Subject: [PATCH] there was a very old bug in the emulator which didnt matter
 due to luck but which caused unexciting mappers not to store their (empty)
 state correctly in the savestate. WriteStateChunk() returned 0 when there was
 an error in SubWrite(), even though it shouldve written a 5 to account for
 the overhead
