Batman Bros. - SMB1 Two Players Hack
« on: November 30, 2018, 07:40:43 am »
So I wanted to do something with that awesome Super Mario Two Players Hack by Corpse Grinder and Ti.

This is Batman Bros. Co-Op.
Batman and his long lost twin Batbro find themselves in a very dark Mushroom Kingdom.



Link to IPS-file: (version 0,6)
https://www.dropbox.com/s/j7o6g9j5f22sy1x/Batman%20Bros%20by%20NesDraug%20v0%2C6.ips.zip?dl=0

ROM: Super Mario Bros. (W) [!] [NES] - GoodNES V3.23b




It's a real chore hacking this rom because I can't use any of the custom smb1 utilities since the information in the two player hack is altered.

- Sprite editing in NES CHR Editor
- HEX-editing in FCEUX to fix the colors

This is a work in progress, please tell me what you think or feel free to ask me if you have any questions.

Could have perhaps dragged the SMB1 new level data in the two player hack (via graphics editor) to see if it works fine.
Is the pool clean?

Hes simply menacing adorable. Like LEGO Batman.

Please do, and report back if you encounter any bugs. I haven't managed to change all the sprites for all enemies yet. I was thinking of tweaking the physics a bit giving batman more speed and jumping power.

UPDATE
- Fire flower is now Bat Shurikens
- Player Two is now grey instead of green in underwater levels
- Mushrooms are batmask with blue eyes

I tried to replace the tile card and write BATMAN instead of SUPER MARIO BROS. but I simply couldn't get it to work. I think I'll call it a day. I'm quite satisfied with my hack though it could be improved.

UPDATE: (I think this is the final one)



- Stars are now bats
- Fixed game over bat symbol
- Well, that title screen is the best I can do

The title screen is a little bland. Are you planning on sprucing it up? If not, I could attempt it

Actually, no. I created a pretty sweet-lookin title screen, but couldn't put it in because all of the data is offset or something. Shame, really.  :-\

I agree. This was the best I could do. :P
I tried to make a cool title screen but I don't know how to insert it into the rom without damaging the code for the two player hack. Remember I'm working with an already patched version of SMB. https://www.romhacking.net/hacks/4180/

If someone know how to do it. Please, feel free. :)


Edit: Just out of curiosity. What did your title screen look like?

It seems really odd, it's all in the right place but if you open the patched rom in a graphics editor, there's about two tables of empty space at the beginning. I mean, I'm no expert but that seems weird to me.

The two player hack is a pretty unusual hack so I guess Corpse Grinder and Ti had to move the data around to make simultaneous gameplay possible. I have no idea why, but it sure limits my possibilities.

After all, it's quite not intended that this "base" hack is user-friendly to make another hack out of it.

So I finally managed to make a descent title screen for Batman Bros. Co-Op!

- I used the original rom Super Mario Bros. (W)[!] and drew the graphics in Tile Molestor.
- Then I placed out the new title screen with SMB Title Screen Editor
- The title screen data is in the end of both the original rom file and the Two Players hack. Copied the new data in FCUEX.

Title screen location in the original rom (it goes all the way to the end of the code in the romfile)



Title screen location in the Two Player hack  (it goes all the way to the end of the code in the romfile)

Okay! It's finished. Version 1.2 is getting a release any day now.



I've fixed a lot of bugs and edited enemies, backgrounds and even managed to edit the levels (slightly)

Yeah! Now it's released. With slightly altered levels. Yay!

I'm thinking of doing new levels and make a completely new hack based on this... But inserting new levels into the Two Player Hack is quite a chore.
We'll see. ^^
