Sorry about that post.  It just bothers me when people who have no idea what's involved with rom hacking have very strong opinions about it.  You made it sound like such a simple thing to do.

I'm wondering how this have never crossed anyone's mind after all these years lol. I think a patch would make this possible. I played with PAR codes for the longest and just can't get anywhere with that. Its something that's clearly in the game so I'm not sure why this task has been so hard.

Because you have no idea how to romhack and therefore no idea how difficult it is to do that and therefore have no idea why this task would be so hard.  If you really think "old games use software that isn't that complicated" then how about you go ahead and figure out how to do it?

I'd like to see someone who makes claims and delivers on them.  There's far too many people saying they're going to do a hack.  People list this insanely huge and complicated idea of a hack which usually gets as far as the title screen and whatever easy to use editors allow them to change with a few mouse clickedy clicks.

I don't care what direction you take the hack as long as you keep us up to date with pictures and videos on a regular basis.

That being said story...story....uhm

Sure a temporal rift caused them all to find each other and they're working to fix it, sorta like chrono trigger but instead of time it's across dimensions or something.

And yes, I look forward to it.

I decided to take a stab at hacking megaman 2.  The result is a version with sram saving that works all the way up to the last stage of the game and even saves your ammo.  In this hack I altered the following weapons:

The freeze weapon (I forget the name) now can be turned off by pressing b button when it's on
The crash weapon can now be detonated prematurely by pressing b button after it's been launched
The leaf shield now has been heavily modified, it now uses 2 ammo points when you fire leaf shield but you can now walk around with it.  When the leaf shield kills something it uses up one ammo point.  When you run out of leaf shield ammo the leaf shield shoots off.  You can shoot the leaf shield at any time by pressing b button again.

The goal of this hack wasn't to alter the original experience into a new game, rather to simply fix the things I always felt the original should have had.

Keep at it craftvania, and be patient, picking apart a compiled assembly rom can take a lot of time.

Man I really wish you'd sit down and learn how to do this stuff.  I've love to see what your version of megaman 2 is like.  Anyway about the ability to stop the freeze attack, I sat down and got it working:

It's a thing of beauty.  I've wanted to be able to do this since I first played megaman 2 as a kid.

I could do the crash bomber thing but I have zero interest in that.  Perhaps you can use that as motivation to learn how to rom hack yourself.  That would be a fairly good beginnerish hack.

Needs more of this:

I made one myself that works all the way up to the final stage and it saves how much ammo your weapons have.

I completely disagree with satoshi matrix.  Having exactly enough crash bombers is what makes that boss fun.  I like having a boss where I have to plan my ammo and strategy.  I think that crash bomber boss is part of what makes megaman 2 great and more games today should have more elements like this.

I do agree with that flash attack idea, that's brilliant, I'll give that shot.

You first need to learn assembly for the nes.  Then you need to learn how to use all the tools in fceux.  I learned fceux tools (debugger trace logger etc) by reading the fceux online guide and reading threads of how other people used them.  NES assembly I learned by typing "nes asm" in google.  There's your tutorial, type what you want to learn in google.  Once you learn these things you can make the game breakpoint around the area you want to hack.  Once you learn the assembly well enough you can read the disassembled code and understand what it's doing.  Once you understand it well enough to know what's going on, you can change it.

It's impossible to make a tutorial for actual game programming because every game has unique programming.  You have to learn how nes assembly works and learn to read and understand the disassembled code.  If every nes game ran the same way there certainly would have been a universal tutorial by now.

It's a lot of work and I found a lot of the online information to not be beginner friendly.  I suggest you break this into small steps and take your time figuring it all out.

Killer idea for a hack.  I took it a little further and made it so the menus default to "difficult" and "continue".  I also removed the subtitle from the title screen and made the post stage menu default to "stage select" instead of sending you back to the title screen.

I've been playing through this.  This hack is quality.  There's no bugs or issues whatsoever from what I've seen.

I removed the subtitle because the title graphics of megaman 2 are so epic anything that distracts you from it ruins the effect.

I found a glitch.  I cleared all 8 robot masters and saved.  Loaded and it sent me to the wily cutscene as it should.  I saved again, loaded again , and suddenly 4 robot masters came back.

Pretty awesome.  Alex kidd should also get redone graphics for the master system that game always needed some better graphics to go along with the nice gameplay.

Indeed, but the only hackers on this one are aishsha and myself. I'm just acknowledging the script contributions for this particular video.

That's still a big part of the work and they're talented in their own ways.  Anyway since I'm posting here:

So far I'm up to world 6 and it's working great.  There's only one very minor issue where if you save and load just after beating a world once you beat the first stage of the next world you see the end cinematic of the current world for some reason (but you still have to play through it).  It's not a big deal so I'll leave it in for kicks, it doesn't let you skip any levels.

Probably to cut costs, a la Metroid. Although Metroid had a SNROM chip, it just didn't have the save battery.

Did metroid come with a ram chip and was just lacking the battery / diode circuit?

*looks at the pcb pic on nescartdb*

You know the Japanese version had saving originally?

Really?  I had no idea.  Why would they remove the saving feature in the american release?

Could be hardcoded pointers, and the three bytes are actually control codes (for text positioning/scrolling text).

Thanks for the explanation.  I've only dabbled a small amount in text hacking as I'm too impatient to make fanslations.

« on: February 22, 2014, 10:04:28 pm »
To make the gb colorizer code word I learned to write v-blank waitloops.  I actually can't remember the exact code but you can find it in those hacks.  Duodream (very cool guy) who I met on irc was kind enough to explain it to me.  Vblank really annoying to work with.

Ninja Rahoi translation preview. Got a bunch of help from Ryusui, Gid, Zynk, M-Tee et al for the fish puns.

Pretty cool, great team of hackers working on this for sure.

Some games are weird.  The main menu for fire 'n ice had the text stored in ascii that represents text so no table file needed to be made.  It was done pointer style with 3 hex values in between menu options to signify where the next line begins and the last one ends.  For some reason expanding the middle option beyond 4 text characters and moving over the next line code caused the game to crash.  Instead of figuring it out I just kept the text limited to 4 characters.  I guess for games that aren't very text heavy there isn't as much flexibility with the software.

« on: February 22, 2014, 08:05:08 pm »
I decided to test my new found nes asm skills that I gained from working on other projects.  I worked last night and this morning and hacked in fully functional sram saving to the fire 'n ice rom:

For something done in a night and a bit of a morning I'm pretty proud.

That it is. Notes are always appreciated. Otherwise what does the community have to build on?

It's amazing how much time and effort you can save just by reading through documents posted by other romhackers.  A lot of the information you'd need is out there you just need to take the time to read it all.

I think the best romhacks are ones that the author keeps taking it further and further.
