'm stuck at present. They went out of their way for save protection for rev2 but not rev1. If I have spare cash to toss around I'll get a cartridge.

 

[rdavis0688]

Reserved for Rev2 for when I get around to it.

 

[TrunksSSJ23]

Great work! Looking forward to the updates.

 

[rdavis0688]

Glad that someone could use them.

 

[Getzabelz]

I'm afraid this is overcomplicated for me, is there any chance you release a game save file with the game from beggining with cool stuff or something?

I would like to play it but with some ammo or weapons hehe.

 

[rdavis0688]

Not right now, sorry. Hex editing is not that complicated if you follow a primer on it, and then follow the instructions above. Right now I'm too busy working on finding the values for things, I haven't even got to building saves and such. Plus there's some other stuff I want to do for kicks, like bring over SP parts and weapons if possible (like the inf. rocket launcher for the hell of it.) I would recommend learning how to hex edit as that's going to be the way a lot of things are done. I'm not gonna make a fancy GUI to do this for people, I'm just finding values so someone ambitious can make an editor if there's enough interest to do so.

Sorry if that's not what you wanted to hear, but if you're going to be modding things you *really* should learn a little bit about hex editing and backing up saves with checkpoint and such. It'll come in handy in more places than just here. Not every game will have an editor, not every game will have values out there, so learning how to compare things is important.

 

[rdavis0688]

Empty post I don't know how to delete.

 

[rdavis0688]

Again, Empty. This is not the hex you're looking for.

 

[Entoptical]

Interesting thing to note, the game seems to restructure the file depending on what mode you were last in? I'm not entirely sure but you can see it really clearly in my safety save and my save where I changed my BP and sold 1 of everything to differ it from another save:

View attachment 135364

Red is different, green is matching, blue is new. So, I'm not sure if something changed when going from SP to Raid, but it does mean that I'll only have to look in a few key places where things are identical to start, and try to find where all attachments are, guns you have and their upgrades, and other stuff like that. I'd probably take a while to find all the gun types but if they look like they're ascending in IDs it would be easy to make a gun. I'll post again when I have more info, sorry I don't have a big update, just surprised about how different the file looked. Honestly it makes me think that the only matching parts are important. We'll see.

What app is used for the visualization?

 

[rdavis0688]

What app is used for the visualization?

Flexhex. Though it turns out it was just FlexHex displaying things oddly. The file structure is static every use after. Though I've switched to VBinDiff. It's dos-like (since nothing really runs on dos, it's a windows console program) as it allows me to line up files side by side more easily and see unique differences instead of blocks.

A bit more complicated than HxD or Flexhex, but then, I've found quite a bit by using it (see parts list.)

 

[rdavis0688]

Cleaned up posts.

 

[Entoptical]

Can't wait for memory editing cheat code capabilities. Scraping gamesaves is brutal

 

[rdavis0688]

Yes. Yes it is. I'm about done for the night, I just can't take making yet *another* save file to compare things to. So I'm playing some code veronica, then back to the mad engineering.

 

[rdavis0688]

Reserved for Rev2 at some point.

 

[rdavis0688]

Merged with main weapon post.

 

[rdavis0688]

Revelations 2 has a checksum system built into the save. If I change a value without regenerating the checksum, it'll say the save is corrupted. I have to figure out how to regenerate that before I can go any further, this may be out of my hands for a bit. But I'm a decent learner and programmer, so I should be able to figure it out. I like challenges. Just Rev2 is gonna take a while.
