I'm not 100% sure if this should be posted here, but it looks like Invincibility, Always Maximum Shot Power, Always Shoot Charge Shot and Lock Energy Charge are either buggy or don't work.
Invincibility, when activated for PL1, causes the ship to go completely offscreen. You can turn off the cheat and it will eventually come back from the bottom of the screen. Always Maximum Shot Power locks up the game. Always Shoot Charge Shot and Lock Energy Charge don't work at all - in fact, it appears they keep the ship's gun from charging at all.
The same behavior affects PL1 and PL2. My apologies if this shouldn't go here - couldn't think of anywhere else to put it, since its not a request or a completed request.
EDIT -- Forgot to add that the bugs are in MAME 0.123u1.

Thanks, fix (Normal Location to Program Space location) here:-
viewtopic.php?p=9640#9640
Unfortunately, this is not an isolated incident - I think all the other games in the nmk16 driver will likely need this fix (44 games in total).
Might have to do a cheat file release quicker than I thought

No problem, should really have been posted in cheat requests, movedI'm not 100% sure if this should be posted here

I had a chance to go back and test the other nmk16.c games potentially affected by the MAME change - it turns out that only a handful were affected:
Black Heart (blkheart)
Sen Jin - Guardian Storm (grdnstrm)
Stagger 1 (stagger1)
Super Spacefortress Macross/Chou-Jikuu Yousai Macross (macross)
Task Force Harrier (tharrier, tharierj)
Twin Action (twinactn)
US AAF Mustang (mustangb, mustang, mustangs)
Interestingly enough, they all behaved in the exact same way that Red Hawk did. The rest of the games on the list play just fine. Hopefully that makes the update process a bit easier for you!
