It (seems) the cartography room is vital to this ? :unsure:

 

If you empty that room (I did not edit or even go to the 'specials' page) then save the game, you end up with a corrupted file.

 

Interestingly re-loading it back makes JSWED only go to the hex page, suggesting that it is unhappy with some aspect of the game.

 

For what its worth, I merely removed some rooms, the only other changes were very minor such as slight movement of a few fire cells.

 

hmm :unsure:

What format did you save the game in? IIRC, as far as JSWII is concerned, JSWED does *not* (hopefully - yet) support saving TAP files, only Z80. Could this be the cause of the problem?

:)

I re visited this issue earlier this morning. To save potential upset from losing a lot of work ( ! ) , I made a few small changes. The changes were limited to room exits, nothing else.

 

Before closing JSWED, I saved it as a .tap , changed the options to save as .z80 , saved as that, changed the options to save as a .sna and saved it as that. I did try as +3dos but was not really sure what file format it was expecting.

 

Summary is all three do not work. :( I'm at least happy I did not spend ages then realise this again hehe.

 

Using 2.3.7 . I did try with 229 but that does not recognize JSW2 and out of interest I tried loading the 'dud' files back to it, it was not happy but that was expected.

 

If you would like said saved files (sna/tap/z80) let me know I have saved them. :)

 

The only thing is I used the Richchet release (but it is supported from what I can see) simply as that has keypad bypass there (well, kind of) and I had it to hand.

Well, I don't think I can help with this, but do post the files, just out of interest. I'll have a look at them.

 

If there is any specific problem with JSWED, it's best to let John Elliott know about it, as he should be able to address *any* issues that arise.

:) I think the problem is it does not compress properly on save or its not saving them correctly :unsure: I'm not really sure which to be honest.

 

I will try with another version of JSW2 (the original release) but I would expect the same result. If that works then it points towards just the documentation needs an update.

 

EDIT... I'll sort this tomorrow.

Quick test: The original version (the one with the headerless loader) does not work in JSWED as it complains about it being invalid.

 

The Richchet re-release, I just tried loading it into JSWED then saving it as both .z80 and .sna (without doing anything to it) and neither would load back into Spin :unsure:

I think I've sussed this out. Although I need a bit further testing before I post anything (later today) as I think I see the issue now. A minor tweak to JSWED will be needed really to prevent 'accidents'

OK the 'issue' here is you must *not* load JSW2 as a tap file, even though it is accepted and editable.

 

Doing so (regardless of what save type you choose) results in an unsuitable file.

 

To get this to work properly, only load in a snapshot of JSW2 then edit as needed and save (as a snapshot ideally) :)

 

The bug I'm really reporting is I understand that AFAIK JSWED does not support .tap with JSW2 which I can understand given the compressed nature of it, however the bug is it should not really accept a .tap file of JSW2 ;)

This is an important discovery, Andy, and one that John Elliott should be made aware of. I'm not sure he is following the forum regularly - perhaps sending him a PM would be a good idea?

Yes that's probably a good idea. I'm about certain that is the cause. The 'easy' fix (at least to me) would be for JSWED to reject a JSW2 tape file as a source I guess ? Will be interested to hear John's thoughts on this though.
