document that ketsui roms exist with different fill in the unused areas [Artemio Urbina]

I haven't added it as a new set, at least not for now.

trunk/src/mame/drivers/pgm.c:
   // an alt version of this rom exists with 0xff fill in the unused area after 0x1443bc rather than random data like the one above, there are no code changes.
