Title: My Next Project: Super Mario Bros. 2 - Special Edition
Post by: RetroRain on April 26, 2015, 01:30:10 AM
Megaman II Arcade was the next project on my list, and I want to do it, but I'm not feeling the spark at the moment.  I need that drive to go ahead and do it.

So instead, I'm going with the project that I do have the spark for.

My next project, which I will be starting real soon, is a hack of Super Mario Bros. 2 (USA), called Super Mario Bros. 2 - Special Edition.

DETAILS OF THE HACK:

• 2-Player Mode

For the first time, you will be able to play this game with 2 Players.  At the end of the game, when it shows how many times you used a character, if you are playing a 2 Player game, it will show how many times Player 2 used each character.

• Save System

After completing each level, the game will save your lives, how many times you used a character, the coins you collected, and the completed levels, for both players (whether it is a 1P or 2P game)

• An Extra World

The last world, World 7, will now be World 8, and a new world will be created for World 7, with 3 brand new original levels.  One of the new levels may have rain weather effects, and a green swamp level.

• The original snow levels might have snow weather effects in them.

• Fix the animation issue that exists in the original game (where not all values from the table are read)

• Titlescreen Features:

· 1 Player Game
· 2 Player Game
· Casino
· Sound Test

• For either 1 Player or 2 Player Game, can choose NEW GAME or CONTINUE.

• Upon completing game, titlescreen will be blue instead of red, and you will have the option to choose any level to play on at anytime (so if you complete a level, you can choose the next one to whatever you want).

• And last but not least, 2 Player Mode will be fairier than in the other SMB games.  For instance, whoever wins a level, the next player gets a turn.  Same if player dies.  The next person gets to go.

REGARDING CASINO MODE

Casino Mode is simply being able to play the SMB2 Casino Game without having to worry about coins.  It is just to have fun with it.

TARGET RELEASE DATE: Friday, December 25th, 2015 (if not sooner)

For all I know, it could take longer, but that is the date I'm hoping to have this hack done and released.

So, what do you think?

I have a lot of motivation to do this hack.  My first 2 Player hack, with a couple of extra bonuses! :D

Would it be possible to port the underground music from the prototype, yet retain the original music to be used in other contexts (like the boss fortresses)?

I don't think i'll find many people that would like to play Mario 2 around here, but the rest is pretty awesome.

The new world, save system and level select upon completing the game are probably the most interesting for me, although I have to ask, What's the animation issue you talk about?


One more question... Are you going to change something in Mario Bros or it will be the original game?

It'll be fine either way, I'm just curious seeing all the other changes.

SMB2 has eight frames of background animation, but whoever coded the sequencer typed #26 instead of #27. As a result, only the first seven frames are shown.

As a result of that programming mistake, these unique frames of animation go unused:

Wouldn't there be issues with distributing that?  Or are you going to make a custom patcher that will require a Mario Bros. ROM in addition to an SMB2 ROM?  Or are you going to create a clone of Mario Bros. using the same engine?  (That's ambitious, to put it mildly.)

I will not be touching the music, because I am music illiterate.  Otherwise I would have put music on the bootup screen of Megaman Origins, and a sound effect for when Megaman shoots at the screen.  Hence, I can not program something I don't know anything about.

No, there will be no problems distributing that.  I checked out the Mario Bros. ROM.  The ROM only has one 16K PRG-ROM bank, and one 8K CHR-ROM bank.  Which means, it can be easily added to the SMB2 ROM with no problem what-so-ever.  You just copy all of the bytes in the ROM (with the exception of the header), and paste it into a free space bank in the SMB2 ROM.  Since Mario Bros. only uses one CHR-ROM page, all I have to do is copy it and paste it at the end of the SMB2 ROM, and I might have to add a few lines of code to the Mario Bros. ROM to get it to read the correct CHR-ROM page.  It really is a piece of cake.

I already made a multi-cart hack, Megaman Origins, which demonstrates that you can have two games on one ROM file.  You can see it here: http://www.romhacking.net/forum/index.php/topic,19618.0.html

Mario Bros. is the smallest ROM I have ever seen.  This is going to be a walk in the park. :)

I think what the original poster meant was that wouldn't there be legal issues with distributing it. Usually, the idea behind a rom-hack and a patch it that you are only distributing you changes which do not include any of the original copyrighted material, thus skirting the piracy laws. However, what you're suggesting here would include all of the Mario 1 codebase (and copyrighted assets), which would thus be the same as distributing a rom.

In short: there's no sense in even pretending to bother with a patch, since you're giving away the whole rom anyway.

You're absolutely right.  I had not considered this before, and feel like an idiot for not even thinking of it.

In light of your reply, I have taken down the patch to Megaman Origins, and I will not be including Mario Bros. in this hack.

Thank you for the information.  I appreciate it.

