Add mapper detection for "Mega Mode Super Game 78 (KR) [SMS-MD]"

Add mapper detection for "Mega Mode Super Game 78 (KR) [SMS-MD]"

This is yet another SMS-MD multicart full of SMS games. It runs entirely in SMS mode

A consistent name for indexing would probably be "Mega Mode Super Game 78 (KR) [SMS-MD]"

I've been calling it "Super Game 78 - Mega Game 16 (KR) [SMS-MD]" but the actual names are in Korean:

슈퍼게임 78 (Super Game 78) [cartridge label top]

메가게임16 (Mega Game 16) [cartridge label front]

메가모드 슈퍼게임 (Mega Mode Super Game) [menu title]

A different menu title 메가모드 게임머쉰 (Mega Mode Game Machine) very briefly flashes at startup before it is replaced, likely indicating some genetic relationship to multigame SMS arcade boards

This is a "space menu" multicart of SMS games in a Mega Drive-shaped cartridge. It runs entirely in SMS mode.

Dumping was via a temporarily hacked version of the Sanni Open Source Cart Reader https://github.com/sanni/cartreader

The SMS dumping script was temporarily modified as follows to allow FFF5 outer paging and 2MB dumps:

The 2MB turned out to be overdump, as the ROM is only 1MB and contains just 15 distinct games

This uses the multicart mapper known to Meka as Mapper_SMS_Korean_MD_FFF5

Outer paging is by mapper register 0xFFF5 which can reach the whole 1MB ROM in 32KB pages. Inner paging is by Sega mapper registers but can only read 128KB in 16KB pages. Outer and inner paging seem to combine by shift and bitwise OR. The FFF5 register remains active even after the initial write

This 1MB multicart contains a menu and 15 SMS games: 32KB Satellite-7, Astro Flash, Machinegun Joe, Pit Pot, Teddyboy Blues, Great Baseball, Super Arkanoid, Seishun Scandal, and Ghost House; 64KB Super Tetris; and 128KB Makai Retsuden, Rambo, Inja, Double Target, and Fantasy Zone

The menu has an animation showing "SELECT MENU" and alternately "선택하세요。" (i.e. "Choose.")

The menu has five screens with 16 items per screen except for the last screen which has only 14
