So, it's up there almost working. The (J) version definitely works fine. The (U) version however, has a little problem, very likely a RAM clash somewhere, that makes the game freeze at some places. I tried to locate the RAM clash, but couldn't find it. I'll have to look harder. Also, the opera is back to the SNES version but with a surprise, and the ROMs are not extended. I'll also make a (E) version with the same opera, so in the end it'll be exactly like FF5 Advance with two patches for (E) version, and one for (U) and (J) versions.