Just curious, which version of the Mario Bros. game were you using before you decided not to put it in the game? The original release, or the Europe-only Classic Series version that keeps the demonstration scenes from the Arcade version among other differences?
Title: Re: My Next Project: Super Mario Bros. 2 - Special Edition
Post by: RetroRain on April 28, 2015, 01:44:25 PM
There was a ROM that said (World) on it.  So, the one that wasn't the Europe one I guess.

It's kind of a neat idea.  Like I said, you could write a custom patch program that takes as input an SMB2 ROM and a Mario Bros ROM and combines them appropriately, or alternatively a program that will generate a suitable IPS patch for SMB2 when provided with a Mario Bros ROM.

What about maybe using enough stuff from smb2 that it doesn't qualify as copying the Mario bros ROM?
You'd have to research what would bring it to a legally acceptable level, but, you know, use the smb2 chr sheets (it could be princess and toad instead of Mario and Luigi, and they could be fighting shyguys, etc). I don't know what else you could/would have to do, but you get the idea...

Nevermind. I just read up on the topic briefly and the impression I get is that there is no such thing as "altering it enough."
Too bad. It was a cool idea.

Post by: RetroRain on May 01, 2015, 01:11:52 PM
More SMB2 SE stuff:

• I thought of another idea for my hack. When I was a kid playing SMB2, before I knew how it was even possible for a game to run to begin with (how did they get all of that onto the cartridge? :P), I always wondered what would happen on level 1 if the player was able to go through that door at the very top of the screen. Now one would obviously assume nothing (it's just a door to illustrate that the player has entered the dream state), but as a kid you used your imagination and wondered what would've happened if you could go through it. At least, I did.

I was thinking of doing something with that in this hack. Perhaps if you find a secret way to go through that door early on, the game ends early (ending the dream).

• Now, I thought of who the boss is going to be for the new World 7. It is going to be Wart. You will face Wart on 7-3, and when you beat him, he will display a message on the screen "COME TO MY PALACE IF YOU DARE." You will then go to World 8, which is the original game's World 7. And then you will fight Wart for the final time.

I will have to add checking-code so that the game will not take you to the ending unless you are fighting Wart for the second time. And this makes even more sense by the fact that I wanted to have a rainy green swamp level. So Wart's "home" as you could imagine is in a swampy area (makes sense right? ;)), and when you defeat him there, he flees to his palace.

Also, I tried to get Megaman Origins taken down from RHDN, and they are apparently not going to take it down because they don't see a problem, so I'm still considering putting Mario Bros. in this game.

You still have to use a second-hand utility like Lunar IPS to patch the data to the ROM, so I don't think it would be a problem.
Title: Re: My Next Project: Super Mario Bros. 2 - Special Edition
Post by: chillyfeez on May 01, 2015, 04:00:33 PM
I guess if RHDN doesn't think it's a problem...
As the distributors of the patch, it'll be their asses on the line far more than yours, anyway.

And yes, yes, a thousand times yes. I was convinced as a kid that their had to be some way to get through that door.

I played this thing time after time as a kid, and I always tried to "enter" by pushing up all the time when you start the level, or trying to get up there...

It seems that RHDN has finally taken down my Megaman Origins patch.  It took a lot longer than 24-48 hours.  I wonder if they were taking a look at the ROM after using the patch?

Yeah, so to play it safe, I'm going to keep Mario Bros. off of SMB2, as much as I really wanted it on there.  If people want to play Mario Bros., they are more than welcome to get the game.

I felt that because SMB3 had a Mario Bros. type of mini-game on it for 2 Player mode, that since I was doing a 2-Player hack of SMB2, Mario Bros. seemed like a fitting bonus game to be able to select on the titlescreen, and at the same time made this hack another multi-cart hack.

For the first time, you will be able to play this game with 2 Players.  At the end of the game, when it shows how many times you used a character, if you are playing a 2 Player game, it will show how many times Player 2 used each character.
And I think: "Oh, yes! At least I'll be able to play this game at the same time with a comrade! So cool! My childhood dream becomes real at last!"

But then...

"NoOOOOoooOOoo! It's the regular old fashioned 2-Player mode! Why...?!"

Anyway, it still seems like a nice hack including that extra world and all that. Can you show some screenshots or will it be a surprise?
Still haven't found a way to implement Mario Bros. as a patch? Is it definitely discarded?

How hard do you think it would be to implement a realtime 2-Player mode? Is it technically reasonable?

What's the problem with taking turns playing in 2-Player mode, whether you win or die?  It really is the most fair.  I remember playing SMB1 with my older sister when I was a kid, and we played 2-Player mode.  She got annoyed at me because I kept beating each level, and she never got a turn to play.  And she had a point.  What's the point in playing 2-Player mode if the winner gets to keep going until he or she dies, and the other player never gets a turn?

In all honesty 2-Player mode would be more fair and probably a lot more fun if both players get to go along with each other, instead of one of the players falling way behind, or taking a while to get a turn.

