Super Mario Bros Co-Op hacks by NesDraug
« on: March 28, 2022, 05:18:00 pm »
I'm trying to port other smb hacks to the Two Player Hack (by CorpseGrinder and Ti)
I do not take requests but I can share information on hacking the Two Player Hack.

I've already made a Co-Op version of my own hack Mario's Keep.

https://www.romhacking.net/hacks/5903/


I'm almost finished with reworking a old hack by Googie to make it co-op.
Luigi's Chronicles Feat. Waluigi


I tried to give Waluigi a separate sprite. I have managed to do so in the original game, but I can't move my changes to the Two Player Hack, unfortunately.
 

I've got two more co-op smb hacks in the works. I'll post here about them later.

That's an interesting twist on the game. Having levels where you actually need two players to complete would make for interesting puzzles, although I imagine it requires quite a lot of nifty ASM coding.

Well the hard work is already done. The game is already two player co-op and there's this program that let's you import levels to the two player hack.

Importing new functions is harder but it can be done by comparing hex data in the two player hack and the original rom.

I did som asm just to give the players a star if they collect 100 coins... but something went wrong when i tried to place the new hex in the Two Player Hack... instead of invincibilyty at 100 coins you got death at 1 coin... but ONLY Mario!

Code: [Select]
adress:
BBEF - 64 = 100 coins
BBF7 - change FE5A07A940 into 8AA820EBD9 = Mario hurt by coins

This was a great find. Now I just need to design the levels. Luigi can remove coins that would kill Mario. And Mario can bounce on coins if he hits them from above!

I managed to give Luigi a separate sprite in asm.


Unfortunately I can't port my changes to the Two Player Hack. Source code for the Two Player Hack is not available.
Any ideas?

Link to the asm file with Luigi separate sprite

Well, I consider Luigi's Chronicles Co-Op feat Waluigi finished!



It will be released soon on RHDN!

Strange I never saw it on the newest hacks page. Ah, well here it is:
