Metal Gear - UNROM to MMC3 MapperDescription

Don’t think this is gonna be a 100% Gold Remake, it’ll have its differences. Extra battles (some’ll be optionals, tough but rewarding), Hoenn Pokemon (in every area, and hard to find) New areas, Remapped some dungeons (so your old guides wont work) , Extra recurring characters (some’ll hate you, some’ll help you)

Note that the hack is incomplete but feel free to enjoy the hack as-is.

Converting Metal Gear from UNROM to MMC3

UNROM bankswaps are being done by '99D0FF' at $1C964 & $1C96D
$1FFF2 & $1FFFA have '8DD0FF' $1FFFD has '8D0080'

$7F80 will have to have a portion of the Reset Vector here, no free space within HW bank.

OK HERE ARE MY PASTES

Portion Of Reset Vector, Along With MMC3 Setup Routines
$7F80 = AD022010FB20F7C0A2FF9AE8A90785818A8680A0CF918088D0FBC681A681E002D0F3
$7FA2 = A9008D00808D01808D00A08D01A08D00C08D01C08D00E08D01E0A2058E0080BDBDBF8D0180CA10F44C2AC0000204050607

MMC3 Bankswap Routine
$1C018 = A9012010C04C70BF0A48A9068D0080688D0180090148A9078D0080688D0180600000

All MMC3 JSR Bankswap Routines
$1C964 = 2010C0
$1C96D = 2010C0

The following ones I feel are not used by the rom, but i'm changing them anyway

$1FFF2 = 2010C0
$1FFFA = 2010C0 EAEAEA

DONE! Metal Gear is now MMC3! :-D
