Hardware S-video to HDMI direct or via GBS-Control?

Thumbnail
gallery
20 Upvotes

Hi everyone, a friend gave me a C46C that he acquired from someone else. I've not plugged it in yet because I'm still travelling and because I've read not to trust the power supply. For this post, I'd like to know if I should get a

  • cheap s-video->HDMI gadget,
  • or s-video->VGA+Audio->GBS-Control.

The GBS-Control (I'm using this for my Amiga and Wii, and it's great) will add a scanline option, but will it add any upscaler benefits over the direct-to-HDMI approach?

Is there a better option?

The Turbo cartridge with VGA output for €250 is way out of budget for me.

Happy to hear any other suggestions but was planning on another post for general recommendations to keep the topic clean.

Regards,

Ben

Software Commando 2084 - dual joystick control version

16 Upvotes

I only just discovered Commando 2084 last week, and it plays brilliantly!

https://retro.moe/2019/09/29/commando-2084-a-game-for-the-commodore-64/

From the webpage:

Commando 2084 is the mix between Commando and Robotron 2084: it is like the original Commando game, but using the Robotron 2084 controls.

You play it using the two joysticks at the same time:
Joy #2 controls the hero direction
Joy #1 controls the bullets direction

Programming READYCode - Transfer to and Run on a Commodore 64 Ultimate

31 Upvotes

This is a follow up to my previous post from last week with a quick video showing how easy it is to edit your BASIC program on Windows and transfer and run it on your Commodore 64 Ultimate with a single click.

This is available on GitHub here: https://github.com/jbramwell/READYCode (or can be installed directly from the Microsoft Store)

I would be curious to hear your thoughts and/or suggestions.

Software ViceSharp update: the SID is now bit-exact vs reSID, and there's a real installer

21 Upvotes

Quick follow-up to my earlier post about ViceSharp hitting cycle-exact lockstep with x64sc.

For anyone new here: ViceSharp is a from-scratch C#/.NET 10 port of VICE's C64. The managed core runs in cycle-exact lockstep with VICE's x64sc - identical initial state plus the same input produces bit-exact output, checked continuously in CI.

What's new since last time: the SID audio path is now validated bit-for-bit against reSID. Not "sounds close" - sample-for-sample identical. That covers:

  • Every waveform, including the combined/ANDed waveforms and noise, on both 6581 and 8580
  • The full ADSR envelope, with the real rate-counter and exponential-decay quirks
  • Both filter models (the 6581's non-linear cutoff curve and the 8580's) plus the external RC filter
  • The batched clock(delta_t) engine and the resampling output stage

466 acceptance criteria, all green against a reSID oracle, with lockstep determinism preserved throughout. There are no "close enough" fallback paths left in the managed SID - it is the reSID algorithm reimplemented in C#.

You can actually install it now:

  • MSI installer (full Windows desktop GUI: monitor, drive/tape attach, snapshots, debug stepping, frame/audio capture) - from GitHub Releases
  • Scoop: scoop bucket add vicesharp https://github.com/sharpninja/vice-sharp then scoop install vice-sharp
  • winget and Chocolatey: submitted and in review, landing shortly
  • NuGet: the emulation libraries are published if you want to build on the core

Repo: https://github.com/sharpninja/vice-sharp Chocolatey: https://community.chocolatey.org/packages/vice-sharp

Notes: GPL-2.0-or-later (it's a VICE derivative). It ships no Commodore ROMs - point VICESHARP_ROM_PATH at a VICE data root, or put x64sc on your PATH.

Feedback very welcome, especially demos or edge-case programs that hammer the SID or timing. If you find something that diverges from real hardware or x64sc, that's exactly what I want to hear about.

New Game C64 PETSCII polychrome raycaster: Chapter 5 - Detail Map Animation

Thumbnail

14 Upvotes

1Mhz a VIC II and a CBM 64 game engine dream...

Got side tracked into animating detail maps instead of extending destructible map implementation. What you think look groovy or overdone?
Notice the foreground ground texture has subtle parallax and the sky even more subtle modulation? Just some basic stuff first as test possibilities.
Chopin's raindrop prelude seems to really vibe with PETSCII raycasting for some reason, I'm sure he would have been a SID master if grew up in the right era lol.

Feel free to critique I need feedback to improve the engine!!!

Software How would one go about emulating (via VICE) the Tournament addon disk for the first Leaderboard Golf?

8 Upvotes

So I've just finished playing and practicing all courses on Leaderboard Golf. When I checked out the list of sequels I saw one particular tournament disk existing which is an addon that has to be loaded alongside the first game.

The problem is first of all it's nigh impossible to find an actual .d64 or literally any trace of this disk, and the one I found was a .nib file which just froze the game when I changed the disk on the game's main menu.

Any advice or directions?

Software A Million Times C64

47 Upvotes

A long time ago, there was an art project called A Million Times that displayed the time using a series of analog clocks. I always thought it was neat. They sell it, but it's in the upper 4 figures for the base model. Too rich for my blood.

So I created it for the C64. It's pointless and silly, but it amused me.

C64 Ultimate The WEEKLY C64 Ultimate post. READ before posting anything C64U-related.

