| I'm working on my first ever hack, which is basically just a graphics hack of Super Mario Bros. 2 for the NES. I've changed the "Story" text at the beginning of the game without much problem, but I can't figure out how to change the character names in the game's credits. To change the other text, I looked at the pattern tables in NESticle to get the hex values of each letter, then went into translhextion and changed the hex values to make new text. Pretty easy. So I look at the pattern tables for the text in the ending. a = D0, b = D2, c = D4 and so on. I search for the misspelled word "clawglip," (D4 E6 D0 FC DC E6 E0 EE) meaning to change the "L" into an "R." (F2) But the search for D4E6D0FCDCE6E0EE doesn't turn up any results. I can't seem to find any of the words from the ending anywhere in the ROM. Admittedly, I'm very new to this and have little idea what I'm doing. Anyone have any idea what I'm doing wrong? Is the text compressed somehow? If so, how would I go about uncompressing it so that I can make changes to it? EDIT: OK, never mind. I figured it out on my own. Turns out there are three other hex values separating each letter, so searching for a solid string like that wasn't finding anything. (edited by icegoom on 06-29-05 12:24 AM) |

| For each level type in Super Mario Bros, there are three palettes that enemies can have. Above ground, for example, Goombas, Buzzy Beetles, and Bullet Bills share one palette, while Green Koopas, Pirahna Plants, Hammer Bros, and Lakitu share another one. I'm wondering if it's possible to change an enemy from one palette group to another one. Say I wanted to make Goombas red and share a palette with Red Koopas and Spinies. I know how to change the three palettes themselves, and I see where the data is for which tiles the enemies will be made from, but I can't find any data that seems to indicate which of the three palettes a specific sprite will use. Can anyone who's done this before point me towards what I need to change? |

| Bear with me, I'm very inexperienced with hex editing. I went into Transhexlation and typed 686b without the dollar sign. (Because Transhexlation didn't think it was a valid offset with the dollar sign in front) It took me to the middle of a row, to 07 followed by E8. I really don't know what to do with that, so I just tried changing 07 to 08 to see if anything would happen. I played through several levels and didn't see any enemies that had changed color. So then I tried changing the next couple of lines to all 00's and seeing if that would change anything. It didn't seem to have any effect in-game. So I guess I'm going to have to be stupid and n00bish and ask someone to tell me exactly which number I need to change to what in order to get results. |

| Ah, I needed to stick an "x" on the front of the offset. Everything makes sense now that I'm in the right place. I guess I really should try to find FCEUXD and learn how to use that. Out of curiosity, are sprites' palettes arranged in a similar way in other games, or is just SMB like this? |

| Hmm... the game froze up for me when I got to 1-3. I'm probably just using the wrong version of the game, though. What I saw consisted only of dodging firebars. I see Cheep-Cheeps and Bullet Bills in your screenshots, so I guess you eventually introduce other enemies. Are you going for a lifeless feel in the beginning?

| So, you guys sick of Super Mario Bros. hacks yet? Well, tough. Here's another one. My main project is a Super Mario Bros. 2 hack, but I'm having trouble getting the hang of the Discombobulator, so for the past few weeks, I've been working a SMB Hack starring Bowser as a side project. It has four worlds worth of brand new levels and almost entirely original graphics. The story goes like this: A band of Koopas had finally overcome Mario and were bringing him back to King Bowser. But on the way, Wario and his goons swept in and captured Mario and the Koopas. When word of Wario's brazen act reached Bowser, he was understandably outraged. He decided that he himself would storm Wario's fort, reclaim Mario, and then finally do the pesky plumber in. Screenshots:                 And you can grab the patch here. (That's got Stifu's new Bowser sprite. For comparison, the old hack as pictured is here) I used the version of SMB with the title screen to make this, but the no title screen version seems to work all right, too. This is the first hack I've ever released, so I hope that everything works all right. Let me know what needs to be improved graphics-wise and gameplay-wise. I might expand this hack to a full eight worlds, but then again, I might not. (edited by icegoom on 10-28-05 11:16 AM) |

| Thanks. The pipes are modified from Yoshi's Island, which is my favorite Mario game graphically. Has anyone checked to see if the patch works? I'm a little nervous that I didn't do it right. | |||

| Thanks. I've already got Wario as a playable character battling Bowser in my SMB2 hack, so I thought this would be a nice turnaround. The springboard myself I drew myself. The pipes are one of the few things I didn't draw from scratch. I'd considered making Bowser's fire fly straight, but didn't get around to implementing it. What I'd really like to figure out how to do is make it so that Bowser shoots fire by default, even when he's little. And then if he grabs two power ups, he gains the ability to throw hammers in addition to fire. It's probably not possible for him to throw two different types of projectiles, but that's my little dream anyway. (edited by icegoom on 10-23-05 03:22 PM) (edited by icegoom on 10-23-05 03:24 PM) |

