I was about to shake my fist in outrage until I realized that the original 2D version is included as well as the 3D revamp. Thank God, b/c the 3D version just doesn't look very CV to me. If you have time, look for gameplay videos of Rondo of Blood on youtube. I just might buy a PSP to play this. Assuming they don't port it to other systems, I probably will.

Belmont: It's debatable whether "improved localization" is better, and furthermore, I'm not quite sure I see your point as to why it's smart to "give the SONY product better everything". What are you trying to say here?

Zidane: Of course it is. And if they change what CV looks like certainly people are going to notice and react, either negative or positive.

Unless there have been leaps and bounds in the quality of DS emulation, I do believe you will have to fly blind. I wouldn't even try hacking a DS game without a decent disassembler or decompiler. IDA Pro seems to work fairly well, though I haven't done much to work on the roms I'm insterested in.

Posted on 02-04-07 09:40 AM, in 74LS139 vs MAD-1.... encoded? Link
I've never messed around with stuff like this (due to ignorance mostly), but I looked up the specs on these a bit and it one of them said it was capable of addressing more than one chip. Does this mean that they are capable of a "bank switch" of some sort? Or does that mean that it supports multiple maskroms which are treated as one ROM. I'm just curious b/c it would be interesting if you could find some ways to get around that 64 megabit limitation on game size. Just to say you can do it and all. I know the SA-1 has bankswitching, but I'm not sure if it is bank switching as I understand it, (i.e. like with NES games where you swap in different rom data by using the mappers)

hehe... well it's not like I was lazy about it, if that's what you're trying to say. I even downloaded the source code to try to see what I was doing wrong. Now I feel like I should give it another shot .

My brother visited Boston last year, and he said that it's the only city he's been in that has signs at every street corner saying "If you see anything suspicious call the police immediately!!"

Sounds like a paranoid-as-fuck town and I'm not surprised.

If it's "just you" then yeah, that sucks. Anybody who feels socially inept (like me most of the time) is going to feel isolated and like there's nobody like them. I've had what I think is a less than average amount of friends in my days, and they come and go for various reasons. Divergence in interests, or attitudes, or moving away, etc. It sucks, but I just focus on the things that I like to do if I have no one to hang out with. I dunno, do you just not TALK to people or something? I was really shy and introverted as a young kid, probably until 5th grade. Still don't like talking to strangers much at all.

You just have to make the best of it, I guess.

Okay... I got impatient and started playing this game on emulator. What can I say, I'm weak. I can definitely say I've found 4 different routes already and Magic Engine only has 4 save state keys... oy have to save carefully. It's also significantly easier after playing Dracula X for SNES.

Posted on 02-07-07 04:17 AM, in Having a problem changing some palettes in all games using snes palette Link
Well... let's see. I would look up what the format of the savestate file you are using is. For example, if it's ZSNES, find the file format for .zst or .zs0 files, etc. Look in the documentation for where the "CGRAM" is stored in the savestate. (If you're using Snes9X, you will have to decompress the savestate first. To do this, change the file extension to .zip or .rar, or maybe .gz, I can't remember exactly, and decompress the file.) Open up the savestate and modify the CGRAM bytes in a hex editor.

CGRAM is 512 bytes long, so that means it has 256 separate color entries, each being 16bits long. Using Virtual SNES, see if the palette you have changed is the one you were looking for. This is kind of a process of trial and error, but you're going to want to look in the second half of the CGRAM bytes, b/c the first half is for backgrounds, and the second half of CGRAM is for sprites (i.e. X's armor is a sprite so it will be in that section.) All sprites are 4bpp (16 colors), so the length of the palette is going to be 16 colors * 2 bytes which equals 32 bytes long. Each palette is separate from one another. So bytes $100 through $11F of CGRAM would be the first sprite palette, $120 through $13F would be the second, and so on...

I'm pretty sure VSNES will tell you in the section where you view sprites which palettes X and his various body parts are using. So if it says X's armor is using palette 0, you would edit $100 through $11F and voila, the colors should change when you reload the state after editing it.

Now for how to edit the actual palette in the rom. Once you have located the palette in the savestate and know for a fact what the 32 bytes designating it look like, you begin a search for that same string of 32 bytes in the ROM itself. The problem is, that the first color of any palette is always ignored, b/c it's considered to be transparent anyways. So you may want to search for the last 30 bytes of the palette instead, it might be easier.

