One more thing, i geuss you need some decompressor for it?, and any progs i downloaded from that other site, aren't good at all, and why is ESEII editor in some frickin spanish/portugese lang isn't their an english version.
Cheers
geez.
i dont know how often i'll have to repeat that, but if you want to rip a bg fast and easy, this is what you have to do:
1.) make one or more screenshots of the bg you want to use while the game is running on an emulator.
2.) use your favorite graphics editing program (i recommend paint shop pro) to merge these screenshots into one background picture.
decrease colour depth to 16, edit the palette so that colour #1 isnt used in the picture (its the transparency colour on snes), then increase colour depth to 256.
3.) save as version 5 256 colour pcx file.
4.) convert the file with nevikstis pcx2snes (get it here http://snescentral.edgeemu.com/Development/dev_kit/SNES-DevKit.tar.gz ) using the following command line options: pcx2snes -screen -c16 -s8 nameofpicture
this will give you three files, namely palette, tiles and tilemap.
5.) rename these to the lunar magic equivalents for exgfx and import them into your hack.
for sprites or other tilesets that dont have a tilemap, youd do it the same way, but
force pcx2snes to convert all tiles without rearranging the tileset and outputting a tilemap, like so: pcx2snes -n -c16 -s8 nameofpicture
you will end up with a tileset thats an exact representation of your pcx file, plus the palette.
forget stupid stuff like importing bitmaps in yy-chr or tlp.
when importing genesis graphics that way, youd also have to manually make up a new palette and tilemap, wich is a total waste of time and the outcome might not even be 100% accurate.

Oh, yeah, that's totally it. SEGA, back in 1992, knew people would try to steal their graphics for use in crappy SMW hacks 10+ years later, so they wanted to make it as tough as possible. Shame on them!
(Seriously, though, no. Large ROM chips were pretty expensive back then, so game designers had to use compression in order to fit everything into a smaller space. It's still used to this day, even moreso now that CPUs are fast enough to decompress data without a noticeable impact on gameplay. The GBA even has decompression routines built into its BIOS in order to speed things up.) |

He'd like to put the graphics from a level in a Sonic game into SMW. Ignore the stuff I said in my last reply. Unfortunalty, this isn't as easy as editing a screenshot. You will have to familiarize yourself with Sonic's compression for the most ease at this.... Or look at dumped RAM. Otherwize, it requires expert use of Lunar Magic, Tile Layer Pro, and Photoshop.

"How the hell dp i rip a BG or FG from Sonic2 (Sega Gens) not SMS.
Ok i did convert the rom to .bin, but what utils do i need to extract the gfx or rip. Hmm maybe i need to take a screen shot and make it into an exgfx file?.
Thanks in advance"
What exactly are you trying to do here? Please, give me an exact outline of why you want these graphics and what you intend to do with them. |

Thanks guys!!.  I still want to know though, i'm trying to use an FG in Mario World, that i took from a screenshot of a Sega game called "Wonder boy: in monster world. Has nice FG gfx. And the rom is allready a .BIN, phew! saves me havin to convert.
I've tried copying and pasting some of the screenshot into Tile layer pro. Then the hard part i'm finding ughh!  , is getting the FG colour palette right for using in SMW. Any help with this i greatly appreciate!.
BTW, http://www.shacnet.com, umm when will it be avail then?.

If your ROM's in binary, you're set.
If not, then you need to convert it from .smd to .bin with one of the programs mentioned above.
It's still icky in TLP though. You open the binary with a program called "sonik sprite." for super-ease is you just want images. That can be found on http://sonicology.fateback.com/ |

Download ESE II from Esrael's site: http://www.projectnemesis.ibforums.com/esrael/ <--here. Click on the Ferramentas link and then eseii.zip. When you're in ESE II, use the ROM conversion tool and make it a .BIN file. I'll be more specific later if you want it, but I'm in a rush as it is and must go. I'll link a few people to this thread so maybe they can help too. |

 I never saw that... I spose I need to pay more attention to what I link. Oh well, it may help if he uses Mac...

Most of the background and sprite tiles are compressed. If anyone has the information you need, you'll find it at http://www.shacnet.com/. (Note: Site is not available at the moment.)

The Genesis roms (by default) have a sort of interleving done to them, which is done by the rom dumpers. You'll want to take a look at this and convert the rom over. Then you'll be able to edit the graphics as long as they aren't compressed. Hope that helps. |

Hi,
I'm wanting to know how it's possible for me to rip the FG gfx and enemy sprite gfx from the Sega Gens/megadrive Sonic series?. Cause when i've tried with YY-CHR or TLP, its there's nothing there except mess, and yes i do have it on the (Genesis/MSX) viewing.
Thx |
