Limitations for sideborder sprites

Hi,

I'm doing some recreational coding and hit a small bump. Now, It's been a long time since I've done any serious sidebordercoding, but shouldn't it be possible to have 4 sprites in the sideborder while still having text (no d011 fiddling)? Right now I'm out of time for the badline so maybe it's not possible or I am not using the right sprites? (remembering there's some limitations depending on what sprites you use).

Would some kind soul enlighten me on the subject?

Thanks.

just forget the limits, Trap! limits are there to be broken, no need to be scared.
show us you can do 8 sprites in ze border with BL and no $d011 or REU tricks!
you do that and I hang a poster of you in my room! :)

Just say the magic word: Impossible! And crossbow will appear in cloud of smoke.

Ok, stop kidding. Mixer is right. You can do 4 sprites in sideborder with badlines, if you avoid sprite 0. Took me weeks of try and error to realize this back in the days.
