So the other day I was talking with my Programming teacher and an idea came in my mind.
"Let's load image in game from the game's code."
So the idea follows - We take the image's data and transform it into HEX code. Then we write an array of each hex value for the image, then we load the image from Array into the game and we have our sprite.

Wait, so we load an image and then save the image to the game again?

It sounds like a cool idea, though I'm afraid I am still lost on the reason for doing this. Would you mind elaborating a bit?

I just came up with such idea, well some engines do not compress images etc. and hackers can easier MOD the game. This way they don't, AND if they were to edit your code, they would have to recompile it, and you can add uncompleted code there, which at first does nothing but serves as the defense system of the game, and we can punish the players for hacking

@ 1st post:  Yep. I do believe that is the way you do it.

@ Last post: I see it more as a way for hiding information / decluttering the user experience rather than anti-hack, but okay. (Maybe anti-hack for the inexperienced, though...) Closest I can think of to anti-hacking is a server+client approach that requires an internet connection. Any sensitive data (e.g. Save data) could stay on the server. (That being the server isn't on the player's machine, but the client connects to it.) But of course... if one is going to build a server+client thing... then there's the possible issue of DDOS and such... so, eh. It's never that simple.

Anyway... the client should only send input data like mouse clicks and keyboard presses... and receive image data/audio data.... in best case circumstances... but that's probably a lot of data, though... (graphics/audio), so probably not recommended. But if it was done... I recommend a small resolution (e.g. 240x160=0x9600 pixels)that could possibly be zoomed in to full screen. (So less data is sent across the internet than otherwise.) As for music... I'd say just send the audio file over to the user... As people will probably document it anyway. And less internet traffic=better.)
@My idea:  I can see its potential for a 4-player game, maybe... but a large MMO, probably not. - In that case, image caching would be the way to go, most likely.

It's more of like a message, don't mess with this engine, I don't like what you're doing, I.E. Easter egg.

Wait, so you want the potential for a hacking community dedicated to hacking the game to make it harder to hack the game? :o

Or do you mean in general, like as a security feature for other games or sites?

A message? Might as well spell out to them.... that you are the copyright holder/etc.

But anyway... in the situation where a program is not open-sourced... data/images that are stored outside the program can still be checked against a checksum/signature type thing... if they need not be edited by a user. If editing was the main concern and not necessarily exposure/etc. But that's more me just speaking of an alternative. (That is definitely not foolproof. But then again, neither method is.)

Now I wonder if it is possible to encrypt a file using certain built-in techniques... and make it so one's own program can decrypt it... but only into RAM. (Without actually grabbing any encryption related code yourself.)

Okay pretty nice.
But what kind of format are you going to use? I guess that would be the first step in this problem.

Now that I think about it, you might only need to specify a width for the image and then simply just load RGB values, which makes an extremely easy format.

javi3: Atrius, por que no sigues con el editor de golden sun?
June 20, 2017, 10:52:48 AM
Fox: It feels like the safest bet is to do Atrius's repointering system, and have something that organizes the tables done a bit separate... er... Well, it's something to think about.
June 20, 2017, 08:53:41 AM
Fox: HOWEVER... I can see other problems that might cause..... (Even with just the pointer in the MFT)  Meh. It's like you actually need a program to apply patches to do it appropriately.
June 20, 2017, 08:46:38 AM
Fox: ... So... What am I thinking? You ask? That the patches the point data after MFT, should have had pointers in the MFT themselves.... In that case, I can see a possibility of everything working smoothly even if space is needed to the very end of the ROM.
June 20, 2017, 08:37:22 AM
Fox: It's basically that everthink from the point of  editing, to the closest free space to the last entry's address would get repointed forward/backwards depending on space needed... and if space is mapped after patches are added, then that could mean the patches are also repointed. (:o)
June 20, 2017, 08:29:03 AM
Fox: Well, I mean if I map the space out the same way Atrius did it.
June 20, 2017, 08:26:41 AM
Fox: I have a hunch... when I add Map Palette editing the way I'm thinking about... it will cause all patches that repoint to after the MFT to break.... Especially if Atrius's editor wasn't used beforehand. Etc.
June 20, 2017, 07:27:17 AM
Fox: Hmmm... Let's see... regardless of method, I think I still do want to take some of Atrius's Space Manager code... Hmm.....

Fox: say*
June 20, 2017, 07:07:19 AM
Fox: I'd go so far as to see.. even if you are trying to be accurate, there could still be inaccuracies... However, that one was just an example where it was clearly intentional.
June 20, 2017, 07:04:03 AM
Fox: Like*
June 20, 2017, 07:03:55 AM
Fox: Let that one time where they tried to clip a guy out... To put it as short and vague as possible.
June 20, 2017, 06:58:52 AM
Fox: But in case you do watch it... I do know the story on TV that they tell... is not always accurate to what actually happened... (From what one can find out from the feed.) ... but usually the fansites will let you know about that.
June 20, 2017, 06:37:54 AM
Fox: Depends, as each person may have a different opinion... (I'm thinking you might find it like other "reality" shows..)  ... I'm not really into Survivor at current.... I also question if it was something about Julie Chen that made it a little more interesting.... .being the an iconic host that she is.. Weird.
June 19, 2017, 11:57:31 PM
Dendrophiliafish_the_skull_licker_xxXXDx101XyeahbabyyeahxxXX: Honest opinion but is it any good or is it just like all other "reality" television?
June 19, 2017, 11:57:00 PM
Dendrophiliafish_the_skull_licker_xxXXDx101XyeahbabyyeahxxXX: I have a friend who is obsessed with that show and Survivor and he wants me to watch with him.
June 19, 2017, 07:47:18 PM
Fox: So.. as soon as I saw the cast of BB19, I wanted to try to pick my favs on first impression... And I'm curious about these: Elena Davies (Female pick, maybe.) and Kevin Schlehuber (Male pick, maybe. - He's the oldest.) ... whether they even get close to the end or not... I have no idea. Would have to watch them play the game.
June 19, 2017, 05:46:42 PM
Dendrophiliafish_the_skull_licker_xxXXDx101XyeahbabyyeahxxXX: Lol, well I had Squirtle for a while but I'm usually better known for Yoshi. I hope! :o
