I wanted to include my hi-res custom panel graphics with Lemminas V1.01, but I couldn't get it to work.
When I first tried it, the graphics did appear, but they were clearly twice the size that they should be, so I resorted to only putting the low-res versions in instead. This is fine, as they do get upscaled/resampled quite nicely by the player.
However, having asked if there was a way to include the HR versions as well, I was advised to add the suffix "-hr" to each of the graphics' filenames. I tried this to no avail.
If, for example, I keep the name "empty_slot", then the graphic appears but twice the size it should be. If I rename it to "empty_slot-hr", it doesn't appear at all.
