Short answer: no.
Long answer: no, there were no "generic tools" to make games in a "magically simple way" "back then". Commercial companies made their own games from scratch, using entire teams of people, developing their own tools in the process. These were all intellectual property; nobody at that time was making generic and free tools for making NES games. Nintendo probably would have sued them anyway***.
If you want to get into making NES games -- your several forum posts within very short periods of time, i.e. less than 24 hours, are indications that you do, but
this is not very promising or open-minded -- you're going to have to learn how the console works, and get started with assembly language.
If you don't want to start with assembly language, but are more willing to learn something like C, you can try
nes-starter-kit which just got released a few days ago. However, you are still going to have to learn assembly or deal with it in some way eventually -- there is no debugger for the NES (or NES emulators) that let you correlate lines of C code to actual 6502 assembly code. So, you will need to learn some 6502 assembly either way. For help with nes-starter-kit, talk to the author directly (or on GitHub Issues) in that thread.
Please remember: you want to program games on a system made over 30 years ago... yet you don't want to learn anything from 30 years ago. You're not being very realistic. That's just my opinion though.
