NES Rom hack help!!

[ManPeace]

Hi I am new to rom hacking and am trying to change the graphics from Teenage Mutant Ninja Turtles III: Manhattan Project. I am using tilemolester currently trying to simply change one of the sprites. I changed it in photoshop and cut and pasted it back into the program but the program made it look weird. Is there an easier way to change the sprites? And is there a program that will arrange the sprites for you? Also I was wondering how when creating graphics does one deal with the issue of the palette. Should I worry about this when creating graphics in photoshop?Thanks so much for any feedback!

Since every game is different there can't be a program that gives you the sprites the way they appear in the game unless it's a game specific utility.

The way the images are stored in the rom means that rather than each sprite having its colours, it has 4 shades (one of which is transparant). The other 3 shades are assigned by the palette.

I changed it in photoshop and cut and pasted it back into the program but the program made it look weird.

What exactly do you mean by weird? A screenshot could possible help to identify what the exact problem is. How exactly did you cut & paste it back in? Did you do a literal cut (from Photoshop) and paste (back into Tile Molester)? Or did you use the Paste From option in the Edit menu? I'm going to make a guess that your problem stems from the number of colors saved in your edited file. In Photoshop, try setting your color index to 4 and then save the file as a BMP or GIF and try importing that into Tile Molester and see if it helps.


Is there an easier way to change the sprites?

The easiest way would probably be to do it directly in Tile Molester.



And is there a program that will arrange the sprites for you?

By playing with the block size in Tile Molester, you can usually get the sprites arranged to look as they appear in the game, though it often takes a lot of trial and error.


Also I was wondering how when creating graphics does one deal with the issue of the palette. Should I worry about this when creating graphics in photoshop?Thanks so much for any feedback!

Check out Toma's document about pallette hacking to learn about how to change the colors. Basically, the colors are completely disconnected from the actual graphics. (A good example of this is Super Mario Bros. The graphics for Super Mario and Fire Mario are identical, only the pallette is changed.)

A ROM hack for class? o_O
Damn, why couldn't they have had that kind of class when I was a kid?

I use TileEd 2002, the emulator FceUxd SP and Hex Workshop (a hexadecimal editor).

TileEd lets you find the tiles that make up the graphics of the game and edit them.
FceUxd SP has a debugger, lets you see the game tiles, pallets and has many options to help you change the graphics of the game.

I look to see if I can find graphics, tiles or any information about the game and if I find I can post.

You can download a small tutorial, but not is complete to change some things of this game:

The modification is very simple. Only change "KONAMI" and put "MAN PEACE" in the screen menu. I uses Tile Molester and "Adventure Island 3" (NES). I put the letters of the "Adventure Island 3" but you can modify the graphics with "Brush" and "Dropper" of Tile Molester.

I am trying to convert the nes graphics I made to work properly back in the ROM but am having troubles. I am using tile molester and trying to figure out bob rosts bmp2sprite but cant get it to work. Is there another program that will format the graphics for you or can someone give me a walkthrough for getting a file into bmp2sprite using terminal and having the program spit out the correct nes file? thanks so much! http://bobrost.com/nes/resources.php There must be an easy way to convert the BMP to the NES jumble format right???

Note from Lillymon: This post did not require a new topic, please just make a new post in your existing topic if your new request is so closely related to the old one.

thanks so much for your in-depth help. I am still having trouble finding a simple way to import my modified BMP back into the rom so it will look right. I tried bob rosts bmp2sprite but cant get it to work for me. I am trying to modify the main graphics in the title screen as shown above. I understand how to switch the konami logo but the manhattan project one is huge and difficult to put the puzzle pieces together and then get them back in there. Is there a way to automate this format? or an easy way to coordinate the tiles with the ones you want to replace? I really am in a jam here. thanks
