Alright I'll just post some of the most problematic issues for now. Most I will screenshot but some I will just describe. I will not bother with tile placement errors, enemy placement errors, or places where the player can get stuck (both due to bad map design on Hudsons part and due to bugs present in the NES version of the game) for now.

Upside down pipes are graphically glitched on rim of the opening of the pipe. You are probably well aware of this already.




This balance lift will glitch.





This flag will glitch. It is caused by having inviable coin blocks so close to the pole. They also allow Mario to jump over the flag run further right and then die.




Mario can jump through this wall. It is a bug caused by having the invisible coin block right next to the wall.




Two objects from a block may not occupy the same screen. One will disappear if both are activated at the same time. In 3-2 it's a mushroom/flower x2. In 4-1 it's a vine and mushroom/flower.



This balance lift has a color glitch and the left pulley is glitched.




This is as far into the game as I can go. The map will no longer scroll past this pipe. Going into the pipe sends you to the cloud world without the vine filling the hole. Dropping through that hole or walking to the end of the cloud world will drop you back to the proper cloud world drop point.

I'll post more as I see them in future patches.

I'm glad that it's you guys that are doing the port tho. It sounds like others may of not taken the port as seriously, not to mention it requires alot more than a level editor to successfully make this.

More flaws for you guys to correct:

The last part of World 2-3 (the goal), the dark area, is supposed to play the ground-level music (as usual), despite the graphics there looking like underground. Looks like there's more code you should do in your expansion to meet this demand.

Also: In the coin bonus rooms in Worlds 1-4 and 2-2, Mario is supposed to drop down from the top. Additionally, when he exits the coin bonus room of 2-2, he is supposed to emerge from the topmost pipe upon returning to the water level.

The bonus pipe in World 4-3's sky bonus (underground graphics)... I cannot go down it.

re: music.. not really a priority in any way

pipes in castle levels always make you come out of other pipes in the smb engine. could be changed but it's useful in 4-4 and not a big deal.  in 2-2, sideways pipes also make you come out of pipes instead of falling from the top.  trivial from a gameplay aspect

the pipes should be lower.. not sure why they aren't.  is that image from the world 5 rom or the expanded rom?  if from the expanded Karatorian you put the updated pipe code in (the one with the one bug removed) right?

 fixed the one pipe in the middle which should not be enterable

Download Worlds 5 and 6

will put out an updated worlds 1-4 soon

When I use the expanded ROM, all I get is a screwed-up title screen when I re-patch (I think I'm supposed to get an already-expanded SMB ROM and then patch the smbspecial_world6.IPS onto it). What do I do?

Apparently, so did I...
