I meant preventing things like that happening again in the future.
Especially don't want current active accounts being hacked for instance.

To my best understanding, the leak had nothing to do with the board software. Various people had access to the server at times and pulled copies of the DB, sometimes with the intention of archiving it while unilaterally declaring a replacement.

Hello, nice to meet you too.

Could you be a bit more specific about what you are intending to do? What do you mean by "address of hitting sprite" - an address that changes value when a sprite is hit, or perhaps one that holds the number of the sprite that the player is hitting? What have you tried to do so far? (英語では説明しにくいのなら、日本語でもどうぞ...）

So you are looking for a memory location that is used to store whether the player sprite has hit a wall and can't move?

It seems like the right process to do that would be something along the lines of:
1. Go near a corner, but make sure you can still move freely.
2. Reset cheat search. Press "ok".
3. Move the player character a bit without hitting a wall.
4. Start up cheat search without resetting. Set search type to "old value", compare type to "equal", data size to 8 bits, unsigned. Press "Search". The number of memory locations visible should have been reduced. Press "OK" to leave.

Repeat steps 3 and 4 a few times. This will get rid of many memory locations that change over time, but have nothing to do with the collision detection.

5. Now, start walking towards a wall. When you hit the wall, pause the emulator WITHOUT RELEASING THE MOVEMENT KEYS (so it freezes while still showing the walking animation), like so: 

    |
 ->o|    (o: player character, |: wall)
    |

6. Start up cheat search without resetting. Set search type to "old value", compare type to "not equal". Press "Search". This should have reduced the number of memory locations further. Leave with "OK".

This will reduce the memory locations you are seeing to the set of those that only became different once you started being prevented from walking into a wall. However, some of those might still be unrelated to collision detection - for instance, because they are for graphics or scrolling.

7. Press OK. Unpause the game. Walk around some more, and once again pause the emulator while "pressing against a wall", i.e. while holding down the movement key in a direction that is blocked.
8. Start up cheat search without resetting. Set search and compare type to "old value", "equal". Press "Search". This should further reduce the number of memory locations. Leave with "OK".

Repeat steps 7 and 8 a few times. This will restrict your selection to memory locations that are always in a certain state when you are colliding with a wall. This may be a problem if the collision detection stores details about the type of collision (so for instance it write "0" when there is no collision, "1" when there is a collision with a wall to the right, "2" when there is one with a wall below, ...); in that case, it may make sense to restrict yourself to only do 8 and 9 in a fixed direction, or use "specific value", "not equal" with 0.

I think that if you do the above steps right, at this point you will almost certainly be down to very few candidate memory locations (and can try setting them to a fixed value with a cheat manually to see what happens). If not, you can also walk away from the wall again and use cheat search once with "old value", "not equal" as steps 9 and 10.

If at any point your list of memory locations becomes empty, you
- either slipped up somewhere (getting even one step wrong, e.g. pausing one frame after having released the movement key that makes you walk into a wall in steps 5-8, will destroy the data and you will have to start anew), or
- the memory location is periodically erased and you caught it at the wrong time at least once, or
- the game does not actually have a fixed memory location in which it stores a "collision" flag (stack-based data passing?), or
- the collision flag is used for some other information while you are not colliding with a wall (so you lost the location in steps 3 and 4) already. Be creative.

I hope this was of help.

Oooh, pretty.

What's the deal with the spooky area to the left of the starting area? There is something that looks like an NPC in the skull room in its centre, but I couldn't figure out how to interact with it so far.

It is sort of sad how little of a life our French friend has.

I suppose this might be as good place as any to announce that if the forum ever gets shut down, it certainly will not be due to people desperately making posts that it must happen. In fact, every time I have thought so far that I would save myself a lot of time by just pulling the plug, I remembered that there are two or three unpleasant characters out there who seem to be positively grinding their teeth over the circumstance that it's still up every day, and so it continues to do good as far as I'm concerned.

Sorry to disappoint, but the "Xkeeper" you saw online was also Mega-Mario. He seems to have a large assortment of mostly weak passwords of old accounts, which suggests that he somehow got his hands on the hashes and presumably rainbowtabled them.

I figure it's most likely that somebody gave him a DB dump. Because a few somewhat recent accounts (like ShaneM) are also affected, I unfortunately can't rule out that there is still a live security hole somewhere that he's using (which might well not even be in the board code itself, but rather in any of the ridiculous number of 10-year vintage tools running on top of the DB).

You have a very predictable style in choosing names. We could probably train a very small neural net to recognise it.

Stop the sockpuppetry already. Another post by you from an account that's not id 3435 and you get a 1-week ban (to be extended if I spot any attempts to circumvent it by using additional ones).

I just banned the proxies I saw it using, hoping he'd get the hint without me having to waste more grey ink...

The only public releases of the 2.x series are the alpha version made available by Acmlm himself before the board was started, and the "higher version numbers" tree operated by the Kafuka folks. With the dearth of development manpower here, we never really had the confidence to deal with the fallout of people being able to scan the code for security holes directly.

They weren't intended for use with images. If you need more serious hiding, use (16 bytes collapsed: collapse) instead.

Why do IPs of guests and bots appear to normal members?
It could actually pose a small privacy risk to some people.

I imagine the rationale of whoever made the decision back in the day was along the lines of "see how many different places we have people browsing from"; of course, this has largely lost meaning since our geolocation database is extremely out of date. That being said, I'm not sure it's actually that major a privacy risk. It's not like you can gleam information beyond "this IP exists and visited that page"; Google, Facebook and co. get that data every time you visit something with a like button, Google ads or their hotlinkable web fonts.

Just a quick note - is the uploader definitely checked for malware or sort? My phone detects this board and blocks it (am on Virgin Media) so I have to use an Italian webproxy to get around it. I could use alternative DNS, though.

No, it's not; I suppose I would be happy to enable any layer of checking that can be run from the command line on a unixoid system without much effort. I wouldn't recommend downloading and executing binaries from it, just as I wouldn't with any other web source. Blocking it for that is silly for anyone but people who actually do just run random stuff off the internet; can't you contact your provider and have them disable whatever layer of idiot protection they think you need? (There's also a certain chance that they blocked it simply because of the presence of offending keyboards to do with ROMs and hacking. Do standard ROM download sites work on your phone?)

(I also know no other forum software that exposes any IPs to non-staff.)

I believe there were some flavours of imageboards out there that did...

Some people might feel a little unsafe having their IPs revealed to any plain person, I know of someone who's pretty conscious about their online privacy (in fact 2 or 3 people).
Explain why having (only) your IP revealed is a privacy risk. If it's just something you vaguely feel people shouldn't know, that's nothing more than cargo cult security...

(By the way, I just remembered: by far the largest example is how Wikipedia publicly identifies all anonymous edits by IP.)

Can I not leave you people alone for one week without you starting to flame around and bring in teenage drama from knockoff boards? As far as I can tell, this Staplebutter person you all seem awfully obsessed with has nothing to do with board2. Next time you feel compelled to post something about them, I would suggest stopping for a moment and considering the option of taking it elsewhere.

Sorry for the downtime earlier. The database seems to have crashed for inexplicable reason.

Regarding the board being a refuge for those banned elsewhere, I'm sure this problem will be sufficiently easy to resolve with some heavy-handed moderation...
