For anyone running into the issue of compiling 'wrapper.s' instead of the example file, I could solve it by changing cl65config.json, adding "input" and changing "params" like this: "input": "wrapper.s", "params": "--verbose --target nes examples\\01_XandY.s" I'm guessing that this has something to do with dependencies and the order in which the files are compiled, and there might be a better way to configure it, but it worked for me.

Wanted to thank you. I am working on a new Zelda 2 Randomizer that uses a different approach to the randomization and I used your videos to help me figure out why certain maps in the game don't respect the level exit data, and I was able to follow a trace and find the code. Using your videos and some 6502 ASM wikis I managed to figure it out. For some reasons maps with a map number greater than 29, ignore the level exits and default to all "go outside" exits. Thanks for the help =).

The 6502 was an amazing CPU in its day, and remains one of the best choices for microcontroller foundations 50 years later. It's architecture and assembly language offer a straightforward path to creating sophisticated apps without high-level languages/compilers. It has a few things that have to be digested, like the difference between indirect-indexed and indexed-indirect modes (also known as indirect-x and indirect-y), but the ability to use either as the situation demands is super power, and permits C-like pointers and pointers to pointers to be easily created in assembly. It's a time-tested chip with utility that extends far beyond the typical useful life of such a complex-purpose unit.

I agree wholeheartedly. I think 6502 is my favorite assembly language to work in because it is incredibly expressive given such a concise instruction set. While working in on comparable architectures like Z80 I really miss the indexed addressing modes 😭

@squirlmyАй бұрын
I'm just a student now, but I'm remembering the Atari 2600. Unlike many here, I'm older than the 6502 chip! and knew people who started on the original C64, for example, who went on to code higher languages on Windows, so I know the answer to your question. Of course the principles of programming are the same, if this is your first low level language, it will help you to learn others. OTOH, it's also like asking if you can build a dam after learning to build a swimming pool. The point of C specifically, and the C family generally, is to hide what is going on at lower levels, to do things in one line that takes several lines of assembly. Here's another metaphor -it's like wanting to grow an orchard after learning to grow algae cultures in petri dishes. It's much better to get an NES emulator in Windows for those games. You can use the latest VS Code or Codium editors in Windows to write 6502 code, and test it on an emulator. and the final product should run on the real hardware. But to make a Windows game? That like making a winter wardrobe out of summer clothes sewn together. It's not impossible, but you are going to see it's a lot of hard work for no reason.

Other than that it might be an issue with not having permission to access the file… though that seems unlikely. Unfortunately I cannot think of another reason why this might be happening :(

@oscarw.alcantara44592 жыл бұрын
Don’t know if this will help, but try it. 1st. Make sure you have a working assembling process (on his video NES Development) 2nd. You have to change the “input” and “params” lines on the cl65config.json code to indicate what’s the target and end result. For example: If you create a .s file named “example.s”, then your cl65config.json has to read (if you have the exact default setup that he explains in the NES development video) this: { ”executable”: “C:\\cc65\\bin\\cl65”, “input”: “example.s”, “params”: “-verbose -target nes -o example.nes” } Note how you have to change the input (which code are you targeting) and params (to what do you want to change that code).

Hello, great video ! I wanted to start learning and creating games for NES for a while (more than 1 year) and you made me start, so thanks for being able to break my lazyness xD ! Could you share the code that helps to prevent the grey screen on FCEUX ? I visited some websites but don't really understand if it's due to the emulator, an error in the code or just basic NES functionning. Also, do you plan on creating a video about the base code of a NES game (explaining VECTORS/HEADER segments, how to display a simple sprite on the screen, etc...) ? I really think it would be helpful, especially from you ! I hope you're having a great day !

Why my code in debugger start in index $8070?

At 7:00 you start with an assembler without explaining it is an assembler. Try to explain MC with a simple MC editor only before jumping into assembler editors.

I assume this could be used for making Atari games.

how could we make games for the snes because the processor core is still 6502
@NesHacker2 жыл бұрын
I’m hoping to branch out and do some snes stuff too in the future. Focusing on the nes for now until I get more of the bases covered for the system :)

Was good at 6502 back in the 80’s. Very nice limited size instruction set compared to todays CPUs

Haha, I wasn't... but you're not joking. Even modern micro controllers make the 6502 look like it was invented shortly after the wheel 😆

@@NesHacker your videos are very interesting. I learned by reverse engineering code on the Atari 800 using Omnimon which was a real-time editor/debugger that you could jump into anytime with a two key sequence. Learned a whole lot that way… those were the fun days of computers… your videos bring back a lot of memories for me. Thanks and nice job.

I don't know what is happening but whenever I want to make my own workspace and follow your command it never works! But your code is perfectly working without any fault. Even I copied all of your code into a new workspace and it's not working

Assembly language is difficult for many people. Why not make lessons for the C language?
@NesHacker9 ай бұрын
Because most games were made in assembly back in the day, it gives you more control, it's very useful to know when debugging, essential for ROM hacking, and most important of all: because I like assembly ;)

if want learn 6502 assemply. then not focus NES. just assembly forget system specific this is is this address. just assembly moving bytes. even better build own computer and sure it has no video card so basic moving bytes is all you need learn. next step is use that to control devices
