*UPDATES* - There is a problem with spaces in paths when using VSCode to build the project. If you run into issues, try moving the project folder from the Desktop to the C:\ (or any other path that doesn't contain spaces) [Thanks ​ @Plazma Dolphin & @keithstone001] - Mesen is a very nice alternative emulator to FCEUX for game programming, check it out: www.mesen.ca/ [Thanks ​ @Nesrocks Gaming Videos ]

[@GustavoValdiviesso]

Yes I much prefer mesen (not that the others you mentioned are bad in any way).

[@sirgouki6207]

Good computer users NEVER user the desktop to save files, especially due to all the clutter it causes. If you're a programmer, beginning or other wise, you need to learn proper folder structuring ASAP. That includes not using spaces in folder names, regardless of whether or not the OS allows it simply due to not all compilers recognizing it. And as a programmer, you never know when you're going to try something different.

[@elguardallavesdejaal]

¡Thankyou, I was having the space problem!

[@inceptional]

@@sirgouki6207 So, the main tips are to never use the desktop to save files (What, just because it causes clutter?) and don't use spaces in folder names (which I assume is true of filenames too)?

[@kyleolson8977]

​@@inceptional It's not just that it's clutter on the desktop, it's that if you use the desktop this way you're mixing all kinds of clutter. The desktop is a soup of app links and other items on install, random temp files from things, it's very easy to accidentally mess with. By default you'll also copy the files over to every windows computer you log into with your personal account. Projects have huge numbers of files and backing all those tiny files over to every desktop is bad. The desktop was designed for light items, like shortcuts. The desktop should be disposable because that's how the OS treats it (Except for deleting a single shortcut. One PM thought that was really important to make a big deal about many years ago. Lots of things at Microsoft could be traced to one random PM or another. For example, I think I know who was responsible for complaining when you try to switch browsers). Many tools don't like files on the desktop for reasons, though it's not very common to not be able to handle it. You honestly don't want to use either Documents or Desktop for source code if you can avoid it because backing up to OneDrive is messy for source code even when you're one person. Using the VS20XX default option of C:\users\\source epos and backing up to github is far better and not very hard anymore. As for the spaces ... you shouldn't have to care. That attitude is fairly old. I'm not saying it doesn't happen, but it's rare enough nowadays that you shouldn't look at it as critical. If you hit it, you can usually solve it by either using quotes or the 8.3 file name (look it up). For "reasons" it shouldn't come up in modern software unless a toolmaker makes a mistake. Because tools are so likely to fail if they can't handle spaces nowadays it's almost certainly on an old tool or a tool used by a very limited set of people one way or another. I do not always follow the spaces rule nowadays. I am more likely to because I am old and crusty, but if the spaces naming is better I will avoid it. Additionally, if spaces is a thing that's supposed to work and if you avoid using spaces you're potentially creating software that's part of the problem. There's a time when we need to move past attitudes and except the small risk of bad old stuff. If you're aware, you can usually fix it early. I have only hit it once in the past half decade in a way that can't be fixed with quotes or 8.3 because the person who wrote it wasn't around the company anymore. I fixed the code. World moved on. Sometimes you might not be able to do this and you might have to rename your folders. I've also done this a few times in the past couple decades. More often a long time ago. Rarely a big deal when you hit it. The spaces in folders issue is not like the desktop. Saving projects on the desktop is bad all around. Spaces is low risk and something you should spend little time worrying about but be aware of. We're talking about 6502 stuff in this video, but modern programming shouldn't worry about 1980's problems.

[@Bunnokazooie]

I never would have thought to explain what syntax highlighting is in a programming video, it is really awesome how you are able to get in the mind of a newbie.

[@NesHacker]

When I first started programming most editors didn’t have syntax highlighting. So I remember vividly the first time I used an editor that did (Visual Basic 3.0 in windows 3.11) and how game changing it was.

[@Akutabai5]

I've been getting more and curious about trying to make a game for an older system. I'm glad I found this channel, you break this stuff down very well

[@ohno5559]

I love how you explained what was happening at every step. I'm a total beginner and using Linux instead of Windows and it still all worked. I knew what I had to change because you took the time to go more in-depth than just listing off the steps.