If that doesn't work, the palette may be compressed, though I don't think it's all that common for that to happen. Or it might not be compressed, just stored in a weird format that makes the code that loads it a little more reusable. I can't say there's a general surefire method to do anything in ROM hacking, but this method might work for you.

Posted on 02-07-07 06:58 AM, in Does Anybody Other Then Me Bother With PSX Emulation? Link
Summary of Chrono Trigger on PSX:

1.Start game...
2.Crono begins moving around, you hit Triangle to open the main menu.
3.Load time...
4.You get done with that, exit your house
5.Load time...
6.You hit the menu button just b/c you can't believe it took 4 seconds to load the menu the first time. SNES CT was never this slow, not even close.
7.Load time...
8.You decide to play through for a bit, maybe it won't be so bad.
9.You eventually arrive in 600AD to find that the music so wonderfully rendered for CT on the SNES sounds hollow and cheap on the PSX port.
10.You turn your Playstation off and go play on an SNES emulator, b/c some jackass stole your CT cartridge while you were in college.

True story...

Your posts are starting to irritate me, SamuraiX. What do you want exactly? Tarale is being very informative and patient with you, just trying to see if you're depressed, and if you are, she's just trying to help. But every one of your posts in response to hers is an open ended question that is comes off as being standoffish.

You don't sound happy to me, and you're being very dodgy about it. So either you're in denial, or you just came in for a philosophical chat. But I can't stand to see you patronize someone like this. At least, that's what it looks like to me. You sound bitter at other people b/c they aren't like you. You seem to have something against people being "normal" which is meaningless b/c everyone is different, one way or another.

Asking if being sad all the time is bad is like asking "is it bad if I feel a burning pain in my chest all the time?" So yeah, being sad all the time would indicate that something is wrong, just like burning pain in your chest would indicate you are about to seize up from a heart attack. Obviously these are different degrees of severity, but still... I'd say it's okay to indulge in melancholy thoughts once in a while for entertainment (e.g. reading The Scarlet Letter), but actually being sad is not fun at all. Being truly sad is like being in pain.

And finally, you ask if chronic normality is a disease. no. Disease is by definition a state of being divergent from normality.

I did answer your question, but you weren't paying attention. Disease and normality are mutually exclusive. Chronic normality would therefore not be a disease. And I didn't question your answer, I questioned your question. B/c that's all you've been doing is asking combative questions like you know what you're talking about.

And you're spouting nonsense. Pain is your body's way of letting you know something is wrong. Yes, it's possible for nerves to misfire, or not fire at all. People who don't feel pain generally die of papercuts and the like; this is well known. I think that should be enough to convince you. As of now you are speaking in riddles and I don't really care to continue discussing your hypotheticals.

Does having modern games crash on me count? This happens far too often than I'd like .

Shadow of the Colossus, Scurge, Portrait of Ruin, ... Wind Waker, Metroid Prime, Mario & Luigi PiT, pretty much any game I've played in the past 3 years has crashed on me. What ever happened to beta testing?

Anyways, the only major glitch I'm known to have discovered is the Green Gate Glitch for Super Metroid. link.

Posted on 02-09-07 11:26 AM, in I need a program that does something, but I don't know what. Link
I suppose you have a program, and feed it a picture it has to create... then you give it a directory of pictures it can choose from.

You then take the average color value of each picture in the directory by, i dunno, averaging the color of all the pixels each picture. i.e. if it's 64 x 64 pixels, it might have an average value of 0x334455 or something.

Then you take the picture you want it to piece together, and seperate it into a grid based on how many pictures you have in the directory to choose from. i.e. if you have 83 pictures you could select to have a 9x9 grid or a 10x8 grid. Then you'd average the pixel values over those regions.

Finally, you'd match average pixel value regions in the target picture with pixel values of the pictures in the directory.

I mean, this is pretty rudimentary, but it might work.

lack of experience? ignorance? need we go on?

p.s. btw programs don't need a main( ) if they are windows apps. They use winmain( ). And if they use MFC the winmain( ) is even hidden. I had that pain the ass the other day trying to figure out the source of some program I downloaded.

quantum computers are not necessarily faster, it's just that if they become scalable, they will be able to crack encryption in hours and days rather than millenia and end of the worlds. Basically, you can employ some probablistic algorithms to do things normal computers can't dream of doing. One common example application is to factor an integer into its primes. IIRC, the best digital algorithm would yield N2 time, where N is the number of digits of the number. The best quantum algorithm would yield sqrt(N) time, which is better than linear.
