If you try to walk from above, there are 2 squares in the choke-point that will stop you. If you try to fly, most of the checkpoints are located as a square on the mountains, so you cannot land before the scene triggers.

It only matters when you land because those checkpoints won't trigger once you're on the ground. The scene doesn't trigger because you did it to fast, same principle as when you want to skip steps in the world map in order to avoid monsters. You can hold the button and land w/o relying on been on time.

Regarding the event flags, it would seem that the only thing that prevents it is not been able to enter the town (because it would disappear when you approach it). There are some other events there (Mid & Cid falling into the catapult & the boss fight) that will not trigger again.

I have found another little issue only happening in the RPGe translation at the very end of the credits.
There is a scene where all characters perform an attack and after that is displayed the list of commands and abilities learned by every character.
Is interesting, that no command or ability with more than 8 characters is displayed in that list. That is because the original japanese names are no longer than 8 bytes, but some of the RPGe names can be as long as 24 bytes.

The routine which fill the buffer to display the names first reads and store the name in the buffer and after that fill the remaing buffer with blanks until the '8' bytes are filled.
The problem is, if more than 8 bytes have been stored, the buffer is going to be filled by blanks in every position from the last byte to 255 (when an overflow happens) and after that from 0 to 8. In the process, every stored byte from 0 to 8 is blanked.

You can check it. In example "MgcSwrdL4" is never displayed as adding "L4" to "MgcSwrd" sets 9 bytes.
Some other abilities as "Learning spells" or "Equip swords" face the same behavior.

To fix that, the easier way is to stop the blanks fill in 0x18 and not in 0x08. That is done by editing:
Code: [Select]
C1/31FE 08 => 18
That is not enough because the texts doesn't fit as they are very shifted to the right side of the screen. To move the texts to the left the byte which marks the tile-X to display these lines is stored at:
Code: [Select]
D0/E164 15 => 11

I never encounter that bug because I don't use RPGe's translation (was it DeJap's the other translation?). I saw it like a year ago in a speedrun where someone used I believe Chemist as Krile & they seemed to be familiar with it.

On other news, it seems that there's still the infinite item steal bug in FFVA. The steps to reproduce them are slightly different, but the setup is the same (you need Throw and Steal). It was discovered by the Japanese community (no idea who did it) and brought into me by neo_omegon. I haven't played much with it and don't really understand why it works, but it does.

You can read about it here. I'll try (eventually) to look at it and see why it works. There's also a second bug (also explained there) that lets you steal a different item, I don't get it quite why it steals such item even if claims it uses the enemy's special attack ID (which doesn't seem to me):

Yes, the DeJap translation doesn't have ability names longer than 8 bytes (at least in that scene) so every ability is correctly displayed.
On the other hand the "MgcSwrdLX" command text still disappears.

I haven't tried this one yet, but wanted to mention it in case someone knows about it.

Magic usually has certain percentage to connect, unless the "Always Hit" flag is on. There's Remora's magic Latch On which has a 100% of hitting (which doesn't immediately translate to always hit). I find it funny that is not 99% nor 128 (always hit). The catch here is that in a Speedrun, you use Remora in order to paralyze Titan & while he's level 1 I've heard you can miss the attack.


Code: [Select]
6.2.2) HIT DETERMINATION FOR MAGICAL ATTACKS
Hit% = Spell Hit% + Attacker Level - Target Level
Evade% = Target Magic Evade%
...
Let N1 = (0..99) 
    If N1 >= Hit%, the attack misses;  do not follow any more steps.
Let N2 = (0..99) 
    If N2 < Evade%, the attack misses;  do not follow any more steps.

Titan has level 1 with no magic evade (and obviously can be affected by paralyze). I think in a speedrun you should be around level 13 or so... Unless the Hit% drops to 99 (no 3 digit number) or N1 can get to 100, I can't see why it would fail at all.


Note: Faen Fantom & Chocobo Kick also have a 100% instead of always hit.

If Titan has Shell, then Hit% = Hit% / 2 (6.3.6)
Also if somehow you manage to summon it as multi-target (it should not be possible ...) you get same effect (for hit%) (6.3.3)

P.S. Out of curiosity, why will you use Paralyze on Heavy enemy?

Since is a speedrun strategy, you paralyze Titan with Latch On so that in the moment he dies, he can't use his death script (Earth Shaker). Titan doesn't start with Shell and since it's a speedrun, you don't inflict it to begin with (hence why I posted it under the bugs topic).

However, looking at what you mention (Heavy status), that might be the reason it "doesn't work". Is not that it fails (AFAIK) but rather that the duration of the status gets reduced from 240 to 30.
Code: [Select]
If the Target is Heavy type, Status Duration = 30;  do not follow any more steps.

Yeah that was my point, Duration = 30 (vs heavy) which is VERY short. I tried before to use Stop on Omega ... it was terrible - you need 2 chars dedicated to Stop, you need haste, battle speed reduced to slowest speed (in menu) ... and still it was very, very hard to keep him in Stop :D
I like to kill super-bosses like Omega in non standard way :D

P.S How about Float to counter Earth Shaker?

You would need to control/confuse a Gaelicat for that, which takes time to prepare for it. The other strat is to jump with the Dragoon's ability so that you evade it that way (conceal works too, but you need lots of ABP before you learn it, so not viable). Can't remember if there's a setting that allows you to withstand the damage with those levels, but you usually want the ABP for jobs anyways.

I'll try to talk to the speedrunner (EiriasValar) to see what really happened. I had the impression that the attacked missed, but looking at the data it probably was that the effect just ran too fast to work.


Edit: I can't remember if I'd mentioned or not, but the infinite item steal glitch does work for the GBA. Since today I have the day off, I want to look at it. For the steps, they are mentioned here:
http://tasvideos.org/forum/viewtopic.php?p=425968#425968

Edit 2: Here's the video EiriasValar made, around 25s is where the magic misses (no animation):

Here's one to add, how about the fact that you can land the Airship or the Hiryuu on the entrance to Guido's Cave? If you do so, it will become permanently inaccessible. In the case of the Airship, it will become impossible to finish the game. Full details here.

Not only the airship


BTW, it's already mentioned in the wiki page

OK. I was fishing a bit; it just kind of annoys me that no one's made a patch to say "you can't land anything on the entrance to Guido's Cave". And I don't know how to edit that myself.

Well... Samurai Goroh, before me, and a lot of people before us tried to understand how the locations and world map work but there is very little information about the topic.

You can start reading the wiki and continue the research from the point where it is now.

Do you mean editing the wiki? It is quite easy, just click on the Edit link and change the code as desired.

No, I mean there has to be some bit, or combination of bits, somewhere in the ROM that is/are wrongly configured, allowing the player to land stuff on Guido's Cave. The problem, as noisecross points out, is that no one knows where that is yet. That's what bugs me right now.

I can help out to some degree, if it means finding the problem faster. I see that noisecross appears to have narrowed things down a tad.
