New patch: Imp's Retort Bug fix
« on: May 11, 2015, 09:55:07 PM »
Hi! Wow, this is my fourth patch today! I've been keeping busy!

So, anyway, this patch fixes the second half of the Psycho Cyan Bug, the first half having already been addressed by Terii Senshi's patch. That patch, although sufficient to limit Cyan's caffeine intake, only fixes one, but not both, of the two bugs that combine to create the Psycho Cyan Bug. The bug Terii Senshi's patch overlooks prevents Cyan's Retort from being cleared if he tries to Retort while he is an Imp, thus allowing him to counterattack every attack against him until his next command input. This patch corrects that.

EDIT: Anyone who has applied Assassin's "Jump Megafix" patch will need to re-download this patch; as the replies explain, the old version causes a problem with the Jump Megafix. If you've previously applied my Zombie/Tapir patch, you'll need to re-download that, too.

EDIT 2: I've now included a patch for the Japanese version of the ROM.

EDIT 3: As of May 3, 2016, this patch no longer uses any free space.

EDIT 4: The new version causes a logical conflict with "Jump Megafix" which causes Jump to never deal any damage. I've now included compatibility patches to circumvent this problem.

EDIT 5: Found a pointer that needed updating and...updated it. It's the pointer to Umaro's "normal attack" procedure. Better download the new version or else your game will reset whenever Umaro attacks.

EDIT 6: GBA port added!

i believe this will cause an issue when combined with my Jump Megafix, which branches to C2/1633.  the likely problem is having an ally summon Palidor after Cyan/Gogo uses Retort (part 1) will cancel his retort when Cyan/Gogo lands.  a "CMP #$16 / BEQ skip_retort_clear (so F0 06)" at the beginning of your new code could work.  alternatively, moving the "JMP $6752" (plus a NOP) to C2/162F, and having your extra code end with RTS, would be 2 bytes smaller (not needing the command check, so 11 bytes free space vs. 13).

so not a physical patch conflict, but a logical one.

if you're not up to making your 34th .IPS file in two days, then this post will just stand here as a warning and guide for anyone who seeks to combine the two patches.  also, i hope to increase awareness of the Ides of March, and bolster the general public's traffic safety.

Even better, I can use a BNE instead, since the command ID for Fight is 0.

Doesn't that mean overwriting the code already at C2/162F? That clears the "No Critical" and "Ignore True Knight" bits. I'd prefer to leave them alone.

Oh, never mind, I see. I would move those bytes into the free space. Sure, that would work too, and it would probably save some time in the case you mentioned.

i'm on the fence with them being the same size now.

Any change to the functionality of the patch? I'd prefer to stick with the version that uses free space (less modified code).

Not that I know of, but I needed to clear up the free space to make room for Morph Mayhem, which now uses most of that same free space.

Ah, ok, thanks. If it's just that, making room for another patch, I'll keep using the old version.

Hoi.

I notice the regular patches in this update are changed, but the ones that are for compatibility with Jump Megafix are not. They are the same as before. Is this intended? Do the Jump Megafix compatible versions lack the error you fixed?

The Jump Megafix-compatible patches aren't standalone patches. All they do is adjust one JMP that needs adjusting because of the changes made by the main patch. They're meant to be applied alongside the main patch, after Jump Megafix has been applied.

Ohhh... Understood. Now, anyway. I'll need to update the omni-patch again. :eek: Thank you.
