Posted on 12-05-05 03:50 PM, in Can Lunar Magic load other games with the x200 header? Link
I don't see why. It's stupid. The header is nigh-pointless for people who don't use console copiers, gets in the way of manual address and pointer calculation, is easy enough to detect and factor out of any hardcoded data calculations when programming software (just add a +header to your equation, where header is an int equal to either 0 or 512)...

The only people who should care about headers are the copier users, and unless someone's very new at using copiers, they should already know full-well how to add headers onto their games.

You can add me to 6502 and 65816. I'm hopefully going to be learning some R3000 at some point in the near future, and I'm in the market for a good C++ datastructures book...

Wrong.

Translhextion is big, clunky, buggy, can't search properly, has a dump format that makes me want to gouge my eyes out and eat brains, and is in general a piece of trash.

Windhex32, on the other hand, is small, sleek, lets you specify an external script dumper if you want, can load two tables at a time plus ascii, has built-in Unicode Japanese support and sports a ton of (fully functional) search options. Accept no substitutes!

Hex Workshop's great if you don't need any romhacking-specific functions. I did Cave Story in Hex Workshop. It doesn't have any wildcard search functions either, and that can be really aggravating sometimes.

For anything else though, WindHex32 all the way.

Agreed on principle, but Jason's a beginner and is excited that he's managed to change something in one of his favorite games. Let him have his moment in the spotlight! We can't all start out as superhackers making the next Zelda Outlands or Treasure of the Rudras translation

There's a difference between childish, immature pr0n hacks of low quality and legitimate sprite conversion jobs, and you know it. Jason did a fine job with the shyguy sprite, don't be such an arse about it

Because the SNES hardware is set up very, very differently from the NES. While such features would probably be possible, you'd probably just end up with some sort of generic VRAM viewer, as VRAM's set up differently in every game.

I don't think it's an actual MP3 decoder, I'm not sure that the 65c816 or SPC700 is fast enough for that. I think what he did was break the MP3 down into samples which he dynamically strung together, similar to what happened with Tales of Phantasia's opening song.

Posted on 01-29-06 12:54 PM, in "How do I" pointer help. Link
Say, is this Villgust? I remember playing a bunch of Villgust and getting stuck, just because there didn't seem to be anywhere else to go, and wondered if it was the fault of the translation.

Edit: Anyway, a pointer is simply a memory address (in an NES game) or a file/bank address (in an SNES game.) It tells the game where a particular piece of text begins. For example, in FF1 you'll see this:

See your face upon the
clean water. How dirty!
Come! Wash your face!


In this case, there'll be a pointer -probably- pointing to the capital S in "See." The reason the MadHacker's document talks about subtracting $10 is because of the iNES header - real NES games don't have this header, and it pushes all the addresses up sixteen bytes and makes your calculations nasty. Same with the $200-byte subtract rule on SNES games, except SNES headers are entirely removable with no real repurcussions.

The various formats that the MadHacker talks about revolve around how the game is programmed (as such, pointer tables don't necessarily work exactly the same way in every game), what the game's mapper is, and where the text ends up in memory. The 6502 also uses an endian mode that we're unused to. We're used to thinking in big-endian; that is, the biggest parts of a number come first. Most consoles think in little-endian; that is, the smallest byte are written first. This is the reason for the "byte swap" thing that you hear about when you're researching pointers.

So that's all they are - somewhat complicated (if only 'cuz you're not used to them) addresses that tell the game where to find a single given bit of its text. Hope that helps some.

d4s- Dunno what you've been doing, but I've been using code like this in my games for a very long time. Copy and pasted from my DMA Beginner's Doc:


org $02895F
JSL $1FE300 ;Here, we overwrite the old JSL that decompressed the font.
;Read the log to find out how this address was determined.
;If you don't have a 4-byte JSL or load to overwrite, then
;you'll need to overwrite more than one command and reproduce
;them in your DMA routine.

%org $1FE300 ;1FE300 is some blank space before our font. Yay.

LDA #$00 ;$4300 is the DMA control register. Unless you're writing directly to vram,
STA $4300 ;this should probably always be zero.

LDA #$80 ;$4301 is the destination register. The upper address is assumed to be $21,
STA $4301 ;so you're gonna have to figure out which of the $2100-$21FF registers you
;want to write to.

