I get to see people studying my work. And, tbh, I'm amazed the details of the cheat mode haven't been common knowledge for years, considering how long JSW128's been out there.
I've managed to download all the pictures (and the messages, though in a JSON format that isn't particularly clear to read). I've also leeched the 'manicminerandjetsetwilly-nonspectrum' and 'jetsetracing' groups, which are the other two JSW-related groups I was a member of. You can find the results attached to this message.

Yahoo are shutting down their groups system with effect from December 14th. If anyone wants to try and salvage the 7234 messages on the old MM/JSW group, now would be a good time to start.
There's some discussion of possible archiving tools at r/DataHoarder. I'm currently experimenting with YahooGroups-Archiver under Linux.
Ah yes, I remember - because an opening wall is of arbitrary height it was easier to do it from the top or bottom than from the middle.
Looking at my original source, there's a comment:
;
;When all segments have slid, change cell attributes.
;
which suggests that I intended it to behave as I wrote it.
IIRC, the opening-wall code is pretty much lifted from the Kong Beast rooms in Manic Miner, so that's the best place to start looking to see what the intended behaviour is.
It means that at least one byte in a location touched by the patch is neither the original one from JSW, nor the modified one from the patch. So JSWED cannot safely apply or deapply the patch.
From the start of the source file:
; Adjacent Ropes patch (second try)
;
; Change all IX+9 references to IX+6
; Change all IX+11 (bit 0) references to IX+0 (bit 5)
