Commodore Format Archive

I let a Commodore 64 run for three and a half days straight. 87 billion instructions, 303 billion clock cycles, 5.9 million candidate settings tested. It cracked an Enigma message in German without knowing a single character of the plaintext. 🧵1/2

September 1994: A fantastic request in the Wanted section of CF 48’s small ads. Wonder if he found one? 🙏🏻

We are so sorry to pass on the news that #RedDwarf co-creator @realrobgrant has passed away. ganymede.tv/2026/02/rob-gr…

Terribly sorry, but with spelling like that the deal is off.

Unexpected item uncovered in Crystal Kingdom Dizzy 😅

Flash back to 2019 and our interview with @CommodoreFormat commodoreformatarchive.com/the-chip-sid-s…

@SFXmagazine @paramountplus @ParamountPlusUK 400! Congratulations guys. The last truly great mag to have come out of Bath. It’s so cool you’re still here.

SFX 400 beams down on 31 December, featuring the cast and creatives from new #StarTrek series #StarfleetAcademy 🖖

This proves why the 40+ year-old 8bit Commodore 64 chip was ahead of its time: #chiptune 🤟

@bozwaldcoblepot Yeah, so here’s a thing. Nothing is broken. It just…fell off. It wouldn’t slot back on, but when I removed that red “collar” and tried again it snapped into place and works fine 🤷‍♂️ Obviously not how it’s meant to be, but it’s working again.

@CommodoreFormat Hard to tell from the photos, but it looks like maybe it's supposed to screw on? Maybe if you open the base up you can access the nut and tighten it?

This happened to my micro switch joystick for TheC64…anything worth doing to save it? It hasn’t snapped, just detached. Still works but keeps falling off.

@fgasking good afternoon, Frank.

#C64 scrolling test #6: It now also works in NTSC and it can scroll in 1-pixel steps. (the old version only used 2 pixel steps) There's more to come, stay tuned!

Real ones who’re here for CF know.

🧠 I think of The Mighty Brain whenever I pass this place.

❤️ It’s now 35 years since issue 1 of CF went on sale 😱 👌🏻 In one of our personal favourite pieces from the Archive, deputy editor Sean Masterson tells us about the road to launch: 🔗 commodoreformatarchive.com/the-sean-maste…

And thank you all for your continued support. The site might be on hiatus but it’s going nowhere. The traffic and new fans we get each month speak of the magazine and the C64’s lasting power.

IM3 - game wise everything is now in there - we are now tweaking gameplay and fixing a few things that dont work so well. All the ingame sound has been done, we just need to see how much memory we have left to see how much of it we can fit in it. #c64
