Sega Arcade sprite interleaving problem - AFruitaday! - 08-09-2019

I want to rip sprites from Holosseum, I already know that the sprites don't show up in the MAME tile viewer. I found the sprites in TiledGGD, and I know to interleave it in order to rip it fully but this game has 8 sprite files, interleaving them is such a nightmare! Can someone help me how to interleave these sprites. How do I determine to interleave the sprite files in other games correctly?

First, open the command prompt and run this code:

Code:
mame64 holo -listxml >> holo.txt

This code will save a bunch of information about the ROM in the holo.txt file. Open the file and scroll until you find this section. I removed the sha1 for readability:

Quote:<rom name="mpr-14973" size="1048576" crc="b3c3ff6b" sha1="" region="mainpcb:gfx2" offset="0"/>
<rom name="mpr-14972" size="1048576" crc="0c161374" sha1="" region="mainpcb:gfx2" offset="1"/>
<rom name="mpr-14971" size="1048576" crc="dfcf6fdf" sha1="" region="mainpcb:gfx2" offset="2"/>
<rom name="mpr-14970" size="1048576" crc="cae3a745" sha1="" region="mainpcb:gfx2" offset="3"/>
<rom name="mpr-14969" size="1048576" crc="c06b7c15" sha1="" region="mainpcb:gfx2" offset="4"/>
<rom name="mpr-14968" size="1048576" crc="f413894a" sha1="" region="mainpcb:gfx2" offset="5"/>
<rom name="mpr-14967" size="1048576" crc="5377fce0" sha1="" region="mainpcb:gfx2" offset="6"/>
<rom name="mpr-14966" size="1048576" crc="dffba2e9" sha1="" region="mainpcb:gfx2" offset="7"/>

This section tells how the graphic files are loaded. In this case, each file loads 1 byte before looping until the end.

mpr-14973 moves 1 byte to 0x0
mpr-14972 moves 1 byte to 0x1
mpr-14971 moves 1 byte to 0x2
...
mpr-14966 moves 1 byte to 0x7
mpr-14973 moves 1 byte to 0x8
mpr-14972 moves 1 byte to 0x9

Now you just need to write a script to do this, I recommend Python. I'll also link a video that has a better explanation and has an example code, it helped me a lot when I was ripping Taisen Hot Gimmick: https://youtu.be/jP-j4F-X9RM

Thank you so much! Now I can find both the graphics and palette! And understand how to interleave them correctly!

But wait, what do you mean by creating a script on python?

Write a script using Python to interleave the files. This is just faster for me but if you know other programming language or software that interleaves, use it.

I know Notepad++, can that interleave the files?

RE: Sega Arcade sprite interleaving problem - AFruitaday! - 08-10-2019

oh ok then.

RE: Sega Arcade sprite interleaving problem - AFruitaday! - 08-14-2019

Ok, now I got python downloaded, what script should I write?
