Oh, it's rarely that users do have problems with .nmp and not .xdelta

I can patch with both, it's just that nmp always works and xdelta doesn't always work.

For xdelta you have to be told the /exact same rom/ release.

I'm going to specify precisely the filename you're supposed to get and use the first google result for it.

XDELTA does error out on wrong rom.

So, here's a fun bit of news. I managed to do this: (read description)

That's awesome! Is this limited to music, or could you potentially make this work with tilesets and backgrounds too?

Mero already did.

Oh, nice! So will loading more than 1 tileset per level ever be a thing?

Never with the NSMBDS engine. You'd have to do an insane amount of patches to allow that.

Also the NDS is probably not powerfull enough to do the rendering job for 3 seperate layers.

The most impossible thing is the Layer infront Mario. 2D bg tiles can never be rendered infront 3D sprites.
You'd have to create your own render system for these which would rely on OAM objects, which would cause an insane slowdown if they are used to much. Also the OAM tiles/pallettes are limited as well.


All in all: Never


Edit: And remember: Replacing stuff is "easy". Adding not.

I kinda doubt the "NDS not powerful enough to do 3 layers" thing. I mean, it can use the 3D hardware, can it not? But maybe about the NSMB engine thing.

I'd like to ask how will the recent advancements in ASM hacking affect the release of the hack. It's no mystery that You strive for utmost quality and always improve even levels that are done. Will those new hacks (unlimited music/tilesets) affect the release date of the hack a lot? I was hoping to play it for this years christmas, but I understand that You might want to re-do and include a lot more content now, which is of course great and I want to play the best game possible.
Thanks in advance for answer
Kind Regards

I'm hoping to still make a 2016 release.

That said, there are questions I will need to ask myself. For example, let's tentatively say custom world maps would be possible. Should I include those? They'd push the release back a lot.

Why not release a demo?
However, it is not a normal demo, but a demo of eight unique levels, eventually you could export eight levels from your hack and place in a clean rom, so everyone could at least try to level

Yeah!
Let's waste time putting together a demo

Great idea.

The world maps aren't a crucial part of the gameplay and those that I saw in Your YT videos looked very good. That being said I know that those are 'just' retextures, and fully custom maps (I assume 3D models, unless a 2D map engine would be created similar to Newer Wii) would increase the quality of the hack. I guess it depends on Your motivation to spend a lot of time on something like that, I certainly wouldn't want You to lose motivation towards the end like in the case of Another Super Mario 3D, especially since it's a lot of work for what is pretty much a visual change.

That's what I'm thinking myself, but like, every second question I get is "Will there be custom maps"

I could make the demo for you.

Anyways, whenever it comes out, you should be comfortable with the results. You won't want a hack without something you wanted it to have. Also, releasing it on a holiday might be a smart move.
