Broken seed: R220-QE6M-Z1F50C7

During Leon A, you suddenly change to Ada on the way to use the chess plugs, and because you can't change back, it's basically a dead run.

Unfortunately it always crashes for me when I get a room with four or five giant moths

Sorry I don't have the seeds any more, but it was 3 different rooms in 3 different seeds, versions 1.2.0 and 1.2.1. Didn't have a problem with the last seed I played which was R220-9P38-Z1RHG7E with version 1.2.2. I'll make note if it happens again.

Also with seed R220-9P38-Z1RHG7E I didn't get a second weapon. Feels like more often than not I'm at the final boss and I'm stuck with the handgun.

This is awesome! If you set ammo to max drops, and everything else to 2nd lowest level, it makes a totally new mode to play! I'm for sure calling it scavenger mode, and will be making a ton of videos.

Youtu.be here's the first one and it's tough as nails. Also good for anyone who needs an example of what it does!

Another issue, with seed "R221-X1Q5-Z1UN3N9" Sherry appears before the alligator fight with Claire. As soon as the fight starts, she is lying down for some reason like she's dead and I can't leave through either door.

Great mod. Most of the seeds worked. However I had my first crash with this seed: R221-BV2Z-V1MM4ZZ. It happened when using the C panel key as Leon. Thank you for his awesome mod.

How do you setup your seed. Whenever I load the mod it's just like the original game and nothing is randomized. Thanks.

IntelOrca,

I love your mod so much I carefully did the installation of it yet it didn't give me the rights to load the Randomizer. I tried to solve the problem for days but no goal. Please advise. Thanks.

What I mean is after generating the seed then I start to load the mod but nothing is randomized. It's just like an ordinary Re2 game enemies and items don't change at all. Please help. Thanks.

When you started the game, it brings up the rebirth launcher, once you click okay, it then asks you to select which mod you want to play. You can then select the randomizer. Did it bring up the mod selection for you?

I don't have a choice to select anything because when I click okay the game starts right away without mod selection.

It sounds like it is not generating the files in the right place then. You need to tell biorand what your RE2 installation directory is and then run the executable in that same directory.

I make a short cut of the Re2 exe and put it to the desktop then right click on it and select properties, and copy the text in the "target" box. I then paste the address onto the bottom part of the biorand , then click seed and then generate then play the mod. Is this not right?

It sounds right, but maybe you are running the wrong exe or have a slightly incorrect path. Can you paste the path you are using and the directory structure of your RE2 installation. I assume you also have the rebirth patch? It should bring up a launcher when you run the game where you selection resolution and other settings.

I tried all the means but... I have been thinking, if seed can be generated, the path should be right and there should be a new biorand folder generated in the bio2 directory also. But I don't have it. I don't know why. That's why I am unable to load the randomizer and this is the problem I can't solve.

I am not sure, if it said it generated successfully, it must be somewhere - I can only assume not in the place you are looking.

Nowhere can I locate the new biorand folder. I am thinking, could it be possible that the seed generated is not a real one or an empty one?

try to rename or delete config.ini inside your re2 folder , run the game again.
edit: check your ddraw.dll version , is it 1.0.9.0 ?

edit again : I move [biorand] into folder [biohazard 2 pc] , when I run the randomizer , remember to set the game path , make sure there will a folder name [mod_biorand] in your [bioharz 2 pc] after running the randomizer.

Are you able to do a computer wide search for mod_biorand? A tool like wiztree can scan all your drives very quickly and give you a quick way to search for a file or directory.

I searched drive D yet no mod_biorand found. But I found something else.
I tested a randomized mod which is in drive D called RE2RNE_V25_2. After I created a new seed it said "Done and ready to play:) Remember to choose [DEV]Randomizer in the Mod selector" When I started to play the mod I still didn't have the choice.
I am wondering if there's something wrong with my PC.

check your ddraw.dll version in your RE2 . (v1.0.9.0)
if your version is 1.0.9.0 , then :
move your all re2 folder to other drive to test.

by the way , what's your PC SPECS ? is it windows os ?

ddraw.dll is v1.0.9.0 all the time. I had tried to move the re2 folder to drive D,C and usb also. But the results were all the same.

My PC specs
Desktop
Processor: Intel(R)Core(TM) i7 6700 CPU @3.40GHz
Install Ram: 16.0 GB
Spec: Windows 10 Home
OS build: 19044 2006

Yes, forgot to tell you about that RE2RNE_V25_2 thing. Even though I don't have the chance to choose the [DEV]Randomizer yet when I play the mod the 4 items changed from the new seed like enemies, items, conversations, npcs are still there while the mod_biorand doesn't have that effect.

Sorry, I am really running out of ideas on what to suggest. I don't see how it can show the success message unless it was able to find your RE2 files and generate new files in a mod_biorand. The fact that you can not find those files anywhere on your system is a mystery.

I hope this is not your last way.

You know what I had reinstalled the re2 several times with and without HD mode and put them in different drives. Also I had tried the biorand from 1.00 to 1.2.2. The cr is always new. The results were all the same. That why I thought there might be something wrong with my PC.

There is only one way to test whether my PC has problems or not. My suggestion you might refuse. If you could send me the generated mod_biorand to test. If it doesn't work that means my PC is really has problem. What do you say?

Another unfortunate event: if Irons is the NPC in the sky tram during Leon's scenario, he just continuously walks into you during the cutscene with seemingly no way to escape it.

Also, taking the sky tram has a habit of landing you in the vanilla sequence during a door rando, which then ends up either teleporting you around the game or skipping entire chunks of gameplay.

This has happened twice already, but this seed in particular is R220-RF8R-Z9W50C7.

I think this is caused by certain combinations of Ada and another NPC in the same room. Annoyingly the symptons appear in one of the following rooms, but the problem is actually in the previous room.

I think in this case, having two Adas in the same room, when the cutscene happens causes the Ada model in the following rooms to glitch. So I will probably just exclude Ada as an NPC swap in that room.
