I need one for a.mappack for a remake of UnderJump.
List of known editors that don't work:
SMB Utility (including the nodded version)
YY-ME (this one kinda works, but can't load the bonus rooms.)
Anyone know of a good SMB level editor for Windows that can load up Super Mario Bros UnderJump?
I think the romhack may be using some custom assembly, in which case editors would have issues locating level data as they usually look at specific offsets in the ROM. In which case, your best bet would be to play through the game in the emulator, making screenshots along the way and then making pack based on that data.
Just use SMB Utility, one of your only hopes out there.
GreatED is also a recent alternative that adds new objects and enemies (which results in the saved ROM expanded).

Oh right, I forgotten that this hack in particular has gone through ISD SMB Utility, that expands the final ROM into 81KBs after some .bats and mapper patching; GreatEd doesn't load such a hack from my testings and thus you might need to port the levels via SMB Map Importer (https://cdn.discordapp.com/attachments/ ... rter_1.exe)
into the original SMB1 ROM, which this ROM will be readable by ISD SMB Utility (do note that this "editor" only lists down SMB2J items within the program, you may need to double click on each independent block to reveal what the object actually is in the 81KB ROM).
The ROM address where 1-1 is loaded is around $1F00 and so on; I am not sure whether ISD SMB Utility has the values changed, and if so, by how much to an extent.
