Parts of the 'O' were used twice in the original title.  Now that you've changed it, you've got two 'A's that could share the same tiles. Just a suggestion.

If you look at the PPU viewer, you'll notice that there is virtually no extra space.  The developers said "Hey, look at that, we have two 'O's! Let's just draw the tiles we need & reuse them." & so they did that.

However, bad news for you, since you're redrawing the tiles, this causes a minor dilemma.  But lucky you! You have two 'A's & only need to draw one, assuming you want them both to look the same.

Assuming you do, you can rearrange the tiles on the screen, which we'll gladly help you with, so that they display the redundant tiles (the 'A' tiles) accordingly.

But assuming you don't want to have the same two 'A's, you must find a way to fit some extra tiles in that 16x16 tile screen.  That's why I asked if you needed that "That's paradise" kana text.

Does that help?

Okay, first of all you need to find the tile data in a hex editor.  Do you have a hex editor? If so, see if it has a search feature.  If not, download one.  Personally I use Translhextion, but some other users on this board may have other suggestions.

Check the 'Utilities' section on the left for one.

Cool, search this string:

00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 04 05 06 43 44 45 46 47 48 46 4A 4B

You may need to omit the spaces, & that second to last '46' is just a guess, if it doesn't work, search up to '48' instead.

Great! You understand what we did, right?

Sorry to blow you off, but of all the nights I have something to do it's tonight! \

Here in Escondido we have this thing called 'Cruis'n Grand' where we can see all sorts of classic cars lined up & driving through the street.  I'll admit, I'm not into cars all that much, but I'm a sucker for the oldies.

What you do now is determine where the rest of the tiles are, which shouldn't be hard because you just found where it starts.  I'll be back another day if you need help.

Sorry for the double post but you have to see this:

I change the look of my code by specifying formatting.. For example:

Original Rockboard's code:

Title screen

First row:

01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 04 05 06 43 44 45 46
47 48 46 4A 4B

Second row:

10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 50 15 16 53 54 55
56 57 58 59 5A 5B 6C 6D

Third row:

20 21 22 23 24 25 26 27 28 29 2A 2B 2C 2D 2E 2F 24 25 62 63 64 65 66
67 68 69 6A 6B

Megaboard's code:

First row (I change it):

01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 07 08 09 43 44 45 46 47
48 46 4A 4B

Second row (I change it):

10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 17 18 19 53 54 55 56
57 58 59 5A 5B 6C 6D

Third row (I change it):

20 21 22 23 24 25 26 27 28 29 2A 2B 2C 2D 2E 2F 27 28 62 63 64 65 66
67 68 69 6A 6B

I do not understand:

The original game had 2 "O"s. The original game probably reused some parts of the "O" in ROCK to build the "O" in BOARD. You'll need to replicate those tiles and enter them into the tilemap.
