I finally got around to creating a simple static website with most of my free games and tools. Play my games online by clicking on the game's image, or visit the corresponding GitHub page. It also lists most of the places you may find me online ๐ 0xc0de6502.github.io

I remember that from looking at the original sprites. The geese going up/down a ladder are equally awkward in size I believe?

Agreed, this is too slow, but doesn't the larger orbit table allow you to vary the speed of the duck more easily?

Ok, this is about as complete as it will get ๐ Here's a preview... I'll tidy up a few things (maybe change the music) and post on Stardot. ๐

I may be able to squeeze in just one more ball on the Elk if I remove gravity and respawn as well (but is not as visually pleasing). Would be numerically pleasing though with 37<<1 = 74

Well done! So the issue is you *have* to use 32K ROMs?

Well done! Isn't some of the tearing caused by sprite flicker? Or are you using 2 screen buffers already?

I have fond memories of that game, so you never know what these experiments could turn into on the humble Elk :)

Hmm, I really can't remember. Your best bet is a message to Dave H on Stardot I think. Maybe the 8K file should be mirrored in both halves of a 16K ROM?
