Ok, apart from the ones here, anyone have any ideas if there are more?

Having spotted that one Venom is Inspekdah Deck, I came across a couple of other Venom', i.e. Swedish(2) and Finnish(1)... Now sorted...

Got one Venom (Matt Peters) with the MC5 Rookie entry "Sustained Desperation.it". Anyone know if he tracked other songs or heard of him?

The last Venom has roughly 16 fairly hq xm modules to his name. Usually credits his name with \/enom or l/enom, and called Oskar Janssen with a hotmail addy. Possibly d/l from TiS in 98/99, so no idea where they came from.

I don't like including RL names, is there a way to Spoiler alert them for future reference?

You have it right. The header is 100% identical to Protracker, so ... yeah, that's nice
There was no indication. or even mention, of this packer or its author within the prods. I tried to widen the search to prods that were released in the same span of time (~1991). To no avail. Although, you're right, TKB is a likely candidate indeed.
So yeah, please, reach out to any Devils member and report back

All,

 I've recently spent some time on an unknown (to me) protracker clone format. I don't know the name nor the author. The material is found only in Devils prods, so .. I've made up this very original name "Devils replay"

 I started looking at this when handling this No Reality demo by Devils. Rather quickly, I found that it's the very same format as found in Colors demo, also by Devils.
 Cybfree, once again, quickly reminded me that this format was already beaten - more precisely, the musics from Colors were already converted. Great !, so, I can write a quite converter myself for the others.

 That's exactly what I did. It took me 3 days because I'm still not great at coding, but it's done. So, first, all the cases found are here:
http://janeway.exotica.org.uk/release.php?id=752

 The format itself is somewhat unique in that it does things I've not seen elsewhere. Promizer could be a distant cousin of some sort

standard protracker header until 'M.K.' at 1080
1084          short         size of pattern data [A]
1086 + [A]    short         size of reference table [B] - must be at an even position
1086 + [A]    short         sample data
+ 2 + [B]     

pattern data:
192 bytes per pattern
3 bytes per row:
 0 byte : filter
 1 short : address to read in reference table

Reference table:
contains rows of output unpacked notes - so up to 16 bytes.
depending of the filter, above, the blocks of word/short are stored
filter : abcd-efgh
output: in 16 bytes
B1 B2 B3 B4 B5 B6 B7 B8 B8 B10 B11 B12 B13 B14 B15 B16
|  |  |  |  |  |  |  |  |  |   |   |   |   |   |   |
 \/    \/    \/    \/    \/     \ /     \ /     \ /
  a     b     c     d     e      f       g       h
if the filter bit is set, the corresponding output is stored in the reference table.

 I guess that's it. No sure I was too clear on this one. Please, report back if you want more details.

 Again, huge thanks to Cybfree for the help.

I hope this could happen with Jogeir Liljedahl too. 

And Purple Motion, Lizardking,...... 

This is really fantastic. Thanks a lot Curtie.

I hope this could happen with Jogeir Liljedahl too.
