OK, I'm gonna keep this quick and simple. For a while now, the Gold/Silver Lost Pokémon page used some simple versions of the sprite image files, and because of which, it didn't really look nice when rendered on the site. Also, since the images themselves varied in size, and I posted them on the site at the same size regardless of their original size, it made for a look which was somewhat blurred and inconsistent.
Case in point, this is what the Gold/Silver Lost Pokémon page looked like because of which:
Notice all the different sizes for Chikorita and... uh... "Bayleaf"? Like, how big is Chikorita supposed to be in-game? Or how does it size up to its evolution? Oh and if it's supposed to be pixel art, why is it so blurry?? This was what I wanted to fix.
So what I ended up doing was basically going through every sprite image and fixing them up so that they're all crisp, pixelly, and consistent. It might have made them look a bit smaller, but I think ensuring every sprite image is the right size, both for the Pokémon itself and relative to every other Pokémon.
This is what it looks like NOW:
Pretty awesome, right? Look at how crisp everything is! And now we can see how big (or small) Chikorita is relative to its evolution, to say nothing about how its Proto-Evo sizes up to every other Pokémon. Huzzah! Good times.
Fortunately too, I was able to batch automate the necessary edits through Photoshop, which definitely saved time. Like, if I couldn't automate the process, then I wouldn't have done it at all. Furthermore, some of the sprite images HAVEN'T been corrected, mostly because the files were stored elsewhere and I wasn't able to fix them during this initial run. But like 95% of them are done, and that's what matters. 2x "Huzzah! Good Times." Multiplier!
And that's that! Hopefully it looks better on your end, especially if you're looking at it on a mobile phone, or have your browser window zoomed at either 100% or 200%. But if you're one of those weirdos zoomed in at like 133% or 175%... sorry, can't help you there (frankly, it looks like you're the one who actually needs help).
Post-posted post update:
I forgot to mention that, during my recent offline time, I had discovered that the Pokémon Diamond/Pearl betas were leaked, complete with several "new" prototype designs for existing Pokémon. I have contemplated adding them to this list and therefore changing it to be simple "Lost Pokémon" versus it being specifically about Gold/Silver Lost Pokémon... but I dunno. I might just make a new page altogether.
I WILL, however, be including the Diamond/Pearl prototype Pokémon to the "Space World" fake card set... there is ZERO reason not to!
