I even remember people saying it was "impossible" years ago. Nothing is impossible of course.
And probably doesn't help that NES is a bit trickier to expand the ROM of. Not that hard, just not as straightforward as it can be with SNES games as far I can tell. ____________________ AIM: gamefreak1337, MSN: Emil_sim@spray.se, XMPP: ailure@xmpp.kafuka.org

The game uses a sort of 6 in 1 compression scheme. For any given block of data you can have these mixed in:
raw data 1 byte rle 2 byte rle 1 byte rle + increment lz lz bit-reversed lz reverse read You can also set a flag to increase the size of the run. The compression was the main reason I started working on this. Writing a decompressor was straight forward. The compressor I have usually saves a few bytes over the original data, but its slow. This game is pretty strapped for space and I think it's already hit the upper limit for the MMC3. I think a mapper hack to the MMC5 is the only way to go. The program is written in VB6 + WinAPI. |

How was it figured out? That's quite interesting nevertheless.
Hacking it into MMC5 sounds like a good idea if space is truly that limited. Then again the space is only a problem if the hack winds up being bigger than the original idea, as long the old level data is used like free space. ____________________ AIM: gamefreak1337, MSN: Emil_sim@spray.se, XMPP: ailure@xmpp.kafuka.org

Hello there!

That's interesting how you well you imitated the snow graphic from Yoshi's Island.
I like it. |

It's hard to get snow right. I guess if you replace that grey with something better looking shade, or dither it up a little, it probably would look good. ____________________ AIM: gamefreak1337, MSN: Emil_sim@spray.se, XMPP: ailure@xmpp.kafuka.org

I have two screens:
I'm still working on ripping graphics(especially from 16-bit games). |

That Kid Icarus hack looks good, how much more you have to go until it's finished? ____________________ My Linktree |

Oh okay I got ya's, damn I wish there was there was a full blown editor for this game. Kid Icarus is one of my old favorite NES games, I hope to see more pics soon. ^^; ____________________ My Linktree |

Most earlier NES games had quite a fondness for strong saturated colors, including Kid Icarus. ____________________ AIM: gamefreak1337, MSN: Emil_sim@spray.se, XMPP: ailure@xmpp.kafuka.org

Oddly now I look at it again, it oddly reminds me about how Nesticle used insanely saturated colors for everything. ____________________ AIM: gamefreak1337, MSN: Emil_sim@spray.se, XMPP: ailure@xmpp.kafuka.org

Posted by The-doggy Damn! Pretty nice, interested in helping someone out sometime! I'm hiring someone who can design nice graphics. Anyway, I should take this hack for a spin when completed. |

For some reason, I started working on a Excitebike editor, named Biker...
The game is very simple, 1 PRG bank and 1 CHR bank. It's a shame there aren't more tracks, and by adding a bank and using the 8000-BFFF memory range, we could insert some serious truckload of tracks... |
