My game crashes when I get into the Radscorpion caves just before or after I kill a 2nd Radscorpion. I am getting an error that reads
The instruction at 00418fe7 referenced memory at 490b4923
The memory could not be read from
How am I able to rectify this error?

Thanks. That may be a possibility. I actually saw something about the ddraw file and renaming it. I am gonna try that first.

Well if the ddraw fix doesn't work you could also try the high res mod. Thats what fixed some problems on my win7 machine with this game. Not to mention playing in a slightly higher resolution is pretty cool.

I actually just downloaded the high res mod. I also renamed the ddraw file too. Do you know how you are supposed to change the screen size so it is not really small? However I have not played yet since I DLed the other mods to see if it has completely fixed. after I changed the ddraw file some of the pixels were all rainbowed but after adding some of the mods it seems to have been fixed and looks normal except the fact it's so small from the resolution. I think I need to put it to 400x800 but i do not know how to do that.
I have vista by the by.

Load the game up and go into options. Along the top is a button called scrn. If you click that it will take you to the resolution options. You will want to choose a resolution in the middle to lower end. Something that zooms it out a little and makes it look nice but so you can also still see whats going on. I played on 800x600 to get it closer to the original but so it also looked a little more cleaned up. I reckon 1024x768 isn't to bad as well but much higher and everyones tiny. Also make sure to stick it on 16bit colours.

I can not find the options on the screen for Fallout 1.
I found where I needed to change it tough. it was the res_ini. file.
Do you know how you stop the rainbowed pixelation prob? or is that a reason to change it to 16bit?
Do you know how to make the pipboy screen, chat/barter screen and the bottom hud bigger to fit the screen?

I actually think you may need team x's patch before you apply the high res mod just to get the game to the US version as the gog version is UK I believe. That might be why your not seeing the option button on the start screen. Then yea you will want 16 bit colour as well but you shouldn't be getting rainbow pixelation in 8bit anyway it will just look worse.

Has the high res mod and instructions on what versions it works with.
The teamx 1.2 patch is here

If you install that first and then the high res mod over the top next time you go into the game it should have an options menu with that scrn button at the top as well as a ton of other options.
Edit: I can't link directly to the patch as its running through a translator but you want to go to the files button, then patches and then grab the fallout v 1.2 semi official one.

I did that when I did those mods before adding High res mod. So I do not know why I do not have the option option, lqtm.
Do you know how to make the pipboy screen, chat/barter screen and the bottom hud bigger to fit the screen?

I have no idea why your options thing isn't showing up then. You were able to edit the config files though and get the disired resolution and set it to 16bit colours? Are you still getting rainbow effects?
I also couldn't find anything that would increase hud and writing size and not through lack of trying. Thats why I advised earlier to use a resolution like 800x600 or 1024x768 something on the lower end so it looks better then it did but you can still read and see what your doing.

I still get them but it's random. If the game starts and it shows that I can just restart the whole thing and it can be fine.
I am doing it on 800x600 though and it's good, just the pipboy, chat/barter screens(shows a bit of black around it for it being slightly to small) and the hud is slightly to small still. It started me on 1024x768 and everything was too small for my tastes.
Definitely thanks with all your help so far!

Have you gone back to the rad scorpian cave to see if that works yet?

I did. I also reinstalled and remodded. Somehow when I added the children mod they didn't get into the game but they are now. lqtm. I was in there for a while before it crashed but I had left ddraw alone. I just renamed and did the same with falloutw.exe so it has no "w". It seems to be ok now, went in a couple of times, but only time will tell...lqtm.
Thank you for the help you gave.

No problem, hopefully its all good now and you can get to playing this game rather then fixing it.
