SOLVED: Updating the animation of a sprite given the refresh rate and time

Hello guys,so let's assume we have a display refresh rate of 144hz and i want to display a sprite with 9 frames in 0.25 second.Now if it was 1 second instead, it would take 16 frames to update the sprite's frame by one.In this case, it would take only 4 frames before it updates the sprite's frame by one.I also want it to also work for a display refresh rate of 60hz.So in the case of 60hz, it would take 1.66666666667 frames instead to update it.My sprite function looks like this : void Put_s...

What causes "RAM leaks"?

I am writing a simple game in ez80 assembly, and every single time I run the program, my calculator's free RAM goes down a lot .I can run the game maybe 4-5 times before it runs out and a memory error occurs.Is my program simply not deallocated from memory, if so, how do I get it to?

Double buffering makes program slow & visual artifacts for each render.

I added double buffering into my program, as before you could see it rendering visually and flickering.But now with double buffering, half of the screen flickers (not exactly half, I can't find a pattern, but it's mostly pixels at the bottom), and it now takes around half a second to render, before the buffers are swapped again.I'm assuming this is because we wait for the interrupt, but it still seems to be very long. call SJQ_setgraphicsloop: ; Simple buffer cleaning, sets everything to 0...