[@zukinokaemono]

I followed the described steps, but on macOS, and was able to build a demo ROM! I've installed cc65 with brew and set /usr/local/bin/cl65 as "executable" for cl65. Thank you for clear instructions, it was a breeze. I'll give a try to more of your tutorials :)

[@sir_no_name1478]

I have to say that you are really good at making tutorials. I mean idk for which target group was that video? I thought for beginners because you make the steps so simple and clear. But also as an advanced programmer my self I learned something and did not get bored over topics I already know about. I really admire your teaching skills sir ^^.

[@NesHacker]

Mm yeah I get this a lot. I didn't have a target audience for the video. I kinda just thought "What are the essential things you need to begin programming," narrowed down that list, and tried my best to be thorough explaining each part. In retrospect I could have probably cut a lot of the "Click this link, press this button" stuff and just showed it as I explained broader topics.

[@sir_no_name1478]

@@NesHacker pls do not get me wrong. I use Jetbrain products most of the time and vs code sparingly. I use it more for really small stuff where notepad ++ or gedit do not cut it. Therefore I am by no means an expert in this ide. And I have learned a lot. I think your skill in explaining is highly underrated. Sadly I have Linear Algebra Examen in like 6 days and can not start NES hacking ^^

[@kbaeve]

Gotta give some props for making a video sooooo detailed, that even grandma can sit down and.... code assembly.

This is very exciting, I've made a good living programming but have never written a game, it's all been business applications.

First, I just want to say, thanks for a great tutorial. As a veteran web developer, I was able to get the demo up an running in less than a half hour. I thought the tutorial video was very helpful. It was a little verbose at times, but it is perfect for beginners. My only criticism would be the personal commentary regarding SourceForge. If it was intended to break up the monotony of dry coding dialog, then don't worry about that. I'd imagine most people coming to this type of video are just looking for the raw information we need to get started. Everyone is aware that some sites are dated, filled with advertisements, and include annoying time delays. Highlighting it in your great content only serves to promote it.

Heck yeah! I think sometimes folks get bent out of shape over the *exact* tools folks use, but it really comes down to personal preference and what you're trying to accomplish :D I switched from FCEUX to Mesen after viewers suggested it, it can still be a bit *crashy* for me, but honestly the interface is pretty good.

[@victornpb]

I would like to provide some feedback, while I appreciate the thoroughness and almost zero assumptions approach, i found the choice of what things you chose to go and explain and not a bit odd in a few places, for example you explain what text editor is and what is syntax highlighting is, but just after you mention debugger and hex editor while recommending an emulator with no further explanation of what those things are. I hope you take this as constructive criticism, because I used to do the same thing while explaining things to people. and for me this occurred by not really understanding what my target audience was, you probably started the video wanting to target everyone but later decided that your target audience probably already has some programming knowledge. That being said your content is very good and I’m really glad youtube recommended your channel.

[@NesHacker]

Yeah it's pretty hard to get this stuff right, especially when trying to balance information, entertainment, and assumptions about the audience's level of knowledge. Some folks who are more accustomed to coding come in angry that I was too pedantic, some folks find it just right, and others don't get it at all. Couple this with the fact that it was one of my first videos and it's not surprising the result would be flawed. That said, it's the most successful video I've ever produced, so I'm kinda like... "Maybe flawed is in some ways good, too?"

Great video man, thanks! Any recommendations of sources to study from while we wait for your next awesome videos?

[@NesHacker]

I have four videos on basic 6502 assembly, but honestly the best thing you can do is to just program stuff, anything, like a lot. The NesDev wiki has a ton of information, and you can probably find the answer to most questions you’d have by using it. But it’s often a bit jumbled and some articles are stubs or poorly written, so you often have to test things and do some work on your own to work it all out. Bottom line: pick a thing (like sprite rendering or w/e) then hack on it and use the wiki until you have something working on the screen. Then pick another thing and repeat :D
