I appreciate all the help this forum has given me so far, but I'm back with another problem. I currently have a menu screen where you select the next screen by using the d-pad (up, down) and the SELECT button. This menu works fine, but when it transitions to the next screen I get a strange effect we...

Just so I'm understanding. There are always 64 sprites being drawn, but some are offscreen?

Yeap, That is exactly what I did!

It works perfect now. Thank you!

I found the problem, and it had to do with indirect addressing. I was able to fix most of the graphics issues, but I still have some sprite pixels in the upper left corner of my screen that I cannot account for. It's probably something with my Sprite Buffer and OAM Copy code, but I can't pinpoint wh...

After spending a few hours making adjustments and fixes to the code, I was able to make significant progress. I still have a graphics bug that I am not able to pinpoint the root cause. I have attached the current version of the code and an image that shows the problem. Comparison.png The left image ...

Honestly, I'm thinking the problem is more me and my lack of understanding of asm6. Somewhere the code is not doing what it suppose to, even though it compiled. Going to work on it more tonight.

I'm trying to compile some code using ASM6 but it is not working and I can't seem to figure out why. In the attached code, when ASM6 hits the block LBL.GameState.Initialize: JSR LBL.Scene.Initialize.Launcher LDA VAR.GameState.Construct STA VAR.GameState RTS It converts it to the following when disas...

What exactly is a "Scene", in this context, in the first place? A Scene doesn't have an official definition, and is more of a way I can break down a game into it's smallest programmable parts. If I think about Legend of Zelda, then each square of the map could be it's own scene along with...

Here is an example of a the code for a "Scene". -------------------------------------------------------------------- SCENE 1: Sprite Animation Test -------------------------------------------------------------------- DESCRIPTION: This scene will test a sprite animation. Pressing left will ...

Work slowly continues on the development of an IDE (integrated development environment) for programming games for the NES. I finished laying out the Universal NES Game Engine and have converted it to 6502 Assembly Code below. I will be building my own compiler in the IDE, so there may be some non-tr...

Hello everyone! I have been a lurker on this site for a few years now, but finally registered today. As with most newbies here I have these lofty goals of developing my own NES games. I've read the Nerdy Nights, NESprgmn, NinTech, and Metopal tutorials ("I AM EXTRA") and feel I have an ade...
