Rebelstar - 1986

[Border_7]

This was (still is?) one of my all time fav games (behind Into Oblivion - nothing beats that one hey Gryzor - btw anyone made a map? Still can't finish that even with infinite lives)


Rebelstar - CPCWiki


Now - I was wondering if anyone knows how to disassemble/pull apart the code somehow and make mods? i.e change maps slightly, add more droids, weapons etc etc...


Anyone have any idea if this is possible, where to start on a venture such as this???


or would I need the source code?

Well, I'd learn Z80 to start with 

Looks like it's tile based, so shouldn't be too difficult to alter once you've isolated the main game engine.

WinApe is perfect for this - it has a built in disassembler which can label routines for you.

if you want to edit the maps, look in the memory dump window in winape.
find something that looks like data... poke some values, restart the level or scroll around.
see if things change. if they do, work out what each value can mean.

perhaps you can work out the way the map is stored like this?

@redbox: Z80 - no worries  . Winape - yeah right - I hadn't even thought about that... you can disassemble during run-time. I'll have a look.


@arnoldmenu: Winape again, yep. Got it. I'll start there...


cheers guys.

A Like for the Into Oblivion reference Haven't finished it either, impossible without devoting an insane amount of time and mapping it myself...
