Hi! First, I'd like to announce that my Dead in the Air and Self Sneeze patches are now available for use with a Japanese ROM. If you prefer to play the Japanese version of the game and would like these two fixes, I recommend downloading them. I would make Japanese versions for the other fixes, except that they all either use free space on the Japanese ROM or involve editing monster or spell data. The only exception to this is the Save Point Glitch patch, which is already usable on either the US or Japanese ROMs.
Second, I was requested to try and fix Lenophis's broken Genjioff patch, and through the magic of the Internet Archive Wayback Machine, I found a copy of the patch and fixed the problems for the version that accommodates Assassin's Magic Damage Overflow fix. I was about to fix the regular version when I suddenly realized that the ROM I was using to fix the problems, which had tons of bug fixes already applied to it, did not have a fix for physical damage overflow, even though it did have a fix for magic damage overflow. I thought of applying Drakkhen's Physical Damage Overflow Fix patch, but quickly realized that not only was I unsure of which version to apply, but all three versions would conflict with both Genjioff and Assassin's Magic Damage Overflow fix patch which had already been applied.
So, taking all of this into consideration, I decided the best solution was to write a new patch that fixes every problem simultaneously, and thus was born the Ultimate Damage Fix. This fixes three problems all at once, with the first two being physical and magic damage overflow. The overflow would have resulted in a majorly OP character dealing a minute amount of damage because the damage requires 24 bits to calculate. The third problem is the one that would have been addressed by Lenophis's Genjioff patch, whereby the Genji Glove and Offering relics affect damage from all physical attacks regardless of whether or not the attack uses the attacker's weapon, e.g. Sabin's Pummel. All I did was take Drakkhen's patch that fixes both physical and magical damage by amalgamating the two functions and add some Genjioff tweaks.

This patch used to use up free space bytes C2/FBDB-C2/FBE1, but after some serious fussing about I managed to make this patch not use any free space at all. And because of that, I've also now included a version of this patch for a Japanese ROM. Anyone who's downloaded this patch already, you may download it again if you want, but you don't have to.

VERY minor update, I just removed two instructions after realizing they weren't needed, thus freeing up an extra three bytes, just for a slight optimization. There is absolutely NO need to re-download this patch, unless you want to save a few clock cycles in every damage calculation.

Noticed a minor calculation error which only affects damage from a character that has the Gauntlet equipped and causes a minute amount of damage to be lost because the multiplication by 7/4 is not quite the same. I have now fixed this. By the way, I had some difficulty rebuilding these archives this time around for some strange reason, so let me know if these patches don't work for you.

Never thought I'd update this patch again...there wasn't a problem to fix, really, I just decided to make some small adjustments with the rounding in the Relic adjustment calculations. The Offering cut-power-in-half function now rounds up and the Gauntlet's 7/4 multiplication rounds appropriately as well.
