Super Robot Wars 64 Retexturing (mechs & characters)

* This is all meant for use with Nemu64 0.8 along with the Rice's Video plugin
Nemu: http://nemu.emuunlim.org/
Rice's Video plugin: http://www.zophar.net/utilities/n64gpuplugins/rice-s-video-plugin.html

** You *must* select the Rice's Video Plugin in Options -> Settings...

*** All of this is to be applied on stage 01, Male Real (Arklight Blue) ***

Changing the ID of the closest enemy unit (up to the left):
1) Attack the unit first with the machinegun. Hopefully it will have 497 HP left and you'll be able to see its stats (pushing A twice on the enemy unit). Save the game after this (unless you want to go through the presentation again the next time...)
2) Go to Plugins -> Debugger: Memory...
3) Go to this address: 0016D0fe
4) The value for the unit's ID is the "0117" (the second half of the first double word you're shown, on the top-left)
5) Modify said value to get a different unit (0001 gives you the God Gundam, 0002 the God Gundam with open backpack, and so on)

* After changing the unit's ID, you won't see any change in the unit if you were already seeing its stats. Just close the stats window and reopen it.

------------------------------------------------------
Changing your main character's ID
* Same as above, but the address for the character's ID is 00172F42 (the value you have to change is the "0019")

------------------------------------------------------
Dumping the textures:
1) Go to Plugins -> Configure Video Plugin... (or press F12)
2) Under the "Texture Enhancement" tab, select "Dump textures to files" on the lower-left
3) From that moment on, every new textures that appear will be dumped into <Nemu folder>/Plugin/texture_dump/½°Êß°ÛÎÞ¯ÄÀ²¾Ý64 (or probably the game's name in Japanese if for any reason it shows properly for you)
4) You'll get 5 different folders for dumped textures, go to the ci_by_png one.
5) Order the files by date. That way you'll see on top the newest generated textures.
6) Save the set you want to another folder.

* A set of textures for a unit or portrait shouldn't have more than 9 textures, but can have less than 9 if one of its pieces is empty.
** DON'T CHANGE THE NAME OF THE TEXTURES!!

------------------------------------------------------
Modifying the textures:
* You can put anything you want in the textures, as long as you respect the proportions. That means the textures' width and height should *at least* be the same (100x100, 200x200, etc.)
* I haven't tried otherwise, but I'd recomend these textures to be proportions of the originals. For example, portrait textures are 32x32, so the retextures could be 64x64, 128x128, etc.
* If you have an image you want to use as a portrait/unit texture and need an easy way of splitting it into the 9 (or less) pieces needed, here's how to do it in GIMP:
1) Go to Image->Guides->New Guide...
2) Select the position in pixels for where you want the image to be cut, either horizontally or vertically.
3) You want to add four guides, two horizontal and two vertical at 1/3 and 2/3 of the image.
4) Go to Image->Transform->Guillotine
5) The previous command will create 9 new images with the pieces you just cut. Export them to png files with the name of their corresponding dumped files and you're done.

* Note that the textures won't show properly in game, as you can notice the seams between pieces. This is most probably an issue with the graphics plugins.

** A solution to this, by Bring Stabity:
Do this: Take the old sprites and toss all 9 of them into GIMP. Arrange the pieces together as if you were gluing them together. Measure how many pixels of overlap there is (simple solution is to turn down opacity to 75% and the stuff that is solid has an overlap). On your new picture make the guides. Copy the center box to another layer and export it. Then manually make selections that overlap with the center image by your scaling factor times the original overlap in pixels, copy to another layer and export. It'll take longer, but that's how you avoid the seams.

*** An example of what Bring says about the seams can be found here:

(notice how the layers around the center one had to be displaced for the image to be aligned)

------------------------------------------------------
Loading the textures:
1) In the "Texture Enhancement" tab, enable the "Load hi-res textures if available".
2) You'll have noticed that the folder <Nemu folder>/Plugin/texture_dump/½°Êß°ÛÎÞ¯ÄÀ²¾Ý64 has been created when you start the game with the "load textures" option enabled.
3) Create a "ci_by_png" folder inside (not sure if necessary).
4) Place your modified textures inside.
5) Start the game.

* Any N64 emulator using the Rice Video plugin can load the textures this way. I just used Nemu because of the memory editing feature. Enjoy.
