Topic: My mapping projects

[dark_lord_zagato@yahoo.co]

I finished Magic Knight Rayearth and sent in the maps. There was a bug in the emulator that caused some backgrounds to not display right, usually water backgrounds. It wouldn't screw the whole map, just the bottom right corner. The good news is that i was able to fix most of these maps by making transparency layers and fixing the water separately. The bad news is the Crimson Underpass still looks pretty bad and there's nothing I can do about it. The ground itself is mangled in the corner and it's not something where I can just copy the good part and smooth it over.

I'll have to leave it for now. Hopefully i'll be able to do something about it eventually.

I'm going to share some of my hacking notes for Bart's Nightmare on SNES.


In the Temple of Maggie, the top part of the screen (with the Maggie statues) will scroll at a different pace than the bottom of the screen where all the stepping stones are. This makes it impossible to align the Maggie statues with the stepping stones that would normally have a pacifier fly across them. In fact, the stepping stone walkway is a lot longer than the Maggie statue background at the top of the screen.

PAR code 7E0915?? was used to get the rest of what I needed from the top half of the screen. It only works when Bart is in the air, but paired with the code to make falling non-fatal this is not a problem. If the value is 01 the screen will scroll to the left. Set the value to 20 or higher to make the screen scroll to the right. The lava pool extends forever in both directions.

PAR code 7E00B200 makes falling non-fatal. If you jump on a flaming block and go into the lava you can just jump right back out. You can even out run the pacifiers by mashing right on the d-pad.

PAR codes 7E0E389E and 7E0E39E1 freeze the background animation.

The stepping stones in my maps represent the original position of these stones. This is the way the path will look before you take even one step. To do this, I went into BizHawk's hex editor and froze everything from 0E3B-0ECB in the WRAM.

36 stepping stones in a row multiplied by 4 rows = 144 total stepping stones in the Temple of Maggie.

Now that GBC Crystalis is done i've decided to take up Jon's request and start on the NES Crystalis maps.

Now that NES Crystalis is done I have to share some of the weird stuff I found with that walk through walls code. First of all, I think the game has a bunch of premade "screens" that it uses to build dungeons with. It doesn't lay down 16x16 tiles like most games do. Instead, dungeons seem to be built with 256x240 tiles. In a way, it kind of reminds me of the labyrinths from the original Legend of Zelda. This causes things (like doors and walls) to loop around in places that are normally off camera. I'll post unedited versions of Oasis Cave (from Goa Fortress) and the Floating Tower. The loop around effect is especially visible in the Floating Tower.



I also found a glitch door inside the wall of the armor shop in Portoa. I recorded a video of it and posted it to my Youtube account.

Now to share some codes.

1FF1:04 freezes the background animation, although some places require 1FF1:20 instead.

0051:03 is the most useful code I found. I originally made it to get the HUD off the screen, but then I noticed that it also somehow fixes the nametable viewer in BizHawk, which wasn't working right at first.
