Did you know the Commodore 64 Ultimate can display Atari ST pictures in the original palette colours and 320x200 pixels resolution?In fact, in many ways the ...

Making the C64U do more than purple and brown really makes a difference to the result for sure :)

#AfternoonDubloons!

Bear with me! Ladies and Gentlemen:

WELL COME BACK - We have a WINNER!

I have spent a little time on the C64U this afternoon, when I should have been working, to see if the world really is turning a corner - it seems like it is! BRAVO! #C64

やっぱC64Uですかね。
SIDチップ2個刺せるスロットあります
ので、SIDエミュと併用しても単体でもそのまま使えます。
純正でもエミュでもほぼ違いがわかりませんがw

Just made one working datassette from 3 broken ones for my C64U and I’m feeling quite pleased with myself. Nothing beats the tape loading experience 😂 #Commodore64 #datassette

Nice work!

How does the "speed cap for fast CPUs" work, and should it stabilize the game on a C64 Ultimate at 64 MHz? In a quick test it didn't, and the entire game speeded up to unplayable, but maybe there are some limitations to it?

(64 MHz C64U could probably handle 50 fps filled vectors...)

As you all likely know @pacbilly.bsky.social and I are both avid Bard's Tale fans and indeed The Bard's Tale 1: Tales of the Unknown, we have both completed.

This save tape, my friends, family and candle sticks, is THE party that I used about 35 years ago to beat BT1 ON FRICKIN' CASSETTE!

The Commodore 64 Ultimate can do things a regular #c64 can’t …

For #RandomGameSaturday here is Fairlight for the #C64 - a game I probably would not have got on well with in the 80s. My partner @angel-mhor.bsky.social has very fond memories though. On the #C64U you can crank the CPU up to 2MHz and then it feels a lot more smooth.

Thinking about buying a c64u starlight and a spectrum next violet transparent (if it's possible) next year.
Imo. Iirc.
Lately I really want to revisit old games and push their limits.
If possible.

Oh wow!! Aw man this is wild to imagine but holy cow I can't wait to see the c64u on store shelves here! I already have one ordered but wow!

#AfternoonDubloons! A new (old!) game released for the humble #C64. This is actually a really neat racer. Plenty tracks, a bit slow, but lovely detail and that Title SID, whoa! That is wicked up loud! The SID is borked on C64U, hence - VICE VID. Anyone got a C64U Fix?!!?

@commodoreofficial.bsky.social any idea (ballpark) when C64U will get the 3.15 based firmware? A few features I am excited to include in my code :)

Is the SID emulation not very accurate on the C64U?

The #commodore #c64u #ultimate can do so much more. Here is a video that is from a game in the making called MORTAL COMBAT 2. You might have heard from the franchise. It's running on the FPGA 8-Bit machine, and it's looking great! ...
