Jump Ultimate Stars Codes Don't Work

[Startropic1]

Several of the codes listed in the CMP usrcheat.dat for Jump Ultimate Stars (NDS) do not work, I have tried them with both the original Japanese version and the English patched version of the game. The infinite health code doesn't work, and none of the gem/"koma point" codes work except for the "infinite Koma Points" code. However that code only gives you infinite RED (ie the first kind) gems, and none of the others.

If someone could help me find some gem codes that actually DO work, that would be greatly appreciated.

Are you sure you're using this code from the usrcheat?

::Max Gems After Battle
C0000000 00000002
020AFF3C 03E703E7
DC000000 00000004
D2000000 00000000

Edit: The Health Code seems to be fine as well.

What modes to you play where the infinite health works? I tried in J-Universe mode and in VS CPU player, both modes I still took damage. I didn't try that gem code, but there's a small problem: I have more than 999 red, green, & yellow gems. 999 is by no means "max." I guess I could remedy that by changing the 03E7 parts to a higher number, but I only want to boost blue, pink, & white. Maybe changing to 000003E7 would do it.

These codes don't work:

Infinite Health [P1 Char 1-4]
021DD104 E1C251B8

Have 999 of All Battle Komas/Stars
920ADAD8 00000001
020AFF3C 03E703E7
020AFF40 03E703E7
020AFF44 03E703E7
D2000000 00000000

Max Gems [Press Select]
94000130 FFFB0000
120B76C8 0000270F
120B76CC 0000270F
120B76D0 0000270F
120B76D4 0000270F
120B76D8 0000270F
120B76DC 0000270F
D2000000 00000000

I took out the first line (94000130) so that the code would come on automatically without having to press SELECT, and still didn't work.

That Infinite Health code worked fine in the first area (Earth).

Try this code:

::Infinite Health
E2000000 00000010
E1D411F6 E1C411B8
E1A00000 EA01E13B
520784FC E1D411F8
020784FC EAFE1EBF
D2000000 00000000

I only tested this in Earth (tutorial levels) and J-Space -> Adventure Galaxy -> One Piece and it worked fine.

Edit: I tested the "Have 999 of all Battle Komas/Stars" and it works just like the "Max Gems After Battle" code. Both codes are writing to the same addresses; the first one just uses a check before executing the rest of the code.