LDA #$00 ;...in our case, since we're writing to WRAM ($7E:0000-$7F:FFFF), we need to
STA $2181 ;use $2180. We store the address that $2180 goes to in $2181-$2183. I'm going
LDA #$11 ;to leave these blank, but they're in standard pointer format. Of note is that
STA $2182 ;bank $7E must be written as $00, and $7F must be written as $01.
LDA #$01 ;So, if you were writing to $7F:9320 you'd write $20, $93, $01 in that order
STA $2183 ;to $2181, $2182, and $2183 in that order.

LDA #$00 ;These registers contain the address your read starts from. Since we're dealing
STA $4302 ;with loroms, you need to remember how lorom addressing works, and you'll need
LDA #$F0 ;to convert the address of your new font ($FF000, right?) to a standard 24-bit
STA $4303 ;LoROM pointer. I'll leave these blank as well.
LDA #$1F ;You should be able to fill them in yourself.
STA $4304

LDA #$00 ;$4305 and $4306 are the number of bytes you need to copy. Again, the order of
STA $4305 ;the bytes is the same as before -- the high byte of your address comes LAST.
LDA #$10 ;Notice that you can't exceed 64K in this. That's cuz of the bank boundaries.
STA $4306 ;Don't try to copy more than 32K if you're dealing with loroms, either.
;Note that since you're not doing -addresses-, counting here starts from $0,
;not $8000, like lorom addresses would.

LDA #$01 ;This register starts DMA! Note that there are 8 DMA channels that can be used
STA $420B ;if you want to do more than one DMA at a time (channels 0-7.) We're using
;Channel 0. If we wanted to use channel 1, we'd be writing to $431X instead of
;$430X. The same holds for the rest of the DMA channels.
;Note that writing a byte to $420B can start more than one channel at a time!
;Since we're writing #$01 to it (00000001 binary), we're starting channel 0.
;If we wrote #$02 (00000010 binary), we'd start channel 1.
;If we wrote #$03, we'd start channels 0 -and- 1!

RTL ;Kay, we're done!


And damn straight it works on the real thing. Been doing this for years. I think the first game I used this code in was Gundam Wing Endless Duel, back in june of '02 :p

Edit: I'm positive I've used the same code, or at least extremely similar derivatives, in at least Gundam Wing, Shin Megami Tensei 2, Kunio-tachi no Banka, G-Gundam, Rockman & Forte, Gunman's Proof, Super Robot Wars 3, King of Demons, Magical Pop'n, Jutei Senki, Cyborg 009, Madou Monogatari, and Hiouden. It's also used in Shiren, although that's not out yet (soon!), and I might have to employ it in Fire Emblem. I can also say for certain that I've completed Gundam Wing, Kunio, Rockman & Forte, Gunman's Proof, King of Demons, Magical Pop'n, and Madou Monogatari on my swcdx2 copier :p

I asked the question of former-emulator-coder MKendora in my IRC channel, and this was the response:


[MKendora] you can't go WRAM to WRAM.
[MKendora] you can go ROM to WRAM, as far as I know.
[MKendora] RAM's not exactly on the A bus.
[Lakmir] this is a major concern for me, because a lot of my translations rely on DMA from ROM to $2180
[MKendora] Someone's on crack there.
[Lakmir] I can always replace the code with MVN or a load/store loop, but I'd rather keep the DMA if possible.
[MKendora] The only thing you can't do it A-bus WRAM to B-bus WRAM.
[MKendora] or DMA to DMA registers.
[MKendora] lots of games use that, iirc.
[MKendora] (ROM to 2180)
[Nightcrawler] According to Anomie's docs, you CAN write to RAM via DMA
[Nightcrawler] http://romhacking.deadbeat-inc.com/docs/regs.txt
[MKendora] then you pretty much can.
[MKendora] anomie's seldom wrong.
[MKendora] neviksti is the authority on limits...
[MKendora] and he only said no WRAM to WRAM DMAs.


Simply put, I think d4s is wrong No offense, man!

Posted on 04-06-06 03:04 AM, in Compression broken, problems caused Link
Okay, so I've hit a bit of a problem. I'm working on this game whose text originally was compressed. I broke the compression, preferring to store my data decompressed in-rom.

The problem is that each of the compressed strings stored the decompressed size with the string, PASCAL style. Now, the game's still expecting those bytes to be at the beginning of my strings, and it really doesn't like it when those values aren't there - or when the values that are there are much bigger than it's used to handling. Here's some example code...

I'm sure you can see what the problem is. Those values control MVNs, and 0006 specifically causes a lot of loops. I've run a full-execution trace without squelching in geiger snes9x, and that BCC never fails to resolve with the new script in place. To compound on things, this code is used for other compression-related things as well, so breaking it to load an absolute doesn't work. (It did elsewhere, though.)

Any suggestions?
