CSDb Entries: Release id #261163 : SIDdetector V1.4 /St0fF

Published: April 29, 2026 03:53

Hey, cool release. Just bumped my Interest after finding out on my new C64U, that my 25yr old SID detectors false-positive on UltiSID. Well, what I did at that time was a simple extension of Quiss' method used in a lot of Reflex Demos, checking if the…

Adding some more spice to the receipt: Exorist/Squadron was also a member of The Golden Triangle - a group that released Lunatic and Lunatic II - while Depeh/Squadron later released the famous lunacy demos.. coincidence? :-D

Is this and Squadron the same group? I see Devils Meat is coded by G.SVR/Squadron(France) and 197/Squadron(Sweden) Or did 197 at some point join the "other" Squadron? If so, memberships and credits should be corrected.

I converted one file with Greaseweazle Tools, i also use the FluxGUI with it. It gave a working .d64 file. I don't have time to test some more because i'm going away for a few days. Edit: Tested some more and all worked for me.

C64 Coding: Looking for a certain SX-64 kernal checksum /Korbo

I've been working on a program that performs a CRC32 checksum on your kernal, and compares it to known kernal revisions and mods. However, multiple sources online make mention of an early kernal revision of the SX-64. I can't find the checksum (let alone a…

Quoting SmasherI don't know about CSdB, but it happens in North Korea. The number of votes/voters sometimes decreases. When that happens, Kim gets 99.993% instead of 99.992%. Propably the same reason - account deleted :)

@WVL, do you use the the full petscii keyboard? That one is quite big, and default it renders under or above the input when there is space. if there isn't enough space it could happen the keyboard is rendered above the input. There is an option to stick…

Some thoughts. I needed some dirart and tried this after the xth Dirmaster crash. For me it didn't work too well : at 100% zoomlevel the char selection is (partly) hidden because it is too low on the page. If I decrease zoomlevel to 66% say, it fits, but…

Better run those comparisons on an entire corpus or two. For C-64 purposes, the Bitfire corpus seems quite close to what's coming with a real demo. (Contains fragments of some Coma Light or other, IIRC.)

Repose, there are a bunch of benchmarks over at https://codebase64.net/doku.php?id=base:compression_benchmarks though it's long overdue for an update. 60 cycles per output byte puts you right up there with bitfire and nucrunch for output speed; the only…

I'm pretty sure I discovered something significant. I have an LZSS based packer which is tuned to the 6502 opcodes. It turns out that the entropy is lowest for the 3rd byte, then 1st byte then 2nd byte of an opcode, so if you tune for each byte you can do…

Hi Darklord / Alex, As far I am concerned, the core is open source. After all I used various other open source projects to learn from, so it would be silly to be not willing to share it. It's just not in a Git-repo yet. I am happy to share the "engine"…
