The mic is accessed via the controller port. The only requirement on the cart is that code for the mic be present.

Have you verified that you're using the correct version of the ROM? Not only should you be using the PRG-0 version, but you also want to make sure the ROM you're using has the correct checksums. From the hack's page:
    Legend of Zelda, The (U) (PRG0) [!].nes
    CRC32: D7AE93DF
    MD5: 337BD6F1 A1163DF3 1BF26336 65589AB0
    SHA1: DAB79C84 934F9AA5 DB4E7DAD 390E5D0C 12443FA2

Some emulators can provide the checksums for a ROM, or you can use various tools such as ROM Hasher. You can see that my copy of Zelda has the correct SHA-1.

Why not download a whole bunch of patches, apply them with your patcher and with another patcher in a batch operation and compare the results for discrepancies? Of course that doesn't exclude additional tests for specific modes of failure, but would go a long way in demonstrating that the tool works well in practice.

You can also place it in the 32-bit system folder (C:\Windows\SysWOW64 for 64-bit) and register it using regsvr32 from the command-line. More info here.

I remember this one in particular. Those graphics are nothing short of magical.

Personally, I'm not terribly interested in preventing carting. I'm not very fond of repro makers, but they aren't worth losing sleep over. One idea I've seen tossed around recently is adding a message to the game to the effect of "If you payed for this, you've been screwed," but that's so easy to remove, it almost seems pointless. Maybe it will deter carters with a hint of decency. Who knows? What's more important to me is that if somebody wants to play this on a flash cart or even wants to cart it for personal use, it would be a shame to screw that up.

RHDN doesn't host incomplete or beta hacks. You can link to the patch on the forums and keep people up to date there. Once it's ready for a proper release, you can go ahead and submit it to the RHDN database.

i wonder how old, HaxorKyo, is. because his/her hacks all strike me as REAL immature and childish. i'm guessing the main purpose of these hacks are nothing more than trolling.

I interpret it as a statement about how easily people are offended.

I want to say yes, but it's been a while and I'm honestly not 100% sure whether or not I used any continues on my best run. My real goal is to have fun. ¯\_(ツ)_/¯

But congrats on your bullet dodging success  ;)

Try updating 7-Zip. Some of the newer versions of archive software permit or even default to settings that result in better compression but that aren't compatible with older versions. I've run into it with both .rar and .7z.

You needn't be impressed. For people who didn't play it a lot as a kid, it's a much more difficult game. My brother saw me playing Trax's hack and was amazed I could dance through the bullets and move more than an inch without getting killed. Seems to me most people find it to be a very difficult game or a rather easy game, with little middle ground.

ROM Hacking Discussion / Re: How do you make an SRAM hack?
« on: September 26, 2015, 12:42:22 pm »
And in case anyone thinks that sounds too complicated, it'd probably be as simple as splitting and stacking the ROMs and then applying an XDelta patch.

I believe the current guidelines are somewhat broken as far as NES hacks are concerned. While it is clear that a checksum is required, it is not clear if it is over the header or not.

It is not required to be either, but I'd strongly recommend you state which one you're providing if you make a submission. Emulators will give you a hash on the unheadered ROM. General purpose hashing utilities will give you a hash that includes the header (and byte-swapping/interleaving/overdump/etc). Or, for completeness, you can provide both. ROM Hasher spits out something like this, and couldn't possibly be easier to use. Everyone is also certainly more than welcome to use a format that does file verification.
No-Intro Name: Sonic 3D Blast ~ Sonic 3D Flickies' Island (USA, Europe)
(No-Intro version  20130710-102701)
File SHA-1: 576F578D0ED9740A0325F6EB4C7530D86123DD29
ROM SHA-1: 89957568386A5023D198AC2251DED9DFB2AB65E7

In the case of NES, if you see that the file hash is wrong but the ROM hash is right, you can be pretty certain it's just a case of header garbage.

I asked around #metconst, and this is the recommended solution to your particular issue:,560.msg28035.html#msg28035

SMILE RF was also highly recommended over the standard version.

As for the Windows version, I won't do it myself, but I am working on a comprehensive document where I explain the main parts of the game, where to get the data and maybe some explanation on how I did it, so that someone else can use it as a reference.

I'll be happy to make an editor for anything that's documented.

I don't know.  I think writing a disassembler is a good way to learn those kind of things.

That's a good point. Maybe there's a better way to word what I'm trying to get at. You have to be willing to learn all those things. If you've successfully written a disassembler, then you've advanced to the point where you have a very solid foundation for understanding assembly. You've got to do the work to get there.

I feel the need to point out that if you don't understand the following (among other things)...
  • How to write meaningful 6502 ASM
  • How an assembler converts this to machine code
  • How to manually convert machine code back into ASM will never be able to write any kind of software that reverse engineers code. It's like trying to drive without knowing how to shift. You'll never get anywhere.

Scratchpad is strictly for the purpose of submitting files to the database. I approved the submission so the file can be downloaded from the hack page.