| Hammers aren't a normal ability, but there's a patch out there that changes fireballs into hammers. Googie recently used it in his Luigi's Chronicles hack. There's probably no way both abilities could be supported in the same hack, though. | |||

| Ooh, thanks for catching those. I tested the levels several times, but I guess a few things slipped by me. All of those level glitches should be fixed now. I'm not familiar with the glitch that allows you to get stuck in 2-2, so I hope that taking away the wall extending above the pipe fixes it. Ugh, I can't believe I missed that you can get on top of 3-4. I hate getting stuck and thought I'd caught all those. With the spinies, my reasoning was that Bowser is a fiery creature, so touching an ice creature would be deadly for him. But yeah, they do kind of look like they should just crumple when he stomps them. I'll try extending their head crags a bit. I'll also fix the Cannons when I get time. |

| I spent quite a bit of time trying to get rid of the grey box, but it was beyond my skill to get rid of it. I'm sure it's pretty easy to get rid of, I'm just inexperienced at hex editing. I never was completely satisfied with the big Bowser sprite, but it was the best I could do. He's a pretty complex character to try to render into a 16 x 32 space. By all means, give it a shot. This is my best alternate:  |

| The enemies still move the same, but the new sprites move in ways that make sense. For instance, I always find it weird to see a Blooper flying through the air, so when I replaced it, I changed it into a Snifit with a jet pack on its back so that it would sort of make sense that it could move the same through sea and sky. I made the hack with the title screen version, but I tested it up to world 2 or so patched onto the no title screen version and it seemed to work fine. That Bowser sprite looks great, Stifu. I'm going to attempt to animate it and see if I can fit it into the game. I'll probably have to edit little Bowser a bit, too, if I'm going to change his palette. |

Put Stifu's Bowser graphics into the game. New patch here.    Is this preferable to the old? |

| Completely my fault, Googie. I fixed a few graphical errors and reuploaded it. Guess I screwed up making the new patch. Just redownload it and it should work this time. And yeah, I like your Bowser much better, too, Stifu. The line in question is just supposed to be the white rim around his shell:  His arm's usually blocking it from the side view. I don't really see any problem with it. |

| This game is great! I love running around as a fiery racoon. You didn't used to be able to pick up spiny shells, did you? The animations are really nice, especially the lava. | |||

| I'm really glad people are enjoying this hack. Has anyone played it through to the end yet? I tried to make it more challenging than the original, but not so hard that it could only be beaten with savestates. Thank you for the kind words, Vystrix. I certainly hope I can one day become as good as some of the great hackers around here. Final Fantasy would be fun to do. I've got some ideas I'd love to try out in an RPG, but I'm probably not advanced enough to attempt them yet. I'm currently working on a hack of Super Mario Bros. 2, which is one of my favorite NES games, and after that, I'd really like to try a Zelda II hack. |

| Gecko, try downloading it here. If that doesn't work, recommend me a site you can download stuff from and I'll try uploading it there. Stifu: Hmm... Looks like the lines don't quite connect on that frame. I guess I just need to add another pixel? |

| Try doing a google search for "Super Mario Bros (JU) (PRG 1)". That's the clean version of the ROM that has a title screen and should start properly in 1-1. | |||

| Oops! I'll edit that in right away. I don't think the problem is with mirroring. There are two frames for Bowser climbing, and I just didn't properly connect the line in one frame. I've considered lengthening the hack, but I probably wouldn't do the full eight worlds. I don't really like repeated levels. I also moved a lot of objects and enemies out of the later worlds into the earlier worlds so they wouldn't be so empty. (Especially 4-4) If you beat the game and use the B button to select a world after world 4, you're going to run into some glitched levels. (If I knew how to remove the option to select the later worlds, I would have) I probably have enough objects left to do two more worlds. |

So they do. I remember the duck frame being kind of hard to do since space was at such a premium. I kind of hid his far arm behind his head, too. Here, I tried fixing it, but it might have made his hand too small now: Googie: Yeah, I used SMB Utility. I already figured out how to use sort area to shuffle the levels around. (Level 3-3 is based on 4-3, for instance) I'm starting to mess around with some new levels now. Anyone know if it's possible to add another underwater level? I've seen other hacks that change water levels into castles or underground levels, so I guess it's just a value I need to change in a hex editor? |
