Unchained Melody multicarts

Unchained Melody multicarts
Platform: Unlicensed NES This game has debugging material.

A series of multicarts with lots of repeated games that may or may not contain the song Unchained Melody.

Note: Leftover title screen character graphics from other versions will not be covered.

83-in-1

An internal selftest program can be accessed by pressing Select + Start on the menu. It performs a test of the CHR data, PRG data, mirroring support, and banking support.

100-in-1

An internal selftest program identical to the one found in 83-in-1 can be accessed by pressing Select + Start on the menu. Were the numerous other similarities not convincing enough, the lack of changes to the selftest program makes it pretty clear that this multicart is a hack of 83-in-1, and a very lazy one too, as the PRG & CHR tests fail due to their respective checksums remaining untouched, not to mention the multicart name not being updated to reflect the increase in repeated games.

150-in-1

150-in-1 contains an updated version of 83-in-1s selftest program, still accessed by pressing Select + Start on the main menu. The updated selftest program performs additional tests due to this multicart using a more complex MM3-based mapper, and is also in color. Bizarrely, the revision is specified below the multicart's title as "VER LOVE".

1994 Super HIK 300-in-1

Hold Left + Start and press B on the menu to see its revision number. 1994 Super HIK 300-in-1 has a revision number of 1.1, the same as 10000000-in-1 and the earliest dumped revision of 9999-in-1.

500-in-1

Regular	Alternate

Before the tilemap and palette for the title screen are loaded, the multicart checks if 0x02201A (0x200A in CHR-ROM) is equal to zero (it's set to 08 by default, although any non-zero value will display the default 500-in-1 title screen). Setting it to zero will display an alternate 190-in-1 title screen, which has a brownish color and no palette blinking.

9999-in-1

1.1	1.2	1.3

Hold Left + Start and press B on the menu to see its revision number. There are currently three dumped revisions of 9999-in-1, ranging from 1.1 to 1.3.

9999999-in-1

Hold Left + Start and press B on the menu to see its revision number. 9999999-in-1 has a revision number of 1.0, an earlier revision than any other known Unchained Melody multicart.

10000000-in-1

Hold Left + Start and press B on the menu to see its revision number. 10000000-in-1 has a revision number of 1.1, the same as 1994 Super HIK 300-in-1 and the earliest dumped revision of 9999-in-1.
