magicbay had submitted the first fifteen in-game maps of the "regular" areas of SimCity, right from the Map Select screen. From the looks of it, maps from 000-999 would have been selectable, and then anyone would see the map if they needed it prior to playing.
What I had suggested was that rather than expect me to put up 1000 in-game maps of little value (when you consider the site "only" has about 12000 maps total, 1000 just for SimCity is a bit much, and remember, I still manually add these in), it would be more feasible to simply submit 10 images with 100 maps on each if you really want to see the in-game maps here.
Making an image with a size of 2560 x 2240 (which is ten times the width and ten times the height of a single Super NES screen) and then simply pasting in screenshots is not a hard thing to do, it's just whether anyone thinks it's worth doing.
I won't discourage the submission of the in-game maps if they were in groups of 100 so I'd only have to deal with 10 images rather than 1000.
And remember: JPEG sucks for pixel art such as video game maps. You can't simply re-save or convert a JPEG, since the damage by JPEG compression has already been done.