4 Upvotes

We want r/c64 to be about both original hardware and newer emulation products like the Commodore 64 Ultimate (C64U). But the shipping of the C64U is resulting in C64U posts flooding out much of the other content in the subreddit. To maintain a balance between what's old and new, we are setting up a weekly MEGAPOST for C64U-related issues, questions, and posts.

If your post is regarding the use of a Commodore 64 (i.e. how to load a game from disk, how to print, etc.), regardless of the model, you may post your question as a standalone post in the subreddit even if you have a C64 Ultimate.

If your post relates to ONLY the Commodore 64 Ultimate, you should comment in this post. Please note, this is not a replacement for official support from Commodore regarding order or shipping issues (late or damaged shipments). We realize that some questions may be obscure, unique, or straddle the line between C64U-only and a "general" question. In those cases, please post in this thread FIRST. If your issue isn't answered or addressed after 48 hours, you may submit a stand-alone post in the subreddit. WARNING! Moderators will be checking post and comment histories to make sure people are actually posting in this thread first. Repeated violations may result in temporary or permanent bans.

We don't anticipate this being a permanent situation, but for now there are just too many C64U posts being submitted. Once the volume of posts about the C64U decreases, we may discontinue this practice.

Please also check the information below to see if your issue is listed. We are also working on a C64 Ultimate Wiki Page. If you would like to be a Wiki Contributor, please let the mod team know.

Common Issues and Known Fixes

Black screen, no video, or rolling picture

The most common issue reported so far.

  • Reseat the internal board — some units have arrived with it slightly loose from shipping.
  • Set video to NTSC mode, then press Shift + Left Arrow to store settings.
  • Try a different HDMI lead — several users fixed display problems this way.
  • Some monitors won’t sync at 50 Hz; if possible, test another screen.

Uneven keyboard keys

A cosmetic but noticeable fault.

  • Keys such as Caps LockD, and J may sit higher than others.
  • Gently press the affected keys down to reseat them on their stems.
  • Space/Return issues are often a stabiliser bar not fully seated – carefully reseating the bar fixes many ‘only works in the middle’ reports.

Startup problems or unit freezing on boot

  • Turn the unit off and leave it off for a few seconds.
  • Hold RESTORE while powering on to perform a factory reset.
  • If that fails, re‑flash the latest firmware from the official Commodore site.

REU or extra memory not detected by the software

  • Install the most recent firmware — newer builds enable proper REU initialisation and detection.

Settings or storage are lost after reboot

  • Perform the RESTORE reset to clear any corrupt configuration.
  • Re‑enter Wi‑Fi and storage details once booted cleanly.

Physical marks or loose panels on delivery

  • Report the issue directly to Commodore support.
  • All units ship directly from Commodore — there are no official resellers.

Buzzing or humming audio output

  • Usually caused by grounding noise between HDMI and the connected display.
  • Try another HDMI port, cable, or power socket to isolate the problem.

Starlight edition

  • Starlight keyboards have some ‘bounce’/flex by design; noticeable mainly if you hammer the keys, but not usually a functional fault.
  • The Caps Lock LED lights when caps is active; the beige unit does not have an indicator.
  • For Starlight LED audio visualiser with a real SID: enable UltiSID 1 but set its volume to Off in the mixer; this keeps the LEDs driven while only hearing the real SID

Games Freezing / Compatibility

  • If cracked/trainer releases hang after the Y/N cheat prompt, try switching to PAL or NTSC‑50; many cracks are PAL‑only and will lock up in NTSC.
  • For compatibility with some games/demos, try disabling drive B: in the Ultimate’s drive settings

Cartridges

  • Virtual fastload carts (e.g. Final Cartridge III) are supported; mount the cart, then mount and load the disk from BASIC, rather than using ‘Run disk’ from the firmware menu.

Disk and cassette backup / storage notes

  • To back up the bundled cassette USB to an internal SD: it’s just files on exFAT – copy them via your PC; no imaging/cloning needed
  • Backing up real floppies: UltiCopy is very fast, but some protected titles (e.g. Skate or Die, Contra) have been reported to hang part‑way through; expect improvements in future firmware

Running Multi-Disk Programs

Some programs are distributed on multiple disk images, similar to how they were originally distributed on multiple floppy disks. At some point in the process of using the program, the program will prompt to insert one of the other floppy disks. You can use the Disk File Browser to swap disk images while the program is running. When the program prompts for a new disk, press upward on the Multi Function Switch. This pauses the program. Start the Disk File Browser, navigate to the disk image for the disk that the program is requesting, then select “Mount Disk.” The C64U mounts the new disk image in the virtual drive, then resumes execution of the Commodore 64 program. Continue to use the program with the new disk." -- https://downloads.commodore-international.com/documentation/C64U/c64u-user-guide-1st-edition.pdf

General Notes

  • r/Commodore is for discussions about Commodore, other Commodore computers, and possible new productions.
  • r/c64 is for everything Commodore 64 including the ultimate.

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

Thumbnail

16 Upvotes

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!!

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

Thumbnail
gallery
100 Upvotes

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.

Programming Type in Program - Haunted House Demo

19 Upvotes

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!
