We would go to Walden Books in the 80's and steal the passwords out of the Compuserve books on the shelf. Good times

"Low Lights" C64 OPL Version!! | FM Synthesis on the Commodore 64 with SFX Sound Expander!

Hey guys! If you are already a subscriber to my YT channel you may have checked out my recent (and officialy first) OPL2 chiptune "Low Lights" that I released some weeks ago. Since then Daniel Illgen (Insane), a great coder from the C64 demogroup Rabenauge reached out to me with the will to make a C64 conversion of the track using the 9 channel polyphony of the SFX Sound Expander. By that time I wasn't even sure this was possible. Since I am SID musician when it comes to C64 music I must have missed out on the OPL possibilities that this FM cartridge offers. The result really blew my mind! Enjoy!!

Assembly or Assembler?

A lot of C64 redditors probably know that C64 games, generally speaking, are written in a low level language using software tools known as assemblers. There does, however, seem to be conflicting ideas on what the name of the programming language itself is.

Do you call the language "Assembly" or "Assembler"?

Type in Program - Haunted House Demo

Since I was a child I had the book

"Write your own Program: Advanced Graphics: Haunted House"

(On Archive.org - https://archive.org/details/Write_Your_Own_Program_Advanced_Graphics_Haunted_House/page/n45/mode/2up )

but I never managed to type the whole thing in.

This far out I would have assumed someone, somewhere, would have uploaded a D64 of the final program. I've even toyed with a few apps/websites to OCR the text and auto-type it into Commodore Basic, with just enough errors in characters and syntax to make it not work. Not to mention, it's very hard to find the equivalent PETSCII characters on a modern keyboard and emulator. I guess, despite there being monochrome pictures in the book, I always wondered how the final actually looked/sounded. Was anyone more tenacious than I? Or does anyone know of a disk rip? I didn't find it on the CSDB.

My ten year old self, endlessly flipping through the pages in the early 90s thanks you in advance!

READYCode - A BASIC editor (IDE) for the Commodore 64 Ultimate (and VICE)

I built a modern(ish) BASIC editor for use with the Commodore 64 Ultimate, which I also modified it to work with VICE as well because, well, why not?

Long story short, when I got my C64U a few months ago, I was excited to start coding in BASIC again but I quickly found that I missed the modern code editing features we have grown accustomed to (e.g., cut/copy/paste, syntax highlighting, code completion, code formatting, etc.). So I built something that integrates with the C64U's REST API (as well as the VICE emulator's API).

I'll leave it to you to determine if it's anything that would be beneficial for your day-to-day BASIC programming but, in my case, I simply wanted a better code editing experience that is also integrated with the C64U.

There are likely other editors like this out there (for the C64U), I didn't really look TBH. When the idea came to me I was excited to build it out so I could then use it myself.

The source code is available here on GitHub: ttps://github.com/jbramwell/readycode

You can also install it from the Microsoft Store here: https://apps.microsoft.com/detail/9N70DV3X3C6S?hl=en-us&gl=US&ocid=pdpshare

You can also read more about it here: https://bitsandbytes.life/2026/06/readycode-an-impulsive-project

I am working on a video now and should have that up on YouTube within the next few days.

It's still a work in progress with more features to add and likely some kinks to work out. I would be curious to get your thoughts.

How Rob Hubbard’s C64 music player worked

Luxocrates is back after 5 months with another video. I don't understand a lot of what's being discussed in these videos but I've been enjoying this series a bunch nonetheless.

Recommendations?

I’ve just got my first c64, these are the games that came with it any decent ones I should try out first? It predates me by about 15 years so I’ve not heard of too many,

Thanks!

Sometimes in life, you just need some small but beautiful platformer like Nixy. C64 is a goldmine for platformers.

Takes you into some other world. Some would say that I am escaping reality. But nobody knows what reality is.

Sony removes physical media from the PlayStation, and the old wise C64 responds in time by teaching it a lesson.

There’s no need to repeat in detail what’s happening in the PlayStation world right now, the wave of protest over the decision to phase out physical games starting in 2028.

But like an old yet timeless and wise warrior, our C64 immediately managed to teach Sony a lesson in… life, I’d say, and I believe this will also bring you some beautiful, old-fashioned, yet vibrant vibes.

