I have a topic for our graphics experts here on the board. The team members and I've been trying to edit the title screen menu options of Namco X Capcom. However we can't get it to work good. The graphics shows up fine in Tile Molestor - but the colors are messed up. Some screenshots: How it looks like in the game  2D - 15Bpp  2D - 32Bpp  Gemini said 15bpp is the correct color depth, to me subjectively 32bpp looks better, I just don't have the experience with graphics to really know what I'm talking about though. Also note how the gfx seem doubled in 32bpp. Shouldn't they be squished to half in comparison to 15/16 bpp instead? Well, I don't know what to make out of this, I'm grateful for all help, information and hints  This is a crude test Saito made. He changed one of the lines directly in Tile Molester using only one color (in 32bpp mode if that matters):  The colors look ... interlaced? Maybe this can help you. Also, here is a link to the file containing these graphics: http://download.yousendit.com/435B6E2005E62950It only contains the graphics pertaining to the title screen. Thanks in advance. |

... These seem to be similar to TIM files. I can see the palette entries in Tile Molester, but for some reason none of my TIM programs will do anything with the file...
Edit: Tried increasing the size of the grid by pressing Shift + Right arrow?

We also tried all Tim programs, no luck. Maybe it's a custom tim format?
Using shift+arrow keys didn't help either. It made the image more drawn out or narrow, but the colors stayed the same.

in the 2D - 32Bpp it seems each word is composed by two images interleaved. The one in the middle an the other that is devided by the edges. Maby that's why the 2D - 15Bpp Fonts seem squashed and the text appear's interlaced in the modded image

right, 15bpp (or maybe 16bpp, i dunno) is definitely correct. you will want to edit that, and it should look right. is there a palette, or are the colors just RGB encoded in a weird way, or what?

There is no palette afaik (as it's a bitmap with 15bpp a palette would be quite insane), I guess it's really weird encoding.

It does have a palette. Those little blocks before the image? I've seen TIM files that have that, so I'm fairly sure that's the palette. |

Guys, 15+ bit images don't need any palette, 'cause they are palette themselves. That block of data just after the image is supposed to be some kind of header (probably width and x-y position in vram), so nothing to do with palettes.

The 32-bit mode expects twice the data of a 15/16-bit mode, so its number-of-bytes-per-line is doubled. When your data has only half of that, the 32-bit mode puts two lines of source data into one visible line.  About the format - there are several possibilities: 0RRRRRGGGGGBBBBB RRRRR0GGGGGBBBBB RRRRRGGGGG0BBBBB RRRRRGGGGGBBBBB0 0RRRRRBBBBBGGGGG RRRRR0BBBBBGGGGG RRRRRBBBBB0GGGGG RRRRRBBBBBGGGGG0 0GGGGGRRRRRBBBBB GGGGG0RRRRRBBBBB GGGGGRRRRR0BBBBB GGGGGRRRRRBBBBB0 0GGGGGBBBBBRRRRR GGGGG0BBBBBRRRRR GGGGGBBBBB0RRRRR GGGGGBBBBBRRRRR0 0BBBBBRRRRRGGGGG BBBBB0RRRRRGGGGG BBBBBRRRRR0GGGGG BBBBBRRRRRGGGGG0 0BBBBBGGGGGRRRRR BBBBB0GGGGGRRRRR BBBBBGGGGG0RRRRR BBBBBGGGGGRRRRR0 Have you tested all of them? EDIT: And 16-bit modes of course, too: RRRRRRGGGGGBBBBB RRRRRGGGGGGBBBBB RRRRRGGGGGBBBBBB RRRRRRBBBBBGGGGG RRRRRBBBBBBGGGGG RRRRRBBBBBGGGGGG GGGGGGRRRRRBBBBB GGGGGRRRRRRBBBBB GGGGGRRRRRBBBBBB GGGGGGBBBBBRRRRR GGGGGBBBBBBRRRRR GGGGGBBBBBRRRRRR BBBBBBRRRRRGGGGG BBBBBRRRRRRGGGGG BBBBBRRRRRGGGGGG BBBBBBGGGGGRRRRR BBBBBGGGGGGRRRRR BBBBBGGGGGRRRRRR |

Tile Molester only supports RGB and BGR, I have no idea how to test the other variants  \ |

With your own self-programmed tool? :thumbsup:
*sigh* Maybe I could code a little viewer...

It looks like the image is 8bpp with a palette before each section. Here is the 8-bit image with no palette applied.  |

One plus two plus one plus one. Dammit, I should've seen that. It makes perfect freakin' sense. -_-;

The "Namco X Capcom" logo is definitely 15- or 16-bit though. (xres=512) |
