Gameboy Memory Filling up for some reason

Hey! I wrote a quick program in hex. In my emulator, I check all the ram and its filled with random numbers which I never placed there.

Do I have to clear this manually? Ive checked all my head info and it works just fine.

Hey, shiblivs, welcome to Gameboy development smile

Yes, at startup not all RAM is cleared, so any RAM you use you will have to clear/initialize first.
If you initialize every variable before using it and your program works, that's great big_smile
