I still like this game, but it's getting a bit too hard to keep up with. I'm playing on original hardware (no save states) and it's really rough. It seems like if I had more items, I might be able to go through a bit easier. Do you happen to have a hi-res version of this file, so it's easier to see where the items are? I'm about to give up: http://i173.photobucket.com/albums/w64/legendoflinkmapslegendoflinkmaps/all_worlds_levels.png

Bad news, my save game ended up getting corrupt. Does anyone have a .sav file they'd be willing to email me? I'm at this point in the game:

Tonight I'll be releasing yet another revision, but it's a very important one. I'll explain and submit the patch when I'm home.

Main first page has explanation & new patch.

Deals with controller 2.

There are 2 hidden features (aside from the Up+Start) that are used by the 2nd controller.

If you are asm savy, look for the ram register that controller 2 uses to output the pushbits bring activated. Then search the "rom" for (LDA$ ##)

That's as far as I'll go lol! I'm really surprised nothing has surfaced publicly after all these years.

Good hunting.

Sadly the only thing im good at with rom hacks is playing them. Given all the other major changes, I'm guessing controller 2 can be used to play enemies and/or a hidden coop mode, but button mashing gets me nowhere!

found it in less than 5 minutes. well... 1 of the 2 apparently.

guitarpalooz:
try doing it at the file select screen

I dont consider this one.. a secret honestly. but it's understandable there's no screen space for it though.

I see what the other one is, this one is defintely a real secret, but "only" if i can get the FCEUX code-data logger to actually begin logging the code from it. i dont know where in the game i have to be for it to start.

edit: found it, if im allowed to say just a hint.

try it out when you open a treasure box (im not sure if it works on every treasure box) ...but just uhh, try one of them anywhere i guess.

The main secret that kuja killer found, can be done at anytime/anywhere, during in-game play only.

thanks. although the romhacking.net site still has the 7-18-2016 version of the game instead of the updated 1-10-2017 version. can you also post the new version on the Romhacking site?

I don't know how to do that over there, it's always been confusing to me. I've basically been relying on others to inform/upload my patches to that site.

I even tried recently updating the description of my game, to show that it requires 32kb of sram, not 8kb, but it never changed over.

So it's out of my hands unfortunately, I love that site, but for uploading it has always been a hassle for me.

Dont know what donor game uses 32kb of sram?

Most usual MMC5 games uses 2x8kb, like L'Empereur..

Is it possible to make a version that only has 1 save slot and has lesser requirements for that big sram?

Or can the SRAM-chip be replaced in those, anyone done this?

Last patch (2016) I got the saves to "work", they glitched out sometimes.
2017 patch it doesnt save at all, noticed the 32k save requirements after testing..

https://wiki.nesdev.com/w/index.php/ExROM

I have no plans to go back to this game. I've always wanted 3 save slots in my game.

For those that wish to edit my work themselves, to include only 1 save file, it will take someone with 6502 knowledge.

Using the FCEUX debugger, goto the registration screen, run the code data logger, open the her editor and search for string values "2901" or "2902" I forget what my pushbit registers are. When you search for those and they are gold/yellow colored, then that's where you want to be. Those are the checks for if left or right have been pressed.

You will have to either bypass this routine with a simple JMP, or NOP out my pushbit checks. I honestly can't remember if I reuse that function, but I believe I dont. Anyway, you need to bypass that routine, so that you are unable to cycle through the files.

Thanks for the reply.

This is something I've never done so I hope someone else are able to do it.

Honestly, Im so impressed with the hack (and the all stars hack) and are really eager to play it on actual hardware.

Thanks for all the great work put into it.

SMB allstars can I live without save working, but this zelda hack is to huge.


EDIT: BTW, could you post previous versions of the hack? That did not require 32k sram?

Hello, I have a Just Breed cartridge that is in not so great cosmetic condition. This contains MMC5 hardware and I don't feel so bad to mod it in its condition. Also, Just Breed is quite unusual because it is held together with screws instead of plastic clips!

I am looking at putting in Legend of Link, along with the English translation of Just Breed, and also Metal Slader Glory (and maybe someday if Metal Slader Glory gets translated I can reflash it; I'm planning to reserve 1024k PRG and CHR just in case the patch is bigger.)

I am looking at putting in a bigger SRAM chip and assigning a section of it to each game so that they can all save. I have some 32kbyte hm62256blp chips that would be perfect, but I'm not exactly sure how much SRAM The Legend of Link needs.

In the 7-18-2016 Read-Me file that comes with the patch, it says it needs 8kbytes SRAM, but on romhacking.net, it says it needs 32kbytes:

http://www.romhacking.net/hacks/2136/

How much SRAM does this game actually use? Is there any particular portion of SRAM that needs to be nonvolatile while maybe a different section can be lost each time? (Not sure if that helps me anyway, but it would be interesting to know.)

Edit
Sorry I didn't read much in this thread before posting. It is a fairly huge thread and I didn't even try. I see now that 32k is required and that the instructions just hadn't been updated.

Could you post a memory map of the SRAM chip? It would be awesome to see what sections are nonvolatile, which parts are volatile W-RAM-only, and which parts (if any) are unused.

Do you have your game on a cartridge yet infidelity? I think we owe you an actual cart for this awesome game.

Yeah I need to clean up the main page here, like I did for All-Stars.

Legend of Link requires 32kb sram. All the sram is used from $6000-$7FFF.

That's okay, I just need a bigger RAM chip, or just 2 RAM chips if I want to do an MMC5 multicart. No problem.

I would seriously build a famicom cart for you with 4x AT49F040 in PLCC-32 sockets sticking out the back of the cart. (2 for PRG (total 1024kbytes), 2 for CHR (total 1024kbytes)) Of course I would program it with the latest version but it would be nice if you can update/modify it yourself later.

- Do you have an EEPROM programmer that you can reflash AT49F040 with? I use a cheap Willem.
- Do you have a Famicom? If not, do you have a Famicom to NES adapter + Game Genie? Just Breed is too long to work on its own with a Famicom to NES adapter in a front loader, it would need to hang out via Game Genie.
- Other people could pitch in an adapter and game genie for you if/when I provide a Legend of Link cart if you want it.
- The cartridge will automatically support expansion audio should you want to experiment or swap in a different game on the ROM chips. If you have an NES, it would need the capacitor + resistor added to use the expansion audio.

I think we need to be pretty serious about giving back to someone who does what you have done for the Famicom / NES here. You made our Nintendos do something totally new and that is awesome. I have done a number of cartridge mods, see some of my very first ones here:

http://www.d.umn.edu/~bold0070/projects/nes_carts/

Also:
http://www.d.umn.edu/~bold0070/projects/sunsoft_5b_fme7_audio/

I am good at it, and I will do it, I have all the parts and pieces. Just let me know if you are willing to accept it and allow me mail it to you.

Edit:
Not sure if/how PMs work here, but I have an account by the same name at romhacking.net. You can send me a PM there if you want. I would start another thread for progress updates on your cart so you and others could follow along and learn how to make their own.

Edit:
Looks like romhacking.net is having major problems and won't be back soon...
