PPC Emulator (WIP)

[Romaap]

I will be trying to make a PPC Emulator.
What this application will do is emulate the PPC like a real Wii.
With this it will be easier to debug ASM codes. (it will be more like an ASM Debugger than a PPC Emulator, but PPC Emulator sounds more awesome)


Download it Here
It has an auto-update function, so every time you start the application it will check automatically for updates.

Source is found here.


At this moment it supports the following OPCodes:
lis, li, addi, add, addis, and, andi, andis, mr, not, oris, ori, slwi, srwi, subis, subi, sub, lwz, stw, lhz, sth, lbz, stb


To-Do:
- More OPCodes
- Better warnings when the OP is invalid
- Alter the Condition Register when needed (it doesn't do that atm)
- Branches
- Some bugfixes
- More cool stuff
- Using RAM dumps (?)

Awesome. I'm looking forward to seeing it expand! =D

[Bully@Wiiplaza]

great, you do a RAM Dump and then debug the game without doing it live on the Wii *_*
But will be able to see, if your code worked or just if it crashed/not crashed the game? :confused:

This way you don't need the wii on to debug a game. I like it. Eventhough I can't do ASM :(

So what do you guys think of this, and do you have any suggestions?

Its pretty neat idea, good for learning PPC asm.

this will be useful when completed... do want :o

[Romaap]

Updated :)

See first post.

Skiller had a good idea a while ago...make it so you can load a RAM dump into the disassembly tab of Gecko.NET so you can poke through ASM without the game running.

It might not be a bad idea to fork the disassembly tab from Gecko.NET and into your Emulator.  It looks like you're using .NET, so that wouldn't be too difficult to do.  Do you plan to open-source your app?

BTW, stw r1,0(r0) wouldn't work the way you're trying to make it work.  stw is one of those (rA|0) instructions.  That means that when rA = r0, it uses the value 0 instead of the value in r0.  Therefore, your stw is actually writing to address 0, not 80000000.

Thanks for the reminder.

And that's definitely a good idea.


I added the source to the first post, but beware of the wasteland of randomness.
I'm not that much of a 'clean' programmer, but I tried my best to keep it neat this time.

O0 Love your magic! You were my first mentor.
I'm really hyped, could you do a clip for it? It would fit perfectly with your previous clips.

Awesome work Romaap, I'm also looking forward to where this is going.

THis kinda thing would be great to add to a Load Dump kinda function it would alow u to check the asm thats in the game and as well debug the ASM u build .. Making sure branch functions are working right and alow u to build branchs alot easyer :P B 0x8000a000 ahh nice :)

nice work will for sure check this out ..

[stormshellx]

this is pretty pointless if you cant load ram dumps....

[James0x57]

You're pretty pointless if you're not contributing and talking shit about things you know nothing about.

I'll go ahead and take care of that though. *bans*