Quote from: SC on May 04, 2015, 05:33:38 PMAnyway, it still seems like a nice hack including that extra world and all that. Can you show some screenshots or will it be a surprise?

I will be showing progress of the hack as I go. :)  I'm even considering making a Development Blog thread soon, to show some of the code I'm using, and what part I'm at on the project.  Screenshots will be shown when there is something visually to be shown.  Right now I'm doing a lot of the pre-work (setting up the ROM and bootup screen).

Quote from: SC on May 04, 2015, 05:33:38 PMStill haven't found a way to implement Mario Bros. as a patch? Is it definitely discarded?

Yes.  I truly truly wanted it in there, but for legal reasons, I've decided to leave it out.  I'm playing it safe.

What do you mean by "real-time"?  Do you mean both players on the screen at once?

I am definitely interested in this. There just are no real quality SMB2 hacks that I've found. I played the only one that was finished as far as I could tell, and it was difficult to say the least. I don't see any point in these RIDICULOUSLY HARD Mario hacks. I love SMB as a series and I want to play a game that is similar to the originals, not custom built so that only the programmer can beat the damned thing. I played "Newer" SMB Wii at my friend's house in Kentucky and I was like "Now THAT is how its done". I'm very intrigued by the new level being added, and I wish I had gotten your Megaman Origins game before it got pulled b/c that sounds really cool. Were you originally going to put MM3 on that compilation? My same friend was telling me about a combined MM1 and 2 rom file that was supposed to be really good. Would love to see some screenshots too.

I don't know about any other combined MM1/MM2 ROM other than the one I did.  Your friend was probably referring to my Megaman Origins hack.  This is the thread:

http://www.romhacking.net/forum/index.php/topic,19618.0.html

The only new screenshot is the bootup screen, which allows you to select either game.  The other screenshots are taken from the actual games.  And yes, if all 3 ROMs used the same graphics format, I would have made this Wily Wars for the NES.

Legend of the Blob Bros 2 is pretty neat, especially some of the later levels.  (Note that you will, at one point, have to balance a mushroom block on a cloud.  Apparently that works in the original game, but as I was completely oblivious to that, I thought the game was broken at first.)

Ya know, that's not a bad idea.  Given how much room there is on the Game Over/Continue screen, I might be able to add an image or something.

How cool would it be to make the Game Over screen just like in Zelda 2?  A shadow of Wart appears on a red screen, and you hear some kind of sound?

Or Mario in bed waking up, and instead of the dream cloud showing the four characters waving, it shows Wart destroying something, or jumping up or down.

Sounds promising. Please include a mode where you don't bump into each other in co-op, and please don't make the game pause when someone picks up a power up or dies. :)

Edit: Oh, you didn't mean simultaneous 2-player, my bad.

Do you consider the original game to be pretty much perfect in terms of mechanics and level design? I think you could improve on a lot of things.

One neat idea you should do for your hack is for the levels that have caves. When you go in them instead of playing the normal underworld theme, it plays the prototype underworld theme.

For the levels that have dungeons. When you go in them, the normal underworld theme will be played.

Will this hack feature some of the fixes from the Mario 2 De-Engrish Rewrite hack?

How about a DDP mode?
Where the game stays true to Doki Doki Panic, where the challenge of the mode is complete the game with each character

As a person that plays games almost exclusively as two-player: Level or Death with joint progress is my preferred method. Otherwise the game becomes unenjoyable for players of differing skill levels.

This. Super Mario Bros 1 would always annoy my siblings that weren't as good as me so they would purposley try to get me to die so they could play. Super Mario Bros 3 at least got it right.

How about a new intro screen in the same vein as Doki Doki Panic?

There is no way to make a patch that requires 2 roms?
Or 2 patches

Not a standard patch, no, but there's always a way.  You could write a program that uses one ROM to generate a patch for another ROM.  Of course, you'd probably have to make the source available so that people who don't have a Windows PC can still run the program if they want to.

OMG  This looks and sounds amazing, did you abandon the game project?  This was always a dream come true to me, to have this as 2 Players and added features..  Please dont give up!

I'd like to see pics or video of the 2 player mode.

No, this project has not been abandoned.  It is merely on hold, and scaled back because of time and workload.  It would be a Two-Player hack with SaveRAM functionality.  The Free Casino, Sound Test, and the extra world have been scrapped.

The project already has the two-player functionality in it.  I would have shown a video of it a long time ago, but until I did some extra programming, you wouldn't really be able to tell from a video.

In the meantime, I have released a Standard Mario Patch for SMB2.  You can get it here: http://www.romhacking.net/forum/index.php/topic,23659.0.html

There is another method of doing two player; a tag out system.  I already have an incomplete instant character switching thing so I'm sure that's at least possible.  Consider making this an alternate mode!

I'd love to see a two player hack of SMB2! Are you still working on this?
