Yes, I know that it's for MameUI and was originally displayed really small. But it's the only existing icon set that I'm aware of.
Even if some of them are not that great - MAMu put A LOT of work into that.
As for non-automated approach, It's "
It may take some work" I'm worried about.
Even with 1 icon under a minute (unrealistic) - all 10k icons would take more than 160hrs. It's like working 9 to 5 for about a month
I know 10k is maybe an overkill, but even if you narrow it down to 3k it's still a lot of work.
That's why I'm aiming for more automated approach.
And regardless of that MAMu icons - for use with FLAT BLUE - anyone can simply copy snap folder (to let's say "icon" folder) and manually make square crop of the game snap to customise icon look. Especially if you have a well-curated small rom set.
