Actually it's been around a while. It crashes because Apple doesn't agree with Unicode.
Edit: To clarify it is a bug, Apple isn't just being stubborn. I wouldn't put it past them to try to create a brand new format though.

I've been digging into the world of OS development for a little while for the fun of it.. Got your basic 32 bit kernel with IDT/GTC/IRQ, keyboard input, etc. No paging, user stuffz, or file system though.. Super basic but still very fun.
What have you guys done? Show off to us, I'd like to see what this forum has to offer knowledge-wise in this area.

Sorry for being a noob here. But how the hell did you get the information by reversing it? I tried reversing a simple building game and it was 20,000,000+(decimal, not hex) lines of code. Was there somehow a way to jump to the more interesting code?

Well when I start reversing a game I look for a basic value in cheat engine. Take health for example.. Do a search for it in CE and do your everyday change, search again, change, search again technique. Then look for accessors of that point in memory. Say you find this accesses it:

mov r11, [eax+10h]

Well, obviously the last offset is 0x10. You then search for whatever eax is at that point in time (debug/breakpoint it) and do a search for it, dereferencing. Then check what accesses that. You build a whole pointer list up until you reach a static address, and then you know that's probably the base address of the game if it's something like health/money. For more complicated things you can dump the game and inspect it in IDA, and reverse the data structures and virtuals from there looking at the virtual tables and stuffs. It takes time to learn.

I'm going to upload all the code for my hack at some point. Maybe during the summer. I'll exclude the SDK.
Or I may just upload the memory lib. Don't have much time on my hands right now, AP tests are killing me.

I'm still working on this project. I've added a bunch of shit, including teleportation and pseudo flying. Calling some virtuals for raycasting using a stub because it's an external hack. I also have a 3D radar view (top down, renders basic player models in wiremesh I made) using some directx trickery. Fun stuff

Which just means that they(you ) will have to figure out how to make your hack undetectable visually.

Well there's a reason I render everything on an external overlay
On a little chams test I was doing using some code I found online, I had to create a simple internal hack (dll injection) to render the chams correctly ingame. Since it's an ingame rendering thing I had to hook into the anti cheat screenshot method to send a black screenshot. The anti-cheat doesn't do anything about black screenshots because they can be caused by bad drivers, so that's one method if you're using engine rendering.

Yeah this information is pretty much copied off the video. But it's pretty common knowledge too.
This is nowhere near how actually creating game hacks goes though. If you're developing other things, anything other than local value hacks, you will most likely need to dump and analyze it in IDA or something similar.
Good luck attaching a debugger to a heavy game like Battlefield or COD, in multiplayer.

If I were OP I would go over more in depth reverse engineering, like finding vtables and reversing data structures, because these are the important things. No need to jump into DLL injection before they even know how to find a virtual and reverse it.

I could help. I've experience. PM me if you want me to contribute on your tut.
Be careful, there are many many beginner reverse engineering tutorials using Assault Cube, no copy pasta.
Also, there's no need to go internal for things like no recoil. If it's in memory and isn't a virtual function, you can access it. Of course you could reverse the virtual funcs but I digress.

You can also go the C++esque route and store the result in the variable you passed. However that's going heavily against Java conventions AFAIK.

So you're using Java2D, a software renderer, to create an 3D game.. Is your teacher batshit crazy or is he trying to teach you mathematics?
It's totally possible, I've done it before and it can be fun but it's not practical in the least for a real game.
