EDIT: I was wrong earlier about the initial value of the mapper register due to a side-effect of my dumping script. Actual initial value seems to be either 0x7f or 0xff, bit 8 seems to have no effect — however this way doesn't work in the emulator due to differences in initial CPU + RAM state. For reliable operation MPR is initialized to 0x01 in the emulator.
I have been calling it "Super Game 45 ~ Super Game (KR)" while working on it. The actual name is Korean, though:
슈퍼게임４５ ("Super Game 45") [top label]
슈퍼게임 ("Super Game") [menu]
Front label has a picture with cartoon zoo animals and a zoomorphic character in a pith helmet. It has an MSX-style "Mega Rom" mark, and says 겜보이 ("Gam*Boy")
Menu side art has a space ship with animated rocket flame, stars, planets, and a couple people — taller one at the left edge with short green hair, black lips, and a light cyan clothing with red collar, shorter one to the right and partly obscured by that one with long orange hair, red lips, and green clothing with pink trim
The menu has 46 items, with several for some of the games. The final menu entry (46) restarts the menu, including on real hardware. I suspect the multicart uses a RAM-based hook for applying simple trainers, but I haven't yet gone hunting for it. Some games have multiple entries in the menu that start them at different levels/with different settings
Text at the top of the menu alternates between "SELECT MENU" in English and "선택하세요."/seontaeghaseyo in Korean (Google Translate says that means "Choose." or "Please select.")
The games seem to be a mix of MSX games (using an MSX BIOS replacement that is stored in the first two 8KB ROM pages) and My Card / Sega Card games. Text in the ROM image and in some of the games suggests this multicart may be the work of Screen Software and/or Clover. No manufacturer/publisher info appears on the cartridge label and the injection molded cartridge shell is devoid of markings. I have not yet attempted opening it to inspect the PCB

mapper scheme:
mapper register MPR is written at $FFFE, initial value seems to be either 0x7f or 0xff, bit 8 seems to have no effect — however, Meka's initial CPU register and RAM state means this game only works when MPR is initialized to 0x01
the ROM contains 64 pages, each 8KB — though only 63 are distinct, since pages 0x21 and 0x32 have the same contents
8KB page at $0000: ((MPR & 0x40) == 0x40) ? (MPR & 0x1e) * 2 : 0

Squirrel script fragment I used to dump this cartridge via the Tengu Game Gear cartridge bus adapter:
function cpu_dump_sg45(d, rom_size, banksize, offset)
{
// Korean Super Game 45 ~ Super Game
local max_dump_size = 0x100000;
local block_step = 0x8000;
local bias = (offset - 1) * (max_dump_size / block_step);
local mapper_register = 0xFFFE;
for(local a = 0x0000; a < rom_size; a += block_step)
{
local i = bias + (a / block_step);
cpu_write(d, mapper_register, 0x40 + (i * 2));
cpu_write(d, mapper_register, 0x40 + (i * 2));
cpu_read(d, 0x0000, block_step);
}
}