Many of you knows Impossible Mission 3, the new chapter of the game released few weeks ago for the C64. When yesterday I decided to buy a physical copy of the game, I was surprised positively.

I found that the website is temporarily suspended for purchases for a good reason. Psytronik has received so many requests for physical copies of the game that it had to suspend sales for a few weeks, but everything will be back to normal soon, as stated in the announcement in the site:

https://psytronik.bigcartel.com/product/impossible-mission-3-c64-usb-tape-limited-edition

I have to wait for my physical copy, but I'm happy.

And Sony, you have a lot to learn from this timeless, wise old warrior, the C64!

New Commodore 64 and 1701 setup trying to get the C64 working and refurbished

Hey everyone, I am new to commodore 64 so be patient I will do my best to explain all the important info.

I recently got a 1701 that required repair, I did a full recap and it is working beautifully. I also picked up an in box commodore 64 which seems to be in great cosmetic condition and very clean. I waited a month for a luma chroma cable to arrive (first one got lost in the mail). Upon plugging it in I discovered the commodore doesn’t display video.

Here are the troubleshooting steps I have taken.

AC Adapter voltage output was measured prior to use (measured and left on for an 1hr and measured again). The red LED light does come on as it should.

I connected an RF cable and hooked up to another tv and still no image.

Note: there is no flicker or audio signal that anything is attempting to get into the tv when switching on or off either RF or through luma chroma.

continuity tested the fuse and visually inspected and fuse is good

I measured the voltage of the CPU, PLA, and RAM and all measured 5.15v

I measured CPU PIN 1 (RESET) 0.02V
CIA PIN 32 (RESET) 0.04V
reset line resistance to ground 0L

NE556 Pin 4 5.15V
NE556 Pin 1 0V (When powered on)

the board is clean visually and no signs of leaking caps

when powered on for a minute I ran my finger across all chips, no hot or warm chips felt

I am looking for advice before I replace the NE556 chip. Is there a supplier I should go to for the chip? Is there any other work or parts I should do or replace while I am repairing this console that are prone to failure?

I figure this is some sort of reset hold preventing the console from starting.

appreciate any insight from the community

What does this mean?

This is on one of the floppy disks I got in a lot. The disk has three programs on it and when you boot up any of them it says the game title and “broken by” then something like it says in the picture above. Any information is helpful. Thank you.

Head Over Heels Extended

A brand new version of HoH has just been released. Essentially recoded from the ground up with speed up even on stock C64. Extra speed boost on C128 and C64U. Level designs taken from Speccy version which had to be simplified to run on C64 at all.

Get it on CSDB.

Samurai Warrior! What a game. Spent so many hours on it.

Anyone else love this game? Mine still has the Boots (UK pharmacy chain) price tag from all those years ago! Firebird games were generally pretty good.

Second thing I did with my new c64u

First thing I did was crack the case to see what was rattling around in there. It was an extra screw. My first computer was a c64 in 1984. I used it to log on remotely to the school mainframe (someone wrote an 80-column terminal emulator back then) and also to play games. I wanted to write games too, but not in basic or assembler. So I wrote a Pascal compiler by adapting one out of a book. I spent the rest of my spare time working on that compiler and never got around to writing games. I work in compilers to this day.

Does anyone remember quantum link?

I miss the good old days of chat rooms and q-link. Today's internet has nothing on them. I used to be CaPlayboy back in the 80's. Anybody want to comment or reminiscent feel free to comment. Bonus points if you remember me. 😁

Probably a lost cause but...

A million miles ago... I wrote a BBS program for the c64. I have the floppy disk and can read them. But I am blocked when I try to list the program. I don't remember how I blocked the list command. I have tried poke 775, 167 to unblock with no success. However I did it, when the list command is entered, the computer only responds with the word "Advent" Which was the name of my program.

Anyone have any clues of how I may have done this? And if there is a method to undo it?

TIA

ISO Lester C64 physical cartridge

I am looking for a physical copy of Lester by Knifegrinder. I'd prefer the limited edition interactive plexiglass cartridge but I'd settle for the standard edition. This would be a gift for my dad.
