I was wondering are there any hacking related documents on hacking for the Sega Master System in general like for Hacking Text and etc, all I can find is either game specific or details of the system's spec's.
Text hacking is basically the same thing as other systems. Use relative search to find text (or MEKA's tile viewer to see the font). The mapper used in most games can swap banks in $4000-7FFF and $8000-BFFF (some games use a variant that allows $400-3FFF to be swapped, leaving the first $400 bytes in the swapped bank unused). So that would mean typically pointers would be within that range.
I think tile editors usually support that graphics mode.
If you can't find the graphics then it's probably a compressed and you have a game-specific issue (although I think someone on SMS Power made a program to detect common compression formats).
