Do you have examples of what you're doing?
Title screen shots, example data?

The tiles, and the Title screen that I wanna alter it, and all the item lists.
I want to hack the title screen first and than, I wanna rename all the items (Or Gadgets from the future) from Japanese to English.
For Example, Dorayaki to Yummy bun.
So, tell me how to change the Title screen and tell me what 's the name of those gadgets in English?

What are the relevant offsets? What logic do you use when you try to change the tiles? Are you trying to change the graphics themselves or the placement of tiles on the screen?

Well, you first need to resize your English graphic and make it use three colors like the original Famicom graphic.

And... I think you realize it already, but the title screen's different pieces (tiles) are scattered in the ROM (you can see it in the PPU Viewer window of the FCEUX emulator) like you found out.
which means you'll need to either:
a/ insert the new title respecting the original arrangement (so, you'd use Crystaltile2's tile composition tool and reconstruct the title like seen in-game, export, modify that image in paint or whatever than reinsert it).

AND/OR
b/ modify the arrangement of the tiles (what we call the "tile map") to better suit your new title.
Emulators like FCEUX (Name Table Viewer) or NO$SNS for Super Famicom (VRAM Viewer) among others... offer tools to see what this arrangement is like.

One easy way to find the tile map for NES games would be to make a second ROM where you replace the part appearing in the PPU from the graphics with an image like this, where each tile has its index written inside.



example



You get results a lot like this:



>



(You're not supposed to insert ALL of the "guide image" tiles, you may just put the ones for the first few lines and leave the rest alone if that's where your title screen graphics are. The reason why the whole screen looks liek that is that the "blank" tile repeated for the empty parts of the screen was also replaced by a numbered tile)

Now using a hex editor you can search for the tilemap data for that orange part of the menu, looking like "20 21 22 23 24 ..." (without spaces) in the hex data.

Note that there are cases where this doesn't work (notably sprites).
And, for SNES games, it gets a bit more complicated and tile indexes are followed by more info (if they are mirrored, etc) and I'm still a noob regarding SNES and GBA/DS tiles even though it could save my life for something I'm needing to get done right now.

Sky_Yoshi, I recommend you post your images like GHANMI has straight into the post as it is much easier for people to follow. Having to download a zip from an unknown location, virus scan it, unzip it, virus scan again and finally open to view is a bit annoying.

To post an image into the site, try using a photo-hosting site, like imgur or photobucket.
Upload the screenshot onto that site, then look under the links for a Direct Link. Copy that link and then paste into the post: [ img ] link [ / img ] (without spaces)
