Both of my hacks use dynamic sprites.
Mario's Strange Quest has 4 dynamic sprites:
- Koopapatrol, which is used in Bowser's Castle
- YI Door, which is used in Bowser's Castle
- YI Arrow Wheel, which is only used in the second half of Mt. Mushroom Cave
- YI P-switch, which is unused.
Use this .srm file to test this out, which conveniently puts you at Bowser's Castle. Mt. Mushroom Cave is found in world 4, and it shouldn't be too hard getting to the arrow wheel (it's found after the goal with the missing goal tape).
Yoshi's Strange Quest only has 1 dynamic sprite, which is the Giant Tap-Tap boss. You can find it by playing through Ruined Castle in World 6, or better yet, going into Yoshi's House, touching the green ? block, then heading left and entering the pipe that takes you to the boss rush version of it.
Here is an .srm.
Although, I have tested YSQ with an SD2SNES flashcart and I didn't encounter the glitches you were mentioning. As far as I know, wouldn't $0660-$067F potentially get written to only when the level ending circle HDMA kicks in at level end? YSQ doesn't end the level when the tap-tap is beaten, but instead teleports you. And none of MSQ's dynamic sprites are found in a sublevel containing a goal tape/sphere.
Also, speaking of the tap-tap boss,
An SMW Central Production uses it. I think it was in the castle before Bowser's Castle.
.srm link ASMWCP might use other dynamic sprites, but that's one that I know it uses.
