I always wanted to do a Super Mario Bros. 1 hack where I use the patch: Break Brick β
Fireballs can destory brick blocks.

This upcoming hack will be sort of the spiritual sequel to my hack Mario's Keep.

Mario will break blocks using bob-ombs.

Also I'm working on some animations. Here's some waterfalls:


I think it will be a pretty straightforward hack with some puzzle elelments but it's also possible to speedrun the levels.

Looks like fun! I'm not a huge fan of the SMB1 engine, but you make the game look pretty and fun enough to move me t give it a shot.

What logic do you use for animations? Bank swapping? If so, you must have done a mapper change, MMC3 maybe?

Mapper 3 - VROM (CHR) Switch / CNROM.

Yes. It's a animation patch:

Once patched, they will be three extra sprites sheets (4 in total), so that you can edit the sprites. You can't open the hack in SMB Utility after patching this.

So what I did was to repurpose vertical ropes of balance lifts into waterfalls.That's fine and all, but the waterfalls would be brown because they (ropes) share palette with the ground. I had the hardest time separating the palettes!



This is a perfect example of how cryptic this game can be to hack. I have got access to A Comprehensive Super Mario Bros Disassembly and still I could not find a simple way of just assigning a new palette to ropes.

So what I had to do was to take out the top of the cloud metatile (because thats's a different palette). ROM adress: 139A. And put it in the ropes metatile adress: ROM 0BBC. And that affected the bushes so I had to switch metatiles for bushes as well. That alone took me a week, but at least I'm learning stuff.

It looks interesting at the initial stage. Waiting for the full version

If I recall correctly, the palette attributed to a tile is determined by bits 6-7 of its Tile Code. Therefore, Tile Codes 00-3F have palette 0, 40-7F palette 1, 80-BF palette 2, and C0-FF palette 3 (cycling colors). The pointer table for tile mapping tables is at B08. Addresses are B10, BAC, C64 and C8C, for tile mappings of Tile Codes with palettes 0, 1, 2 and 3 respectively.

Thanks. I´m not sure I understand how to put this information into action, but I´m fine with my solution for the time being. Everything works fine.

There are some stuff I wish to add to my hack though. Which I don´t know how to do.

- Decrease time on the intermediate screen

- Make Toad/Princess text say different things at the end of world 6, 7, and 8.

- Make end music play at the end of both world 7 and 8.

- Custom music

Pretty mean lookin' animated Bowser.

I'm now pretty much finished with the graphics and levels. Now I will try to hack the music. 

[diablo666]

This Dragon looks really more formidable :-)

[NesDraug]

Goombas are now Bob-Ombs.

[diablo666]

Good Idea

[Arcade-Elite]

Looks like this Bob-Omb theme would be perfect for a Wario game  keep up the good work.

[NesDraug]

Bob-Omb Battlefield. Work in progress. Super Mario Bros music engine is pretty cryptic and hard to hack.

This is gonna be gangsta when it's done. 

[diablo666]

How I understand you. but I'm sure you can handle it :-)

Goombas are now Bob-Ombs.

As you can see in the gif, Mario will always superjump in this hack. I think I saw a patch or hack somewhere that lets you do a superjump only if you HOLD A.

Any ideas on how to achieve this?

[Cyneprepou4uk]

Add a condition to a superjump initial physics.

Add a condition to a superjump initial physics.

Good idea. I have no idea how to do though.

[Cyneprepou4uk]

Well, first of all find an address that holds gravity value or something, and take notes on what's the difference between these two jumps. There can be several addresses involved. Keep working on that until you'll be able to manually convert one jump to another by modifying necessary RAM values at the start of the jump.

Then there will be some coding involved, of course, where you need to hijack the physics setup for the jump and write different values depending on whatever conditions you need.

[NesDraug]

Well I made it. Thanks to StudsX (who is working on a music tutorial) I managed to change all tunes in the rom.
