RomPatcher.js VS individual-color-variation

You need to patch your rom with the translation patch. On PC there's offline patchers, but using something like https://www.marcrobledo.com/RomPatcher.js/ is probably easiest on mobile.

In that case, you're gonna need a ROM, an emulator (https://www.zophar.net/snes/snes9x.html), a translation patch (https://forums.serenesforest.net/index.php?/topic/63676-fe4-translation-patch-open-beta-v7/#comments), and a patcher (https://www.marcrobledo.com/RomPatcher.js/). Theres different patches for different versions of the game, but the readme in the translation patch tells you which patch to use for your file.

Do you have a 3DS or PSP? I hacked mine and it’s really convenient to play old games on. There’s lots of homebrew tutorials on YouTube. For those games you need to put a translation patch on the rom (I usually use this website to patch stuff). Or sometimes you can find a rom that someone already patched. All this might sound complicated, but trust me it’s not. I barely know anything about computers and this kinda thing, but I figured this stuff out.

I usually get my patches from Romhacking.net, and they specify which ROM you'll need in the the ROM / ISO Information section in each page. For patching, I use Floating IPS. You just need the .ips patch and a copy of the right ROM. You could also use online patchers, like the one over at www.marcrobledo.com.

I then loaded the ISO.file with the latest patch 2.0.31 https://ffhacktics.com/smf/index.php?topic=12767.0 with the help of the following website https://www.marcrobledo.com/RomPatcher.js/

You need to patch it first with a clean emerald rom (Emerald.gba (Trashman)) . Using https://www.marcrobledo.com/RomPatcher.js/

No, ICV doesn't change shiny rate. I don't know if your game is safe with all of this, but I can definitely tell you that there is already a patch that incorporates RP, FP and ICV. You can get it from here - https://github.com/TheGag96/individual-color-variation/releases - after that you can slap the shiny rate increase patch on it, start a new game, and well, pray that everything works. It should work, but NDS patching is finicky and with that many patches risk increases.

Yes this exists for Platinum here

the xdelta patch is available to download from here. are you having trouble applying this patch? if so, we can help if you're more specific about the issue.

What you'd be changing is a constant in the file tableprinter.d over in the Gen 4 version of the mod. If you're doing this for a Gen 4 game, change MAX to whatever number you want, then follow the build instructions (which involves installing a D compiler). You can shortcut things by just replacing the table in an already-patched ROM, if you do some fiddling.
