So, I patched this in with a GBA > CIA converter since I realized I didn't actually have an IPS patcher, just a UPS one (aside from the CIA converter, that is). The end results were a ROM that didn't seem to have kaizo'd anything, couldn't save, and froze during the Diglet, uh, 'cutscene', a couple days after the magnemite job. Any ideas what might've caused this? Turning it into a CIA shouldn't be a problem, since that's what's needed for the 3DS to run GBA games, but who knows? Though a Fire Emblem randomizer converted this way runs with no problems, so hmm... Might be that the ROM itself is different (since I know the original place the ROM you used was hosted had to take down all their ROMs, so I looked elsewhere.) Still, in that case, it'd normally just fail to patch, so once again... Hmmm...

Either you need to have the correct original ROM or have to use Lunar IPS patcher (I have no experience using other patchers). If the very first dungeon puts you to level 1, then it's working.
