The Pa_0 tileset from NSMBU ported to NSMBDS by me, feel free to use it in your hacks, you don't have to credit me for this unless you want download it here #1452097694607872131 message.
All the necessary files are included in the folders from the ZIP below, to replace them, go to the ROM File Browser tab in NSMBe, select the corresponding folder, click "Replace", and select the folder that has the same name than the one you're replacing, this will replace all the modified graphics so that you don't have to import them one by one (you can still replace the files manually, but the method I explained earlier is faster and less tedious).
Also, you'll have to set the tile behaviors of the spikes and vines by yourself, since jyotyu behaviors are stored in overlay 0 and thus they won't change by just replacing the .nmt
