Dr. Mario (BS)
\nROM Download<\/a><\/p>\nEDIT Oct. 15, 2012: I’ve attempted to do a more in-depth comparison with the previous dump, HOWEVER…<\/p>\n
It appears said previous dump, as it appears in the no-intro set, has a hacked header. I’m not entirely sure how this happened, but regardless…<\/p>\n
Here’s 7FC0-7FDF on the previous ROM:<\/p>\n
42 53 5F 44 72 20 4D 61 72 69 6F 00 FF 00 00 00
\n00 00 00 00 00 00 FF FF 20 10 33 02 CE B7 31 4B<\/p>\n
On the same addresses, these two redumps have the following bytes in common:<\/p>\n
82 63 82 92 81 44 B3 7D 83 8A 83 49 82 61 82 72
\nFF 00 00 00 00 00 ** ** 20 10 00 02 00 00 00 00<\/p>\n
(The ** are differing bytes. Their location is in the “date” area of the ROM, anyhow.)<\/p>\n
Notably, while the latter two’s headers are consistent with a “Deleted” game, the former has a header that just plain looks screwed up, especially with spelling “BS_Dr.Mario” the way it does. <\/p>\n
Furthermore, none of the ROMs load in BSNES, but while this is expected of the deleted header ROMs, the “hacked” header ROM causes an odd behavior which causes the ROM loader to crash.<\/p>\n
To boot up Dr. Mario closer to the way it was meant to be played, the header should look something more like this;<\/p>\n
82 63 82 92 81 44 B3 7D 83 8A 83 49 82 61 82 72
\nFF 00 00 00 00 00 ** ** 20 10 33 02 C7 B7 31 4B<\/p>\n
Note how the “hacked header” ROM does appear to have the checksum and maker values correct. Either the hacker attempted to restore these, or the header hack was based off a previously “pure” dump. This may need to be investigated.<\/p>\n
… To think we don’t even have as simple a ROM as this in it’s purest state? Sheesh…<\/p>\n
