Maps ripped from the ROM using a PHP script. So clever it hurts.



Someone should ask the guy for permission to host the maps here. Missing enemies, though...

I can't help but be amazed every time someone manages to rip maps through programming alone. All that stuff about tiles, bit masks, address blocks, map compression makes my head spin Shocked



I just find it a bit disappointing when the ripper stops after that instead of polishing the map by adding the more important sprites to get a better-looking finished product. You just can't get everything through coding alone most of the time.

It looks like he's still working on it. There are ID numbers on the maps where the enemy sprites go, for example.



The technical details are a bit heavy, but so long as you can learn a bit of assembly code (and Z80 is pretty basic) unravelling the compression can be pretty easy, just time-consuming. I find it more fun just to map the "old-fashioned" way a lot of the time, although being able to hack can help a lot.
