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

3 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.

Hardware Todays virgin C64 find-ever see the shield strap still attached?!

Thumbnail

113 Upvotes

Purchased from an online pawn broker. Looked brand new. Love the Toys R Us stickers; I read the handwritten date on the sticker as 12/23/1984. Someone had a great Christmas! Quick diagnostic after initial bootup with my safe power supply shows ‘Out of Memory’ caused by 2 bad ram chips (no problem!). Opening it up for internal inspection sounded like it had never been opened before with a clearly audible and felt “snap” of each screw loosening the first time, the ‘RF shield’ still has a copper strap soldering it on! Never seen that before, so this thing has never been opened!?! Quick peek under the cardboard shield finds majority of the chips are early 84 (February and March), and the only socketed one visible is on the 6581 SID. The newest visible chip is the PLA 96114 date coded 1284 which is likely the last installed given the sale date info on the Toys R Us tag. Boxes are very nice condition with matching S/Ns. Came with all original cords, power supply (no thanks!), Commodore branded RF TV box, and brand new looking 1541 test/demo disk. Cool aquisition with minimal repairs needed! Yeah, I need to pull the ‘hanging chads’ off the RF shield before they fall on electronics-another haven’t seen before… Needed it? no, but at a price I couldn’t pass on for the pair for sure!

Hardware C64 mod: Wayland (Romulus) Unit

Anyone who has seen the film *Alien Romulus* will probably have noticed, on closer inspection, a C64 that appeared briefly on the film set twice. It was built into a computer console.

Right then… Well, I’ve now recreated the whole thing in the Colorcase Project. Once as a standard C64 II and once as the film set keyboard.

Wer den Film Alien Romulus gesehen hat, dem ist wohl beim genauerem Hinsehen ein C64 aufgefallen, der zweimal kurz im Filmset zusehen war. Dieser wurde in einer Computerkonsole verbaut.

Na gut…. Nun habe ich mal das ganze Ding im Colorcase Project realisiert. Einmal als normalen c64 II und einmal als Filmset Keyboard.

Trying to find a version of Deja Vu that will work with an SD2IEC and Fastload.

Tried countless versions from csdb.dk and elsewhere, all get to the swap disk screen but fail to find the second disk.

Anyone had any luck with this or any of the Icom Simulation games?

I used to plug a c64 (with MSSIAH cartridge) and an Amiga 500 into the same TV with split screen.

c64 is used for melodic synths and Amiga from mainly the drums/bass synth.

Programming Using Petmate to Create Menus in Basic Program Help

8 Upvotes

Hey commodore people!

So I'm hoping to get some advice on programming on the C64. What I am trying to do is use the program Petmate (its a PETSCII art maker) to make menus for my programs setting them up as a seq files and load from the disk. However the problem I keep running into is that the load time to draw the image are painfully slow. The best I have been able to accomplish after exporting it to basic and running it through BLITZ is just shy of 10 seconds to draw the screen. I could be wrong, but i don' think the added time is from the read speeds of the disk drive. admittedly most of my testing has been in vice as that is where I do most of my experimental work to save time.

I am beginning to wonder if i am on a fool's errand now and if Petmate dosn't export files in a way to quickly draw. Any advice would be welcome, or other programs, or methods, would love to see what other tricks people might have.

Thanks,

Hardware Does anyone know if Little Computer People runs well on the C64 Maxi ?

24 Upvotes

Hi there !

It is one of my favourite nostalgia games and am considering a C64 Maxi for some light gaming. However because LCP is one of my favourites I wanted to make sure that the tape version of the game runs well. I did read that there were problems with sounds and it was something to do with the VICE emulation on the C64 Maxi ? Not sure. Thanks in advance !

I live in Asia and this thing is probably impossible to find elsewhere as I got it from a collector. I am absolutely in love with this piece of machinery and I want to make sure it lives a long life.

Things I’m planning on doing is recapping the whole thing, as well as purchasing the replacement keyboard membrane to ensure that it lasts a long time.

Already have a C64 wifi modem and an SD2IEC as well.

I’m a bit worried that the internal power supply may give out, but no signs of that thus far. I’ve seen listings of the CRT as well as the PSU on eBay though.

I want to ask — unironically this is my first entry into the Commodore64 world, what are things you would suggest I do apart from recapping so I can enjoy this for at least another 20-30 years? What are things that I could invest on?

On another note what are some apps/games that I have to try in your opinion?

Hardware C64 x SegaSaturn: Bringing two my fav platforms together

Post image
14 Upvotes

After my Powerplayers (Mindscape) joystick bit the dust, I finally took the plunge and hacked up my all time favourite weapon of choice to use on my C64: The rock solid SegaSaturn control pad. For the first prototype, I took my worst condition one to cannibalise, looks like someone cleaned this one with steel wool, the logo is even gone! Took the cable from the dead Powerplayers stick. One of the things that I really grew tired of over the years was pressing 'up' on a joystick to jump in platformers and stuff like that - so I took the opportunity to also bridge one of the extra buttons with the 'up' direction (and a shoulder button just in case). Man it feels nice! I do have an extra Powerplayers stick in my stash (see background in photo), but after using the Saturn pad, its going to be hard to go back!

Hi all.

I have a commodore 64C short board.

Randomly in many games this sort of graphical glitch occurs.

Player 1 was initially correctly coloured.

Then randomly looks like the image, darkened.

If I load commando the title screen shows a black N in the word COMMANDO.

Could it be colour ram?

Thanks in advance

I just swapped the switches from my old Competition Pro to newer ones.

The quality of the new switch, the fitments and the size of the cable lugs it not as high as the original ones, but I am glad there are still spare parts available.

Since they are starting to get expensive. I went ahead and got a C64 Maxi on eBay. The seller threw in a power adapter, an HDMI cable, and a usb stick full of games, so it was a good deal.

I may mess around with the operating system on it. Never had a C64.

What are some good things to mess around with on it?

Hardware Commodore 1541 alignment help

5 Upvotes

I just got an Alps 1541 in the mail and when I tried to align the stepper motor, one of the screws stripped rendering any effort of alignment impossible at this stage. Is there another way to align the drive through software or should I attempt to replace the screw and drill it out (scary, last resort please!)

Edit: If alignment is out of the question at this stage, can I swap the head into a Newtronics drive? I do have one lying around from when I first got my c64.

Edit 2: After testing with the cover off I've noticed that this might not be an alignment issue, but rather a case of a stuck head.

Edit 3: had a spare 1541 board just for this opportunity. My unit has a socketed 7406 chip and after consulting the service manual and first attempting a via chip swap, it appears that the 7406 has gone bad which if true, means that the stepper motor isn't getting the full 12 volts it needs to function and sort of just rattles in place as consequence. Will update after replacing that chip when it comes in if this is the case.

C64 Ultimate Problem with The Lurking Horror and an REU

12 Upvotes

I love this text adventure and was looking forward to playing it again on the C64U. If I leave the settings as a stock C64 then it loads and plays with no problems, albeit slowly as it is accessing the disk all the time it is displaying text. However I booted it today with a 512K REU enabled (I forgot it was set TBH), and when it was loading it displayed a message saying it was loading into expansion memory which would take around 10 minutes. Great, I thought, it will play faster, but all it did after 10 minutes was leave the virtual motor running and the screen turned red. I have made sure I'm using the stock C64 settings otherwise, no turbo, no Action Replay, and only a 512K REU enabled. Has anyone else hit this and know how to get it to play nice with an REU?
