Not sure if that's the right place to say this, since it's more about fixes than new bugs, but I didn't want to start a new topic because it's not about my work.
But have you ever read about Inu (or Inu's Sandbox)? It's a person from Japan who worked on various patches and programs for the SNES FFs (ever heared about FF4/5/6 analyzer/decoder? This guy released those for FF4/5/6 Advance).
A huge collection of ips patches for FFV is actually downloadable on romhacking.net since 2010 - yet I haven't seen this guy mentioned here.
Although the description reads...
This is a collection of bugfix and improvement patches for the Japanese version of Final Fantasy V for the Super Famicom from Inu?s Sandbox.
... they still work for RPGe's translation (at least the ones I tried). Some of Inu's fixes have also been made by other people similarily, like Butz' Blue Mage sprite fix, or Power Drink fix. But there is also stuff I haven't seen elsewhere, like an improved Item sort system (It sorts with the following order: Items - Knives - Swords - Spears - Axes&Hammers - Katanas - Rods - Saves&Maces - Bows - Harps - WHips - Bells - Exotic - Shields - Helmets - Armor - Accessory).
Or another fix which deals which the teleportation bugs of Qelb (by disabling Teleport) and Ghido's Dwelling / Library of the Ancients (by Teleporting outside the Library).
*Unfortunately, the Mineuchi/SwordSlap fix does not work - Mineuchi is unchanged while the normal "Fight" command of both characters and monsters inflict paralyze*
Still, I think this patch collection needs more attention. Also, this might prevent people to work on patches/fixes which were already made.
