It's outside of the visible part anyway. I'm quite sure that of you use R#23 to make that part visible (or force 212 lines) that sprite on Y=209 will be visible again as well. At least the V9938 application manual doesn't say anything about that and neither does the TMS99x8 application manual.

uh, no beef. Thaz the funny part. it DOES disble the current sprite!
If you check Aleste (msx2) (for example); while scrolling don't move and once in a while (depends on scroll speed eh) you'll notice the main sprite character (the fighter plane, duh!) jump up and down 1 line for a brief second (again depends on the speed for obvious reasons)

Other games I could mention have the same, so that's some proof. Further more I have tested that theory once (quess the results ppl, no buckaroonies for you this time!)
little stupid thingy, but hey.. gotta live with it.

That's line 216 it skips, not 208, 209 or 217. And you say you've done everything with sprites already?

yeah, been there done that. liked it, survived it.
oh, 208, 216.. 6143.. whatever. thing is the "put the sprite on me to make it in hiding"
Y position is really hiding it. That's what we're talkin' bout right. else you just put sprites on non visible Y positions (as you mentioned) ah well.
I'm a bit rusty on some specs, but the sprite crap is clear in mind.

One thing I HAVEN'T done with sprites is shoving them up YOUR tight ass, beef! <- big smiley

Oh yeah, as if that's gonna help.

Even though all this side-topic stuff is a lot of fun, it doesn't help IC either with his problem I think.

topic? what was the topic again? , aah yeah. Well, Think we've baffeld enough specs here for him to figure out his lilly prob. My quess he's just putting 2 sprites over each order in order to create a 3-colors-on-1-line sprite. Haven't seen him all day, better let him test all this new found wisdom. tattaa!

IC you speak(read) Dutch? I'd send ya the docs I wrote years ago, might help you out on various sprite questions. .. Eh that is, if I can find them again... sure.

I saw some articles about sprite of somebody called 'Ro'-Man at SRS #4 (iirc). It freshed up my memory somewhat.

And If you have additional documentation about sprites, they are absolutly welcome here (even In Dutch! Cauz I can Read it, Write It and Understand it . )

Would be cool to have a copy of these articles coming my way as well. Very curious what you have found out more than we already know.

yeah Beefman, did some collision test but never used it though. I've written a complete animation engine for Nosferatu and Fubsy which includes Hard- & software objects (sprites and real-gfx) so the build in sprite collision bits would become absolete anyway.

Indeed the SRM texts were from me (ro-the-man if you want..lol), I've upgraded/added much on those file in the years though. Also got some in-depth specs about using the clockchip, the mouse and joystick. I will see if I can dig'm up and translate it and publish them again (I'll send you a copy beef)

Eurm... Back 2 topic -> I've made myself a lil' test game in NBASIC (ought to finish sometime ) which uses R#23 to scroll the screen. I let my race car 'jump' over line 208, and tatta! There's no blittering anymore. So the ish about the line 209-sprite disabling can't be verified. The sprite's just staying there, not being disabled and such!
