Hi guys,

I'm currently working on hacking tools for SEGA Mastersystem for my emulator Emulicious (http://www.emulicious.net).
There are 2 tools so far:

A memory tracer that can tell the sources of data (see screenshots)
A smart (seperating code from data) configurable disassembler

For example by following the source of tilemap data one can easily alter/translate texts of a game (see screenshot). Or alter images/palettes following the source in the respective viewers.

The disassembler can already completely seperate code from data in games like Alex Kidd in Miracle World and Sonic The Hedgehog 1.

Kind Regards
Calindro

Hi guys,

I'm working on a debugger with syntax highlighting.
You can see the register values in top right and the stack below of it.
It allows 3 ways to step:

Step Into: Steps to the instruction that will be executed next
Step Over: Steps over the current instruction
Step Return: Steps out of the current function

I could have used this a few weeks ago when hacking Royal Stone

I am actualy using the memory tracer and i can say this is really cool !

Hi guys,

I've just released a new version of Emulicious with the mentioned features!

Check it out on http://www.emulicious.net

Enjoy!

Hey guys,

there's another update of Emulicious!
This update mainly involves updates to the tools

I've added a Memory Editor with the following features:
datatype highlighting, informations about sources (provided by the Memory Tracer)
The names of the registers (also the VRAM Address) are annotated at the addresses they point to
Follow registers (select a register that you want to follow with your selection)
Save changed rom as romfile or changes as ips file
Undo/redo

The profiler has been improved:
You can now profile code from one point to another by providing a start address and an end address (e.g. of a function)
The data is provided as min/max/average

The tracer has been improved:
You can select the registers you want to trace and optionally provide a start address and an end address to limit the trace from a point to another or just start the tracing from a specific address for example

Any plan for a search in the memory (supporting both hex and ascii)? (Or even table support?)
What about memory breakpoints - is that in the plan too?

Hey guys,

I've just updated Emulicious!
The new features include:
Use table files with the memory editor
Search for hex/text in the memory editor
Watchpoints (aka memory breakpoints)

Hi guys,

I've just release another update of Emulicious.

The new version comes with several new features:

A Find Dialog for the debugger
Trace Highlighting (highlighting the instructions that have been executed before the current one):
A Reference Hierarchy (showing all the references to a label):
Destination Highlighting (when hovering a control flow instruction the destination gets highlighted; CTRL+Left click on one of them will scroll to the destination):

I won't use your soft because I'm more in MD hacking, but this looks awesome. Really.

Hey by the way are these tools useful for porting games from Game Gear to Master system?

Hi again, I've just downloaded Emulicious and KiddEd and both are great!!! do you mind giving me some tips please.? I want to make sprites to appear outside the center screen (160x144) for Game Gear games X-men & X-men Gamemaster's Legacy and more. I'm new in hacking (I made some widescreen hacks for PS2 and I am familiar with C++ & Java programing besides I'm willing to learn more:))
Greetings

At first you should enable the Memory Tracer and open the Sprite Viewer. With the Memory Tracer enabled start the game and play until sprites disappear. Now pause (CTRL+P) or suspend (Open the debugger if it's not open yet). Hover over the sprites with your cursor and look out for the lines saying "source...". The format of the source is as follows: ROM/RAM [source of data in ROM/RAM] (ROM/RAM [address of the instruction that has loaded the data from it's source])
Now open the debugger if it's not already open and press CTRL+G and enter the address of the instruction that has loaded the data. Now you need to understand what the code does so you can alter it to prevent it from removing the sprites that go offscreen. To alter an instruction you can right-click on it and click on "Select in Memory Editor". In the Memory Editor you can change the bytes that make up the instructions (a table of byte value / instruction can be found on http://clrhome.org/table/. As reference for instruction behaviors you can use http://z80-heaven.wikidot.com/instructions-set). When changing bytes in the memory editor you will see the instructions in the debugger change accordingly (this way you can verify if you've written the right values). When you're done changing altering the code to your needs you can test it by resuming the game. When everything works as expected you can press CTRL+S or File->Save As... in the Memory Editor to save your changes as an ips patch file or an sms/gg romfile.

Hi guys,

some people have reported issues downloading Emulicious. These issues have been solved now. If you still have trouble please let me know so they can be solved as soon as possible.

An update of Emulicious has been released!

The debugger has been expanded by an outline which helps you navigate through code and orient yourself in it.

The tracer can be controlled using conditions now. You can define start/end conditions and a condition on which to trace an instruction at all.
Additionally you can provide an expression to be evaluated before each instruction being traced. Its result will be appended to the trace. This way you can log additional information. For example if you want to watch the value in RAM at $c100 you can set the expression to "@$c100". That way each line of your trace will also contain the value at $c100.

As usual you will get the update via the auto updater or the full version from http://www.emulicious.net
