Oh, wait, I just remembered: It doesn't recognize groups (I've tried it before and it didn't work). Only programs and appvars, I think :(

Yeah, that's why I didn't suggest it :(
graph: here's the source. If it fails to compile blame the fact I reformatted it from Mimas. I can post a commented version later if you want.

He can still transfer page by page, fortunately.
I'll write that program now.
Edit: Here you go :) When you run it, type the page number to dump in hex (no need to press alpha). It will create a 16KiB appvar called PAGEXX, where XX is the page. Note that you need enough free RAM. ;D
Edit 2: Note that the pages for an 83+ are from 00 to 1F
Edit 3: This program cannot dump the certificate (page $1E on an 83+). However, the program GETCERT in the Free83P zip file can.

Whoa, I didn't even see those edits! Whoops :-[

Thanks calcdude! Btw, which pages do I need if all I want to do is get my archive space? 08h through 15h?

Pages $08-$0B ought to be the swap sector, so just $0C-$15 should suffice. However, you should probably dump $08-$0C and $16-$17 as well, and your certificate. That should be enough to reconstruct your ROM (along with $1F from rom8x) as long as your OS isn't corrupted. Good luck!

Me too, I would hate to see Contra and your other projects die, or seeing you having to restart from scratch. Tell us if you got any luck with this!

Btw, you can't dump the certificate without unlocking flash first. ;)

Nope, still dumping ot anothr calc.

As a reality check, CERTIMG should be 3984 bytes, right?

I think it's supposed to be 16 kb (the size of one page)...

Ok. I hope your Axe source can be retrieved.
