Goddamnit, I can't remember how I did it. XD
All I know is that you gotta take into account the tile ID, which should be the same tile numbers that each 8x8 tile has under the PPU Viewer, and the other info should be the data in the PPU Viewer at the Name table viewer.
Let's try a different method though...
Ok first off, pause the game at the EXACT time you can see almost the whole overlapped tiles in the flashing sequence and go over to the PPU viewer under "Debug"
You shall see the tiles that are being used at the moment that you paused the ROM, and some of those should be your title screen tiles.
Check the tile ID for the tile that has the first half of the letter "D" (the one at the very right) AND the tile ID for the white line next to it, the one that is a part of the white square surrounding the title screen. Should be something like F8 (in my hack it is F8).
Now check the tile ID for the rest of the D and the "RACULA'S CURSE" tiles.
WRITE THEM DOWN.
Now go to the HEX Editor included within FCEUX, go to File-> ROM File.
Remember the Tile IDs for both the first half of the letter D and the white line?
Now open up the Find option within the Hex Editor and type the two HEX valuesNEXT TO EACH OTHER from the TIle ID you got from those.
Select "Hex" so that the Finder searches for HEX values and click FIND NEXT (or enter).
You should now see something like "(HEX value for the first half of the letter D) F8" followed by something like a 00.
After two or three HEX values after the F8 (white line tile ID) you should start seeing that the rest of the "RACULA'S CURSE" tile ID hex values are being written NEXT TO EACH OTHER.
For example, the top part of the number "III" in my hack is "A2 A3 A4 A5", and you can see them right next to each other in the ROM data.
THIS is how you can replace how the tiles are being written in order.
This is one way to do it (and the easy one at it).
Let's hope this helps you to try to change the order of the tiles in the flashing sequence.
If you have doubts, let me know.
