I have half... the other half have eluded me. Can someone help me find them.

Depending on how far you are, you can do the second championship of gladiator challenges (there is only one set, the previous championship had 3). One of the rewards is the Treasure Mapper gadget. Use that, and when you are in space, and float over a planet or moon, you'll be able to see what you're missing, including the plans. It'll also show up on the planet's map. which is useful.

I am 90% finished with the game, have every zoni, and all but 2 weapons. I have all but 7 ryno pieces...

also with the map it doesn't show me where anything is on the level. No zoni, constructo-mods, or pieces.

finish all the tournaments then find all the ryno pieces cause then you will have the treasure map and the chimpomatic, the treasure mapper should show you the locations in the planet viewer and on the planet map

@ace2ace - That's because you didn't do the Tournaments, like I said >_<

As moogie575 said, once you beat the II tournament, you'll have the treasure mapper, and the Chimpomatic (that's one of the weapons down).

EDIT: Oh yeah, The reward for finishing the gold rank in the first tournament is the Shotgun, at least, the I THINK the shotgun is the final reward, but it IS a reward in the first rank tournament, somewhere (as I said, I think it is the final reward). Maybe that's the other weapon you're missing?

well i have a problem i have all but 1 plan when i look over each galaxy it shows you everything you have(eg.gold bolts zoni) but on mine it says i have all of them.i have the tresure mapper but one thing is there 2 plans on one level like say the last level.

The Great Clock? Yeah, I don't specifically recall there being any plans there, but if that's what it says, that's where they are.

You'll have to backtrack through that game to find em, they'll show up on the in-level map too, so no worries about finding them.

When does the second championship become available?

^Not really sure myself, but I think sometime after:
