Moon jump ASM for 3d games

lol really? awesome.

I'm now back on Eldar Saga.
See post

Now that I can find the addresses properly, I can start working on eldar saga again.

bl is not a conditional branch.  it's not a "branch less than".  That's blt-

bl is an unconditional branch.  It always takes the branch regardless of the CR.  bl = Branch and Link.  It is just like a normal b, except the address of the next instruction is placed into the LR.  This is why mflr gives us a pointer to the data.

Ok but isn't the mflr for moving ASM datas? And what does the bl branch exactly do?

lhz r12,0(12)
andi r12,r12 0x3EF0
blt- THE END
---ASM DATA---

THE END:
original instruction

The bl will branch in the 4e000000 that is loaded.

[dcx2]

The bl will branch over the 4e000000 that is loaded and put a pointer to the 4e000000 into the LR

For what is the Link Register? Why couldn't it be done with just standart instructions?

[Patedj]

it's just easier this way no, deathwolf?
Anybody have de Blob 2? Moon Jump on de blob2 seems to be quite complicated... I've been trying to figure it out... they are all wierd...

"doesn't work"?

Freezes?

Does nothing?

Does insane things?

[Patedj]

Does nothing.
