He updated the patch to 1.01, then again stealthily updated it (also named 1.01) because of bsnes or some-such.
Anyway the game is incredibly buggy, I doubt it's been play tested at all. I've hard patched a ROM using both 1.0, mziab custom patch, and now 1.01 (both versions) to a No-Intro ROM, and using SNES9x as my emulator, and I still get constant emulator hardlocks and graphical glitches on menus/dialog at seemingly randomly points, so either it's the patch, SNES9x, or the game, but I just don't care enough to troubleshoot which it is since the games not all that fun in the first place.
So just letting you know that I too have been patching translations and hacks for years with no problem, but this one has been a pain, so you're not alone.
EDIT: Okay for shits and giggles I just tried a clean "Super Robot Taisen Gaiden - Masou Kishin - The Lord of Elemental (Japan)"
ROM and that locks up Snes9x sometimes too, so it's the emulator, and not the game or patch. So Snes9x isn't a good emulator to use with this game I guess.
