SF1 Various Patches and Fixes

[Siel]

Standalone Patches
These patches can produce changes to the gameplay on their own.

Change EXP Cap per Action to 100
The game originally caps EXP gains at 48 in a single action/turn. This patch essentially removes that cap by raising it to 100.

WARNING: SPOILER!

Compatibility/other info:
EXP gain calculations are otherwise left untouched, so actually reaching 100 may be difficult.

No Stacking Healing EXP
The game originally adds up EXP via healing from each individual target, which can lead to very high gains for AURA users. This patch changes this so that only the highest EXP score among all targets is considered.

WARNING: SPOILER!

Compatibility/other info:
This patch has no known conflicts with the editor.

EXP from healing can still be modified via the editor.

Extra data is added at 0x1C3280.

Static Combat EXP
The game originally grants EXP based on damage dealt. This patch removes that relation and makes it simply grant 1/3 of the enemy's total EXP per attack.

WARNING: SPOILER!

Compatibility/other info:
The patch has no known conflicts with the editor.

EXP bonus for dealing the killing blow remains.

Muddle Enhancer 50%
66% version
75% version
Being under the MUDDLE status originally sets the chance to miss to 25%, except when attacking a target with high evasion, in which case it has no effect. These patches change MUDDLE's effect to additively increase chances of missing by 50/66/75%, including when attacking a target with high evasion.

WARNING: SPOILER!

Compatibility/other info:
This patch has no known conflicts with the editor.
This patch conflicts with the editor starting from v3.0.0.

Default chance to miss remains at 3%.

----------

SF1 Editor Supplementary Patches
These patches don't really do anything on their own and require further changes to be made through the editor.


Multiple Outfits Per Character
The editor allows editing and adding outfit items per character, but only the first outfit for each character can actually trigger in-game. This patch changes it so that outfits beyond the first ones also get checked. Priority when there are multiple valid outfits is decided by the inventory slot order.

WARNING: SPOILER!

Compatibility/other info:
Saving in the editor while in the item/outfit tab will re-overwrite the changes made by this patch, so the patch will have to be reapplied again. Conversely, this patch can be safely applied without overwriting existing expanded outfit data.

Battle outfits aren't supported (yet?).

Extended Class Promotion EXP
The editor allows expanding the number of classes, but none of the expanded classes are ever considered as promoted classes in regards to experience gain calculations. This patch fixes that, albeit in a slightly unorthodox manner. The upper half of the extended classes (rather than the lower half) becomes considered promoted in regards to experience gains. Incidentally, MGCR and YGRT also become considered promoted.

WARNING: SPOILER!

Compatibility/other info:
Class ID 14 to 48 become considered promoted. This starts from SMR, ends at the halfway point of page 2, and includes Domingo's and Jogurt's classes. Originally, it only goes from SMR to the class right before Domingo and Jogurt.

This patch has no conflicts with the editor.

DETOX Copies Healing EXP
Even if healing EXP is modified in the editor, DETOX's EXP reward remains at 10. This patch makes it copy the minimum healing EXP setting instead.

WARNING: SPOILER!

Compatibility/other info:
This patch has no known conflicts with the editor.

EXP from healing can still be modified via the editor.

Extra data is added at 0x1C32B0.

----------

Change Reverter Patches
These patches undo the changes from the patches above and return the original game's functions. Patches that add data and end up expanding the size of the ROM do not have that filesize change undone.

WARNING: SPOILER!

Change EXP Cap per Action to 100 Reverter: return cap to 48
No Stacking Healing EXP Reverter: return to summing healing EXP from a single action
Static Combat EXP Reverter: return to having damage amount affect EXP
Muddle Enhancer Reverter: return MUDDLE's effect to a 25% ineffective against evasive targets
Multi Outfits per Character Reverter: return to the SF1 Editor's version of the code
Extended Class Promotion EXP Reverter: return to having MGCR, YGRT, and extended classes be considered unpromoted
DETOX Copies Healing EXP Reverter: return DETOX's EXP independence

Why do the Demon Masters even wield Holy Staves? That's something that's always bugged me. Because it makes absolutely no sense. They're totally evil and everything the opposite of what should be able to wield them. Yet the mages on the force can't wield them...For that matter the Master Mages shouldn't be able to wield them either. They should be equipped with Guardian Staves instead.

[Siel]

I reuploaded an actually functional multioutfit patch: there was one line of code missing from the patch itself to make it all work. (I had forgotten I was testing on a modified ROM with an equivalent of that line already included in a completely different location)

Is it possible to make a patch that ignores character level when calculating xp? Basically, would be nice to always get max regardless of level.

[Siel]

Here you go: a patch that makes the game ignore the actual level difference when calculating EXP, instead always awarding based on the maximum base EXP.
