Strider is MFM as far as I recall.

There's no need in fact, they have buried the files as it is directly in the MFM encoding.

More straight port, you can't beat that lol !

How ST manage the unaligned sprite? Or suffer also garbage on screen like the Amiga version?

Yes MFM, but is really simple to extract the hidden files (loader at $988);
the VT DOS/0 cracked version contain files named like 000000xx, where xx is the indexer used in original loader.

Do you have also IFF->PC1 converter?
My goal is a full PC1->editor->PC1 just to be fast but even a double conversion is acceptable

grafx2 works as expected but with a problem: repacked file are ~2K bigger so there is some floppy space concern..
I have not checked if he messes up with the bitplanes.
Maybe I'll rewrite a Packbit for the body part of Degas format. or make my format.

=> they are yes, exactly the same.

i don't know for the unaligned sprites. to be honest i have not seen the strider sprite bug.

What do you need ? PC1 files, CHR files or PRG.BIN ?

If files i've are not damaged i'm fine. I've attached a txt with their md5 checksums.
But if you can upload all yours ST ones to the Zone!, I can double check them
Thanks.

Well, like usual I do not have much free time (and the weekend has flown) but I see what I can do
I usually try and support a cleanly cracked game if there is one, but in Strider's case the versions out were probably all so butchered I didn't bother. Many of my installs support the Quartex cracked versions as Robin cracked them cleanly so the disk images often match what you'd rip from the WHDLoad one.

I am happy to add your fixes into the WHDLoad version and/or send you the source if you need it.

I remember seeing this before. I wasn't sure if it was the first game or the sequel.

Interesting.
I took some time to extract the files from the original disk (I did not totally believe in this cracked version, that's why I asked Denis for a double check).

And there is some difference:
- files 4b, 36, 64, 72, 85 have few different bytes;
- file a1 is really file 97 (and on this I would have bet since the game does not use 81 tracks);
- 9e is really file 94 (another easy bet because cylinder 79 is the "protection", a simple low/upper tracks unbalanced written bitcells speed check).

So cracked files 94 and 99, the Degas 32066 bytes PI1 files with zero-forced header color data, are not used (anyway they contain garbage).
Where did those files come from? A different version of the original disk? A prerelease? An error in data extraction?

Attached md5 from original files.

[EDIT:]
Buried somewhere there are also original Amiga files names,
in sector position order, so is simple to reassociate.
Code:
bstrider.prg
graphics/amsht1b.pc1
graphics/amsht2b.pc1
graphics/amsht3b.pc1

Ok, I took a decision on it.

Because:
- all "files" versions are based on Vision Factory crack that surely is from a pre-release or a leak (code/structure/raw data are somewhere different from retail),
- Quartex crack have some timing problem,
- Flashtro crack is a bit bugged and visually glitching,
I'll do my (little)enhanced cracked/trained ADF (and a successive WHDLoad version).

In the meantime i've fully patched sprites errors (a pain..).
I've even partially redraw a frame by hand, there was no alternative.

I hope this also does not pile up with other unfinished stuff

Might I suggest that if you're going to do that, do Strider 2 at the same time and stick them on the same disk?

Both compress to fuck all.

Did like the arcade version but not so much the Amiga one...
However a game having the "ross touch" is worth a rethink.
