You can find a lot of stuff on the archive too. Great full collections even for some systems (NTSC at least as thats what I use). Not sure about other regions.
Quite the accomplishment to take on such a big set but it's a swing and a miss. There is just to much AI upscaling in these and its very visible and identifiable on which files you've had to do this on (which is a lot sadly). Common theme on a lot of your "updated" sets lately. Thanks for sharing, probably better then some of the out dated low resolution stuff but unless done right with the right software and knowledge AI upscaling does not always do a good job.
I also see a lot of pasted nintendo logos, ESRBS, Nintendo quality seals, and the "official game pak" logos pasted on the orginal not lining up so you see double.
A decent amount of boxes do not use true box art either, should probably include that in your about this file section.
100% these are upscaled. While viewing them up close you can see the poor upscale job and a lot of artifacting. A lot of the smaller text becomes hard to read as well.
Are these images AI upscaled? Comparing a lot of these to original scans there seems to be some discrepancies. Just curious 1. the source location for these and 2. if they are upscaled or not. It also looks like on many of the boxes the Nintendo seal is placed over the original/someone else's art and is a bigger size. Sometimes also not in the same location. just figured I would point that out.
