Amazing Disappearing Pink Ball Glitch

[tensorpudding]

I'm curious to see how the 48x48 glyphs look. I can't figure out how to make the partially-transparent tiles look decent, trying to upscale them from the 32x32 set. I'm using hqx to do the scaling since it works well for pixel art, and the end result looks great if you have alpha support, but if you try putting it into the tile world bitmap format it gains a nice halo of magenta. I tried converting it directly to a bitmap after scaling it, but before replacing the transparency with magenta, but then the tiles are all malformed, with bulging outlines. And of course I'm not good enough at drawing to trace and draw new pixel art in the bigger size.
