Thanks for the explanation and the words, bogaa :)
It really helps understand the differences a lot more between them.

Zelda II two players, would this be a good option for the project?

http://www.romhacking.net/hacks/5243/

It seems like a heavy ASM hack for Zelda II.
And tbh it kinda breaks the pace of what I'm attempting to do with Z2 Redux (or even Z1 Redux).
Zelda has always been a single player game, and while the PoC the guy did is awesome, I don't see myself implementing it in the project, much less since it will most likely cause conflicts with code already done for the game.

Besides, for Zelda 2, I think we are at a good enough position, with only the File Select hack remaining.
Adding more stuff would just push it back even more, like ifightdragons mentions. I don't want to keep the project in hiatus for more years than it has already.


As for Zelda 1...
I still haven't done much progress :/
I'm struggling with the mapper stuff... still. lol

Just played through the newest version and it's pretty damned flawless.
Only real thoughts I had (which you probably already thought of) are:

I wonder if there might be a way to add a couple rooms in dungeons or replace rooms with relatively worthless hints and add a couple places where you could buy increases to your arrow capacity, like the bomb upgrades. Like you start with 30 and maybe one spot to increase your capacity to 50 and a second to increase it to 70, and then when you get the silver arrows it bumps you up to 99.

Another little idea I had today, that might be impossible to implement, but just throwing it out there: I wonder if there'd be a way to add a second upgrade to the shield that makes the big shield not just block, but reflect the projectiles back at the enemies, like in some of the later games?

And then just a personal annoyance with the original game: I wish there was a way to turn off the magic book's effect on the Magic Rod, so it doesn't always produce fire when the beam hits. Too often, I end out smacking into residual fire that it leaves behind. I know I could always just not get the book in Level 8, but I just wish it was an effect you could turn on and off.  Again, that's not a flaw you introduced to the game, it's just an annoyance that's always been there.

Anyway, amazing, near-perfect work so far. Can't wait to see what other surprises you have in store once you have the mapper hack worked out.

Can I ask what the offsets are for enemy health and strength? :D

I did talk about this once here:
It is more about how to "find" make documents of enemy health/damage table..

Here might be other offsets of interest: https://datacrystal.romhacking.net/wiki/The_Legend_of_Zelda:ROM_map

This table will probably be hard to find in the disassembly till they are documented well then you might get lucky with a good search.

I had in mind to make a walk-through of what goes into mapper conversion. How to add some CHR banks and make code for some animation. This would be some text and work to cover properly. It just crossed my mind that you will only use this for the waterfall? I think you could be a bit more ambitious when you go all the way to add a mapper there could be some of the features in full use.. Else it is not really worth.. (It would be great to add it anyway as this might be used as learning material to do hacks. May be someone will find better use for it)

Here what crossed my mind. You have CHRram and you can just write a routine to update some PPU addresses. CHRram does allow for some incredible effects. Just look at Battletoads to find some of the possibility.

I tested with Legend of Zelda and 30 byte is too much but 20 byte+ every frame seem to be no problem. I made some prove of concept code for you to improve on. Since I think you like a challenge and get better at coding for the NES. Not sure if this is easier then addin CHR but for sure a different challenge.

Here my prove of concept code at work in a video.
https://youtu.be/jFygmah8_po

Here the code to work with. You can give me feedback as usual what you think and how it goes.
https://www.dropbox.com/s/tch7u0tuwm3qm3o/ZeldaWaterFallExample.zip?dl=0


Notes:
- There are some additional notes at the beginning of the code where graphic pointers are if you like to work on the MMC5 Stuff.
- Task for the WaterFall routine in the normal game is to add 2 more tiles. Then write code to control the animation. (You would need to spread it in a smart way to not conflict with the limit..)

Insteresting work you did there, bogaa.
So let me see if I got this right...
You are still using the original Zelda 1 mapper to make the waterfalls have animations without relying on additional mappers?

As for touching on this point:

I was aiming towards making animations for waterfalls and overall water animation, so the water tiles can be seen moving instead of being static.
This could also apply to other aspects of the game, perhaps even to other places like lava in dungeons or , and having the option to animate pretty much any tile would be a good option.

However, if your code does allow for waterfall/water animation, then going the full-on Mapper conversion would be overkill, if this option is suitable for that end.

I'll check out the code later today hopefully.

Yes the animation work with mapper 1.

- When using RAM CHR you can have different animation. You just need to be smart about how to implement them properly since moving data uses important CPU cycles during the NMI. When you try to do to much in one frame you will get glitched graphics. But it is no problem to have some animations going on while playing. The most resource heavy thing I did find on the PPU side is pressing pause since the Vertical scrolling + tile-mapping stuff happen.

- Doing a new mapper sounds more overkill to me when you just like to see some bubbles in the lava or some waves in the water. When you would use bank-switching for this task it takes way less resources as it is a simple ROM bank switch.

May be the redux hack might come to a "end" soon. I think after a release with the impotent improvements you can still add additional optional patches to the git. May be some people might like to share patch resources like this so when you do hacks everything is on the same page.

Some idea for optional patches.

- Diagonal movement
- New Boss attack/patterns. Or full Boss revamp.
- Enemies with new skills.
- MMC5 with CHR setup for animation
- New Sword mechanics. Hold to charge.

For some people this is too much and will not fit the redux but might fit the optional section well.
I did not look at how you arranged new added code. I guess this could also be a long time project how to arrange/improve everything. Make sure all the patches work independent and have something like a overview document to look up hijack points used and give a overview on the project so if you like to add things in the future it will not end in disaster.
And things like this will not affect end user that just likes a revamped Zelda. And still will keep this thread alive to do things with this game. If this fits your interested as well.

Several things:

1. Projectile speed. It appears there are several. Wizzrobe waves are fast, lynel's beam is faster than Link's, etc.

2. What the magical rod can or can't hurt, physical and otherwise. By default, wizzrobes are unaffected.

3. "Leave your money or life" guy. It'd be fun to change the container and rupees to something else.

I couldn't find where to change them.

Has there been any recommendation about giving a hint on the trees that can be burned on the World Map? Perhaps a very subtle discoloring?
