[clobber]

Zaxxon 3-D (World).sms (CRC32: 0xA3EF13CB) crashes on load with EXC_BAD_ACCESS somewhere in https://sourceforge.net/p/crabemu/code/HEAD/tree/trunk/CrabEmu/src/consoles/sms/mapper-koreanmsx.c#l160

CrabEmu r253, debug build in Xcode 6.4 on OSX 10.10.4

Well, this game certainly shouldn't be using that mapper (much like the report about Astro Flash). Also like that other report, it is fixed in r254.
