Hello, I am looking for a powermac g3 blue & white ROM for an emulator I am working on. Can someone send me a ROM? Any help will be appreciated thank you!

I don't think ROMs are allowed to be distributed here. From every emulator README that I've actually read, ROM images are illegal unless you own the exact device the ROM was made from. Like if I wanted a ROM of Nintendo Tetris for NES, I'd have to own the physical cartridge in order for it to be legal.

For QEMU G3 there is a quick written firmware replacement called openhackware,
dont have it anymore, but I have a real G3

I assume you mean the Blue&White G3 rom.
Well, the rom file is called "Mac OS ROM" and it's part of Mac OS 8.5-9.2.2.
It's in the System Folder.

This is what the difference between "Old-World" and "New-World" Macs is about. Old-World had actual ROM chips inside, but as Macs and the OS became more sophisticated, it was getting harder to fit everything on there. Old-World Macs are the ones that are usually beige or platinum in color (off-white) and have letters and numbers for names, ie: SE, IIfx, Quadra 950, 7200, 8500... up until the final ones, the beige G3s and PowerBook Wallstreet.

New-World Macs were based around the technology of "ROM in RAM", which did away with ROM chips. Instead the ROM is a file in the System Folder which contains information about the machine. When the Mac boots, the ROM is read into RAM. New-World started with the PowerBook Lombard G3 and all of the post-beige, candy-colored Jobs machines from the bondi blue iMac, blue&white G3 tower, graphite G4s, titanium and aluminum PowerBooks, etc.

This is also why for instance some later G4s have trouble running OS 9 or other older PPC operating systems - they might work, but need a special ROM file to function. Like the Mirrored-Drive-Door G4 and eMac, they won't boot from a regular OS 9 image because they are not included in the ROM file. Instead there are special discs for these machines which include the special ROMs they need.

if you need a B&W G3 rom get a hold of the Disc that they ship with from the factory. there should be a file called "Mac OS ROM"
