Hi,
For dumps, Red means no dump, yellow means incomplete or underdumped and green means a good dump from an original source.
For Scans and screenshots, red means none of them, yellow means incomplete (we have scans but no screenshots, or no scans, or no quality scans...) and green means quality scans and screenshots.
Finally, for the wiki page, red means it doesn't exist, yellow means incomplete (though rarely used) and green means a complete page.
The ideal would be to have scans of everything, from inlay to tape, to hardware boards, etc. For standard tapes, a scan of the inlay, the manual and the tape is the way to go. I usually do them at 300dpi resolution, but beware that if the resulting file is bigger than 2MB, or any dimension is greater than 2000 pixels, it will not show correctly in the wiki.
Screenshots are 640x480 screens taken from Xroar.
We have also permissions from several publishers/author to link their software, you can check that
here. In any case, dumping the software we don't have already is mandatory if we don't want to lose it forever, and in in doubt you can ask here first.
I also want to thank you for offering your help, as there is still a lot of Dragon software not preserved and any helping hand is quite appreciated!
Regards,
Rob
