Ripping C64 sprites - maps - KillaWatt Port to Amiga

invent · 15 August 2022, 12:39

Hi Everyone,

I plan on porting a C64 game to the Amiga, "KillaWatt"

I am in need of some help in capturing/ripping C64 maps and sprites. I have sourced two maps online, and both seem slightly different, with pixel inconsistencies.

Would anyone who might know how to rip maps for C64 please consider ripping the maps for this game. Very happy to add credits in game for any assistance

Here is a quick video of the Scorpion Engine.

Everytime I try to capture it manually in emulation eg Vice, Virtual64 or C64 forever, pixels get stretched when game scrolls. See screenshot.

I plan to make it work for all Amigas OCS upwards.

No need to create more than one map for this game. All maps are the same except colour and enemies. Game says it has five levels, I went up to 7 using Vice emulator and sprite collision off… interesting.

I think I’ll remake the first level and actually create 4 over different levels.

I am curious about your remake. The original game is very simplistic and cute, so the Amiga port should keep the same style. But upgraded Amiga like graphics is very welcome. I have seen your initial attempts in Patreon and it looks promising.

Thanks Predseda, For the moment I have reduced the palette to 16 colours so all OCS machines can play it.

From the game engine though I will build upon it into a new game with more variety in game mechanics and ideas/themes.

All of the tiles are drawn now though or the first level.

Did you construct the maps by hand or did you found someone who ripped them out ?
Cool project.

Hi LeCaravage, Thankyou, I constructed them using Vice Emulator. Now that I know all maps are simply recoloured level one maps, it will be easy to make the others.

No ripping involved.

This is the same for all the enemies, all captured manually (think I have every sprite now)
