[Help needed] How do I create an injector using an existing one?

[RRG_J0K3Y]

I have no idea if this is the correct thread to post this, if it is not, could someone tell me where and I will move it.

I want to inject a file into my game using an injector. However I am sure the injector is detected and was suggested that I create my own using the old injector by just changing a few things.

Is this a simple process/Where can I learn to do so?
Or does anyone have their own injector that they created, that they wouldnt mind sharing?

Thanks

Option 1, and the most likely:

Assuming you have the source code, extend it with whatever changes you have on your mind.

Option 2:

If you don't have the source code, you could try to use a decompiler to obtain the source, and then extend it.

If you are asking how to make an undetected injector, then I don't think you will find an answer here.
