You might find this worth reading.

Ah, ok. I figured it out. Thanks guys.

That's me up there; I forgot to sign-in.

I'm not sure exactly how to describe this but here goes. I'm working on translating a game (well, it's already translated, I'm just adding the final touches on the "hacking" side) and there's an issue with a certain string of text. Now, the 1K of VROM that contains the number tiles (0-9) (...

I realize the NES doesn't have enough internal ram to support this, but what if you were to use a cartridge that had on-board ram? I'm not really familiar with the various types of cartridges, but someone mentioned that FF3j keeps a copy of the water tile in ram and alters the ram copy, and that got...

I couldn't find this any where in the documentation, so I figured I'd try here. Can anyone tell me what the "-$" part means in the below? node_0_0 .db node_0_1-$, node_1_1-$+1 node_0_1 .db node_0_2-$, node_1_2-$+1 node_1_1 .db node_2_2-$, node_3_2-$+1 node_0_2 .db node_0_3-$, node_1_3-$+1 ...

That's me above. Forgot to log-on.

I've encountered two games now that do this, but I thought it was impossible. The games are Dragonball Z 3 and Dragonball Z Gaiden. They use Mapper 16 and have 16 banks of PRG-ROM, but some data (title screen for one and some minor text for another) is stored in the area of the rom that *should* be ...

Just open the rom you wish to remove the header from in a hex editor (I use hex workshop and hte built-in hex editor in fceuxd) and delete the first 16 bytes ($10 in hexadecimal).

You'll also need the file huffman.asm from the source archive (see top of this post) to actually decode the text; it's all very hastily described in the README. Thanks for uploading that. I've always thought huffman compression was a bit too difficult for the 6502 to accomplish, but I guess its not...

[quote="SnowBro"I have made a number of tools to create levels, encode text, assemble game logic scripts etc., but it takes some effort to package it and document it properly, so I'll hold off releasing it until someone asks. [/quote] I'm rather interested in the tools for encoding text, i...

Division is quite a bit different than Multiplication when it comes to writing a routine to do that, at least in my experience anyway. This site should be helpful in learning/refreshing you're memory on the workings of binary division: http://courses.cs.vt.edu/~cs1104/BuildingBlocks/divide.010.html ...
