The Space Invaders ROM currently in the WonderSwan DAT has 0x80000 bytes of FF on the front of it. I suspect it's probably an overdump and the correct size is 512KB rather than the current 1MB. The ROM works fine with the garbage data trimmed.

To be clear, I can't verify this against a cart, so it's possible they really did ship with a ROM twice as large as they needed, but seems unlikely at best.

Specs after trimming:
Size: 524288
CRC: 48A35572
MD5: 4C8D50F78BB435F0DE373F5A75AC75CE
