MAPPER_GG_Super_12_in_1_FFFE for "Super 12 in 1 G…
…ame Gear [Mortal Kombat] (Unl)" I've been calling this "Super 12 in 1 Game Gear [Mortal Kombat] (Unl)", but the actual name of this Game Gear multicart is not entirely clear to me. The label and packaging are in English and Traditional Chinese. There is small sticker on the back of the cartridge which says "RC". This may suggest a Taiwanese release. It turns out this multicart is severable and also reversible. This produces three more multicart "ghost ROMs" using the same mapper and some or all of the same data: Just the first 2MB: Super 7 in 1 Game Gear [Bare Knuckle 2] [Super 12 in 1] (Unl).gg Just the last 2MB: Super 5 in 1 Game Gear [Mortal Kombat] [Super 12 in 1] (Unl).gg The last 2MB, followed by the first 2MB: Super 12 in 1 Game Gear [Bare Knuckle 2] (Unl).gg The menu is written such that it automatically adjusts to each of these subsets/layouts. Perhaps we will find physical carts containing these variations someday too? On the front of the box it says: SUPER [behind "12 IN 1" overlay] 12 IN 1 [overlaid on "SUPER"] GAME GEAR On the back of the box it says 12 IN 1 SUPER GAME GEAR On the cartridge label it says SUPER 12 IN 1 The menu does not seem to contain any collection title other than possibly "G.G.". The front of the box also has logos or titles for each of the 12 Game Gear games. The ROM is 4MB long. The back of the box also has screenshots for each of the 12 games captioned by the game names in both Chinese and English. These games are in the same order and use the same spellings as the list on the cartridge label. The English captions are shown beneath the Chinese captions. There is also a game list on the cartridge label with each entry written in both English and Chinese: [I hope you'll excuse any errors in transcription or translation, I don't know Chinese and used Google Translate and web searches a bunch to try to make sense of things!] ``` 1. MORTAL KOMBAT 龍爭虎鬥 (i.e. "Struggling Dragon, Fighting Tiger", the Chinese name of the Bruce Lee film "Enter the Dragon") 2. TERMINATOR II 未來戰士二 (i.e. "Future Soldier 2") 3. JURASSIC PARK 朱羅紀公園 (same pronunciation as 侏羅紀公園, i.e. "Jurassic Park") 4. TALES SPIN 頑皮熊 (i.e. "playful bear" or "naughty bear") 5.

TOM AND JERRY 湯姆歷險記 (i.e. "Adventures of Tom", same as a Chinese name for "Adventures of Tom Sawyer") 8. GLOBAL GLADIATORS 麥當奴小子 (i.e. "McDonald kid") 9. INDIANA JONES 聖戰奇兵 (i.e. "Crusaders", the Chinese name of the film "Indiana Jones and the Last Crusade") 10. HOME ALONE 寶貝智多星 (i.e. "Baby Wisdom", the Hong Kong name of the film "Home Alone") 11. DORAEMON 叮噹 (i.e. "Jingle" or "Ding Dong", one of the names used for Doraemon in Hong Kong and Taiwan) 12. BATMAN RETURNS 再戰蝙蝠俠 (i.e. "Fight Again Batman", the name of an early-1990's song by Alex To) ``` The PCB is marked "S32G1" on the solder side. On the component side there are two memories with their markings ground off, and three small DIP PLD's with intact labels: two are ICT PEEL18CV8P-25 and one is TIBPAL16L8-25CN. The PCB doesn't have any obvious manufacturer information, nor do the cartridge or box.

In "menu" mapper mode, writes to mapper register 0xFFFE (REG1) in the range 0x40…0x4F set the base 16KB page MAPBASE as follows: MAPBASE <= (REG1 & 0x0E) << 4 | (REG1 & 0x01) In menu mapper mode, writes to mapper register 0xFFFE (REG1) in the range 0x00…0x10 update MAPBASE as follows: MAPBASE <= MAPBASE & 0xF0 | ((REG1 & 0x10) >> 4) The initial value of MAPBASE is 0x00. The menu mode page mapping is as follows: 0x0000…0x3FFF: MAPBASE 0x4000…0x7FFF: MAPBASE | 1 0x8000…0xBFFF: MAPBASE Once 0x40 is written to 0xFFFF (REG0), the mapper switches to "game" mapping mode. This seems to implement a Sega-style mapper where the page numbers are OR'ed with MAPBASE. I do not know whether there is any way to return to the initial "menu" mapper mode after that. The initial values of the Sega-style mapper registers when switching to "game" mapping mode seem to be REG0 = 0x00, REG1 = 0x01. The game mode page mapping seems to be as follows: 0x0000…0x3FFF: MAPBASE 0x4000…0x7FFF: MAPBASE | (REG1 & 0x1F) 0x8000…0xBFFF: MAPBASE | (REG0 & 0x1F) All the games inside the ROM are exact copies of official releases except for two: TaleSpin has been modified to embed menu screen 1, and Doraemon has been modified to embed menu screen 2.
