Added a new ability to this hack, princess now picks things up at the same speed as toad.
Uhh, she's supposed to be slow with picking up stuff. Her only grace, so to speak, is her ability to float.


I like combining powers I did the same thing in my castlevania 3 hack I gave alucard a sypha only special attack. Worry not it's really easy for me to restore the princess pickup speed that's just something I added for preference. I find it fun with princess having that extra ability. I'm not making these hacks to please people I'm making them for myself so I make them the way I like.

As for the play testing I did actually find some bugs, all of which are now fixed. I cleared the game start to finish and it works great.

Is it practical to do a full code/data log of the ROM before you go and hack it? I did this with Megaman 1, but not at the beginning. I did it at some point early on though, because I was worried about accidently overwriting original game data. And with a conversion as big as the one I was doing, I didn't want to take any chances of a screw up. And ultimately I'm glad I did do the full log of the original game, because I did wind up putting code close to the original game code, simply because it was in a bank that was already loaded.

So I was just wondering what you guys do before hacking the game you want to hack? Do you play the original game completely through to log everything, that way you know where all the free space is? Or should I just not worry about it so much. Is it highly likely that a small block of 00s and/or FFs denotes free space?


I always aim to expand the rom whenever possible. If the original game is 256k and the mapper supports 512k, make it a 512k rom and just write your own bankswitches in the free spaces at the ends of the original banks. I have yet to expand a nes rom so I don't know how many (or few) games make full use of what their mappers are capable of. Luckily with the gameboy it's fairly easy expanding roms since the mappers are almost all 100% compatible.

I always approach a project from the perspective of getting the most out of the possible hardware before doing the coding. It's always good to read about a mapper / cpu / whatever you're using and learn how to set software controlled hardware options to get more abilities out of whatever chip(s) you're working with.

Amen! Always stick to that mentality with this stuff here. :-)


That's why I'm posting here. I tried posting my work on other forums and people trolled me to death for not making it how they want and also for not releasing it for free.

I've never actually sat down and played this hack beyond a couple of stages. I cleared the metroid + saving hack by snarfblam....man what amazing work.....that hack runs flawlessly. If I ever found something not right with the mario sram hack (or any hack for that matter) I'd nicely mention the flaw to the author being careful to thank him for the amazing free work and mention that if he's too busy to fix it that's no problem. If the author is too busy I would just research and fix it myself or make my own hack that does the same thing from scratch.

This work is amazing regardless. Even if it's not perfect it gave me some great ideas and made me realize some great ways to improve what I thought were games that couldn't possibly be improved upon. I love infidelity's work everything he does is an improvement and very original (snarfblam too, also tomaitheous). These guys are what inspired me and gave me some great rom hack ideas. A great idea and working proof of concept hack are better than 1000 common hacks.

Rom hacking takes a lot of time and effort, sometimes you can go back and improve on your old hack and fix things. When I started rom hacking I actually started by fixing broken elements in other people's mostly completed work that had bugs since around...2006. Really people should be thankful this stuff got done at all, and even more thankful infidelity was nice enough to release it for free.

Seems a bit strange to me for nes games. I found every nes rom I've worked with the end of each bank always has a block of ff data and that's always unused space. I just convert these blocks into ea (nop) data and then jump to them to insert new code. I guess this is for stuff that needs a serious amount of extra space.

Can you provide a link or something? I thought I'd have to make one myself, preferably looking like the FDS version.


http://www.romhacking.net/hacks/1186/

Seriously man, I went to google and typed in "metroid + saving", not exactly hard to find if you try.

I like the changes except for mario's skin colour. No need for the sauna look, really just a preference thing. Hopefully we can see a video of it in action someday, pictures don't do enough justice.

Hold on...the rom palette hasn't been edited? Palette changes are done by using an emulator palette replacement file? That's no good for playing on the real thing unfortunately. That's technically not romhacking, just emulator options changing.

I recently got into the goddess of wisdom hack, my god...it's amazing. I think lttp has the most hacking potential due to the huge puzzle nature of the game. The potential amount of fun new puzzle filled worlds is endless.

Perhaps an editor like ntrq that can be used to compose music? Just need something to help speed the process up.
How does it work? Is it like FamiTracker? What's different?


Uhm...google it? It lets you compose nsf files on an actual nes. You're basically forced to program music in the format real nes music would be coded (write blocks of notes in certain lengths and then arrange the blocks in a pattern to form a song). Here's a nsf I composed in ntrq:



NTRQ certainly isn't beginner stuff but it's much less time consuming than manually writing something in hex.

I guess I really wouldn't know I've never done changes that need enough space to have to look into expanding the rom or freeing up serious amounts of unused space.

New stage song really adds amazing depth to your hack, totally makes it a new awesome experience. Hoping you'll change the boss fight music too. That equip music uhm....well....looking forward to a better version

Wow, that's dedication. I wouldn't have the patience for that much work.

How come you don't want people hacking your hack?

You won't find me playing this hah. I'm too old (pre-pokemon generation). I really think people who weren't little kids when pokemon came out don't get it, myself included, I never understood the appeal. Same thing with power rangers, I don't get the appeal.

And yes I cry seeing most of the romhacking talent being in the pokemon community and staying away from the games I love. Luckily I'm slowly learning this stuff so I can at least give hacking love to these less popular non-pokemon games.

Yeah, I'll probably choose something else later. To be honest, that was my test song and the first song I ever inserted. Not really sure what to use there though.

Thanks for the compliments on the stage theme, I'll try my best to get a good boss theme in when I get the chance.




I don't think the stage theme could be any better. I'm pretty good with you inserting whatever music as long as the song is decent.

Well, still thank you for your kind remarks Drakon.

I was born in 1991. Pokemon actually got started 1 year before that and was released in 1995. Mew was surprisingly copyrighted before the series as a whole.


Yeah in 1995 I was 15. My 1995 involved chrono trigger, final fantasy 4, super metroid, link to the past, mario world, other snes classics. I wasn't playing nes in '95 because top loaders weren't so easy to find (got tired of failing zif systems) so I focused on the snes. Also I didn't have a gameboy. I think the first gameboy I ever owned was my used sp that I bought in 2007ish.

I thought pokemon hacking is popular because of all the kiddies of that generation growing up with it. Where did all this info come from? Fans of the game?

And yes...it saves your high score, I was careful to include that in the video.

Cool, so it basically restores everything that was cut. Like that hack of sonic 2 where they re-inserted all the removed worlds.

Seriously, someone needs to make a gb / gbc emulator that's as powerful as fceux debug build. GB / gbc needs more trace logging to save me the effort of backtracking code.

There is this one glitch, if you haven't caught it already, that causes flickering in the status bar. All you have to do is change these values:

3F7B2: 0D->16
3F8E0: 68->EA
3F8E1: 8D->EA
3F8E2: 10->EA
3F8E3: 40->EA




You could jump it to unused bank space from wherever that asm is, read the current level and either execute or not execute that code depending on what part of the game you're in (since the fixed code is a bunch of nops). I've used that trick in a number of romhacks to fix issues. This way the fix will only be executed when not facing bowser. I'm sure there's some area of ram that will specify when you're facing him or not. You could always write your own data to unused sram space too.

It's a massive pain to do, but it puts your hack on a whole new level above everyone else.
