Instead of continuing my necropost 😶, I will make a new thread. So, I have been looking through the source of the game, and so far, here are my discoveries. Firstly, and most importantly, the levelmap. In main.c, there is a level map, that is currently

Code:

Now that we have an editable map, we need to figure out what each number means. Looking through the source again, there are 6 images, wall followed by 0-5, as a png. There are a couple of sprites here that you see in the game, like the spider sprite, 2 (?) walls, and some other walls, like the ladder wall which is the win condition. TheLastMillennial suggested that the codes would be
"0 - floor
1 - wall
2 - radiation
3 - unknown
4 - escape ladder
5 - health "
So, to check, i decided to make a test map for the game, the maps gonna look like this

Code:

I ran it, aaaaaaand it just showed the default map from the original game :/ Will be testing more...

If you look at the features.py and main.c (line 717 is the most helpful) files in the original source, you can see that if you subtract 1 from each, they match up with the corresponding wall*.png files in the source directory. So TLM is correct:
0: blank
1: wall texture 1
2: radioactive
3: wall texture 2
4: ladder
5: health
6: wall5.png is the spider, not included in the map though

It would take pretty minimal effort to make an editor for this and modify the original source to accept a custom map from an appvar, but I'd talk to patrickdavidson to make sure he's fine with you messing around with it.

I tried making that custom level, but when i built it it just ran the exact same level that is in the original game (no clue why). I have been looking through the ASM and all the other files looking if there is in fact another levelmap, but no luck thus far :| ...


i couldve just built it wrong @_@

Yep, you probably built it wrong. Make sure everything is saved and you delete the old declaration and try it again.

Update: Tried to build it with CEdev, and after a lot of fiddling with the makefile, it asked for a certain palette.h, which i don't have. Does anyone know of this pallette.h? it doesnt seem to be in the source for the game...

Another update, I tried building it, this time it didnt even give me a .8xp file! (this is gonna take a while)

update: Running the headers.py finally gave me a pallette.h!!! yippe!!

update 3: currently, I am playing wack-a-mole with the variables, as after running the python, the variables went everywhere so I have to make EVERYTHING
Code:
. This might be my last update for a while, I might take a break from this...
