What's the maximum allowed size for M_DOOM?

[Amaruψ]

I'm currently on the stage of creating main menu graphics for my .wad, and I've run into a small problem. I don't know what's the maximum allowed size for M_DOOM. Now, I'm well aware of 125x60 being the default size, but I want to create one larger than that. I tried to create a test graphic sized 256x64 (to calm my OCD of not having proper values like that), and this was a the result:

 

 

It seems to be offset from the center for some reason. I looked at Rowdy Rudy 2, and there the M_DOOM was sized 218x35. I tried that size, but once again, for whatever reason, it vertically sticks to the top of the screen and horizontally refuses to center. I'm not sure what I'm doing wrong here exactly, so any help would be appreciated :)

Haven't looked into the maximum size for M_DOOM, but you can adjust the position of the image in-game by changing its offsets in Slade, just like you would adjust sprite offsets. This is something you usually have to do whenever your images are larger/smaller than their vanilla counterparts.

Oh lordie, this didn't cross my mind at all.

I'll give it a shot then. Thanks a lot :)
