Simple old school hexadecimal editor made in Zig using raylib
It is the first tool from a set created for ROM hacking (any file in reality). A common hexadecimal editor with extra functionalities commonly used in the scene, such as symbols' table and relative searches. The other two are:
All these projects were developed to better learn Zig and raylib, while fulfilling some nostalgia from the early 2000's
The name was pun intended with Ziggy Stardust from David Bowie
A file that maps bytes to visual representation characters
It should have the same name as the opened file, reside in the same folder and has the .tbl extension. So, if you're dealing with ./roms/pkmngold.gbc file and want to use a symbols' table, the file should be ./roms/pkmngold.tbl
The contents of the file are something like:
7F=
80=A
81=B
82=C
83=D
84=E
85=F
86=G
87=H
88=I
89=J
8A=K
8B=L
8C=M
8D=N
8E=O
8F=P
90=Q
91=R
92=S
93=T
94=U
95=V
96=W
97=X
98=Y
99=Z
9A=(
9B=)
9C=:
9D=;
9E=[
9F=]
A0=a
A1=b
A2=c
A3=d
A4=e
A5=f
A6=g
A7=h
A8=i
A9=j
AA=k
AB=l
AC=m
AD=n
AE=o
AF=p
B0=q
B1=r
B2=s
B3=t
B4=u
B5=v
B6=w
B7=x
B8=y
B9=z
It means, for example, bytes 80 (hexadecimal) will be shown as letter A and, when you press A in the character mode, it will insert the byte 80 (instead of byte 41). Also, the original byte 41 will be renderended as a period . to avoid confusion
Each byte and symbol can only appear once
When searching, for example, for DEEP, it will match anything that keeps the same distance between the symbols, like: ABBM, BCCN, CDDO, DEEP, EFFQ, FGGR and so on, also abbm, bccn, cddo, deep effq, fggr and so on
This will allow you to find words inside the file and build the symbols' table to be able to read and modify it easily

- Ctrl + Home: goes to the start of the file
- Ctrl + End: goes to the end of the file
- Home: goes to the start of the line
- End: goes to the end of the line
- Tab: cycles between hexadecimal and character modes
- Esc: opens the menu
- F3: finds next (wraps around the end of the file)
- Shift + F3: finds previous (wraps around the start of the file)
There is no error handling at the moment. So, if you try to open a file that does not exists, or if the computer lacks memory to open the file, program will simply crash and exit
