Final Fantasy III: SwdTech Suspend 
- ~
- Share
Final Fantasy III: SwdTech Suspend is a fan-made patch for the Super Nintendo version of Final Fantasy III. Released on April 23, 2023, by SilentEnigma, the patch enhances the SwdTech charging system by allowing players to switch characters during the charge process. This modification enables other characters to receive commands, improving gameplay efficiency while maintaining the original mechanics.
The SwdTech charging mechanic in FF3us is often criticized for its slow charge time and the inability for other characters to receive commands while charging. This patch modifies the mechanic by allowing the player to switch characters mid-charge.
While the SwdTech gauge is charging for a character, the player may now press the X or Y button to switch between characters. The gauge position is held in the background while other characters receive commands. Once input returns to the charging character, the SwdTech gauge window automatically reopens. The gauge will resume from the next tier number past its previous position.
The feature is disabled if there are no other characters ready for input. A character's SwdTech gauge resets if the player cancels the gauge window or the character becomes incapacitated.
Archive includes an *.ips patch for both headered and non-headered ROMs.

0. DESCRIPTION
________________________________________________________________________________
This patch modifies the SwdTech charging mechanic in FF3us (FF6) for SNES.
SwdTech is often criticized for its slow charge time and the inability for other
characters to receive commands while charging. Modern rereleases of FF6 address
this by allowing the gauge to charge in the background.
This patch is intended to improve the mechanic in the SNES version by adding
character switching support to the SwdTech gauge window.
While the SwdTech gauge is charging for a character, the player may now press
the X or Y button to switch between characters. The gauge position is held in
the background while other characters receive commands. Once input returns to
the charging character, the SwdTech gauge window automatically reopens. The
gauge will resume from the next tier number past its previous position.
This allows the player to give other characters commands without losing progress
on any charging SwdTech gauge(s).
The feature is disabled if there are no other characters ready for input.
A character's SwdTech gauge resets if the player cancels the gauge window or
the character becomes incapacitated.
This patch uses 4 additional bytes of RAM to hold the value of each character's
SwdTech gauge progress.
