Porting HBL by hands

[wololo]

When you have the UID (0x04AB0431) you need to find it in user memory. The position where you will find that uid value is the FREEMEM_ADDR value you are looking for.

Also, just to state the obvious, your uidlist and your memdump must be done in the same game session because UIDs change everytime you restart the game

know but I use just

Code: Select all

modinfo @name

.

host0:/> modinfo @mod
UID: 0x04AB0431 Attr: 0000 - Name: mod
Entry: entry_addr - GP: 0x00000000 - TextAddr: 0x08804000
TextSize: text_size - DataSize: data_size BssSize: bss_size

I want entry_addr? It is in a umem, but != addr founded by tool. What is not rigtht?

[wololo]

it is not entry_addr

m0skit0, I guess what we can't use "move" with the stack operations.

m0skit0, I guess what we can't use "move" with the stack operations.

Code: Select all

sw $src, $sp(imm)

pushes the word contained in register $src into $sp + imm

Code: Select all

lw $dst, $sp(imm)

pops the word at $sp + imm into $dst
If this is what you mean.

should be correctly..

pushing:

Code: Select all

sw $src, imm($sp)

pops word:

Code: Select all

lw $dst, imm($sp)

Yes, sorry, I totally messed that up

[m0skit0]

Yes, it's LW and SW instructions, sorry

hmm.. and user_main also? I guess what loaded h.bin stores in user_main thread.

I don't remember now if HBL is spawned in a new thread, but I think not, since we had problems doing so. So you're right, user_main should not be killed.

We *do* spawn a new thread, and yes user_main needs to be killed, but not before the hbl thread is started

A jal to entry of loaded module should be fine. I've tested that. So it's not necessary to start a thread to run loaded module.
