New rubber feet for the competition pro joystick

I just put new rubber feet onto my Competition Pro Joystick.

Just in case you might be interested: the outer diameter is 12mm, the thickness is 2mm on those self adhesive rubber feet.

They are available everywhere, so just pay attention to buy the correct dimensions.

On Melancholy Hill (but it’s on a Commodore 64!) - YouTube

This is my first ever SID composition so go easy on me! The C64 only has 3 voices which made it quite a challenge!

Alternative palettes on the c64 ultimate.

The c64u allows alternative palettes, unfortunately you can’t control them programmatically from within the UCI , but you can externally through the REST API. Here I’m automatically cycling through a bunch of themes, changing it every second just to demonstrate. With readyOS (and even as a general
Tool) I’m going to make a companion app that can run any computer on your local network that you will be able to do a network call from the c64U itself so can do a call
Back to the REST API to things that the UCI can’t. Anyway here is a bash script to upload and set a palette. https://github.com/ReadyOS-C64/ReadyOs/blob/main/apply\_readyos\_palette.sh

Are old power supplies worth keeping?

I am a bit of a hoarder and hate throwing things out but these ones can fry an old computer and I have modern equivalents.

It feels sacrilegious to throw them out though…

I decided to gather all my games together and make a video of them all. I think the music fits well! How many titles do you recognize?

28 years ago I packed all my computers, books, mags and software into a storage unit when I went on a 6 month vacation to Canada... 28 years later I'm still here. Last year I finally managed to ship everything to Canada from the UK.

Yes, there are some non-Commodore titles in there... MSX, Sharp, Atari, Speccy, Dragon, TI99, and Beeb. But the vast majority are for the C64, C16, and Amiga..plus one token VIC 20 title!

The C64 games are nearly all ones I bought back in the 80's, The C16 games all came with a C16 I bought from a mate when he was upgrading to a proper computer (a C64!) Some of the Amiga titles are ones I worked on in my early days as an artist.

Sadly I'm missing all my Speccy games except Scrabble ( I was a Spectrum owner before jumping onto the good ship Commodore )

Sprite Editor in C64 Dev Machine

https://preview.redd.it/kvz24dw6712h1.jpg?width=1920&format=pjpg&auto=webp&s=c7efe34c4526fe39a8b23e38ff81b092f8920e54

I wanted to expand on a sprite tool I made around 5 years ago called Spred64 and so it made sense to integrate it into C64 Dev Machine. I created a video of me making this sprite and can provide a link to that in a reply perhaps. These guys would be made up of 4 sprites each, sort of squashed but cute versions of their bigger brothers... Nothing committed here, just all for fun and to demo the sprite tool. C64 Dev Machine has a LITE version on itch that you can start using now.

ORION C64 GAME TAPE

Hi everyone,

​I've recently dug out my old C64 along with all its software, not just games.

I was looking up some price evaluations and stumbled upon a rather strange dilemma.

​I have a copy of Orion by Rack-It/Hewson Consultants Ltd. (1988), but the front cover is different from all the ones I've found online (see attached images). As you can see, it doesn't feature the RACK-IT logo.

​Additionally, the inlay has 3 pages instead of 4, and the instructions are in Italian.

I assure you it's completely original, not a reproduction. The cassette itself is also original, but it does actually bear the RACK-IT branding.

​Can anyone help me identify exactly which version this is? Maybe a rare Italian release?

ReadyOS for all c64s with a REU

I recently built a new OS for the c64 released with about 16 apps including a new shell language with pipes and an object pipeline called ReadyShell. It works with any C64 with a 2MB REU including vice + the c64 mini etc. there is also a .CRT cartridge version to speed up the time it takes to load all the apps to REU. Once apps are in the REU you can instantly swap between them. https://github.com/ReadyOS-C64/ReadyOs/releases/tag/v0.2.3

My Commodore C64 Emulator

I have just completed my C64 Emulator. I know there are many like it but this one is mine :)

My Commodore 64 emulator is written in C# (.Net 8.0) using SDL2, ImGui & OpenGL for display/input/audio. Key features include:

  • Cycle-driven CPU/VIC/CIA integration
  • VIC raster stepping with bus-steal/stall accounting
  • SID synthesis with MODE/VOL semantics
  • CIA timer/ICR/TOD handling, serial shift behaviour, and NMI/IRQ paths
  • Keyboard and SDL-compatible game controller joystick input
  • IEC + virtual 1541 D64 file loading support, including selected command/status and direct block-access operations
  • TAP cassette pulse playback with motor/sense/read behaviour
  • Host PRG/T64/TAP/D64 loading and PRG saving, including ImGui window for bundled software

It is a cycle-accurate MOS 6510 CPU emulator with a full instruction set including all documented and undocumented opcodes.

I did most of the heavy lifting myself but in the spirit of open honesty I also used AI when confronted with some display & sound timing issues. I also used AI to do most of the UI polishing since I was keen to get it closed out... it's been a long journey.

New Ultimate or Mega 65?? I'd like to know your thoughts. Thanks 😊

As the title suggests, I'm looking to buy one or the other. Which one should I buy?

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

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.

Question Regarding Artworx's Strip Poker

I'm a writer working with the new Comupute's! Gazette magazine.

I'm writing a new piece and my question is: Does anyone out there have any information (that isn't readily available on the internet) on Artworx's 1982 Strip Poker? Specifically, on the original models, Melissa and Suzi?
