Super Game Gear 73 in 1 [Sonic 2 ~ Street Fighter 2] (Unl)

I've been calling it "Super Game Gear 73 in 1 [Sonic 2 ~ Street Fighter 2] (Unl)", but the actual names are different:

The menu title is "SUPER 73 IN 1"

The title on the label is "GAME GEAR 73 IN 1" (three times!)

This is a single ROM image with two different multicarts. My hardware is wired the Sonic 2 way, but the only difference is which megabyte of the ROM is first and which mapper registers are used.

To dump it, I disconnected the game cartridge from the dumper and then reconnected it for each game's section of the ROM. I then wrote the three register values shown next to that game's menu item transcription, and then read out the game contents, using mapper register paging when the game was larger than 32KB.

This is a 2MB Game Gear multicart with a total of 42 games (though only 41 are reachable in each of the two supported hardware configurations.) It has one 512KB Game Gear game: Sonic The Hedgehog 2. It has one 256KB SMS-GG game: Jang Pung II. It has three 32KB Game Gear games: Pengo, Woody Pop, and Columns. The rest are 32KB SMS and SG-1000 games: Exerion (SG-1000) (modified to coexist in the same 32KB ROM mapping region with the menu), H.E.R.O. (SG-1000),  Hustle Chummy (SG-1000), Konami no Hyper Sports, Champion Ice Hockey (SG-1000), Loderunner (SG-1000), Machine Gun Joe, Monaco GP (SG-1000), My Hero, Fushigi no Oshiro Pit Pot, Road Fighter, Rock N' Bolt (SG-1000), Satellite 7, Great Soccer, Spy vs. Spy, Super Bubble Bobble, Teddy Boy Blues, Super Tennis, Trans-Bot, Zippy Race (SG-1000), Zoom 909 (SG-1000), Super Boy II, Champion Soccer (SG-1000) (modified to coexist in the same 32KB ROM mapping region with an unused alternate menu built for a different mapper chip), Astro-Flash, Bank Panic, Great Baseball, Bomb Jack (SG-1000), Champion Boxing (SG-1000), Championship Loderunner (SG-1000), Choplifter (SG-1000), Dr. Hello, Drol (SG-1000), Sega-Galaga (with the Sega title part removed), Ghost House, GP World, Hang-On, and Hang-On 2 (SG-1000).

Most of the games appear in the menu twice under different names. Some of the names are quite misleading, and also suggest that there may be other related multicarts containing the actual games those names suggest (the games suggested by those names also exist as SMS and SG-1000 games, for the most part, but aren't in this multicart.)

However, one of the games (Jang Pung II [SMS-GG]) isn't accessible via the menu and wouldn't work anyhow, since it requires different mapper hardware.

… but, there is a whole other menu in the same ROM built for different multicart mapper hardware that does support Jang Pung II, but does not include Sonic The Hedgehog 2 — which wouldn't work with the other mapper hardware anyhow, as it requires a Sega-style mapper. This other mapper hardware also expects the two 1MB halves of the ROM to be laid out in the opposite order.

First, a description of "Super Game Gear 73 in 1 [Sonic 2 ~ Street Fighter 2] (Unl)", the "Sonic 2" variant I have the hardware for:

Also on each menu screen:
PUSH ↑. ↓. 1. 2.

Also on the label:
GAMES SELECT ON SCREEN
GamePro Magazine Best Choice
GAME GEAR (with not-quite-right R-G-B ovals)

The menu system runs in native Game Gear mode, but many of the games run in SMS-GG mode. Text for the menu system is stored in the ROM starting around address 0x4000.

The menu has ten screens. Button 1 advances to the next screen, up and down move the cursor, and button 2 starts a game. Some of the menu items have text that is rendered in SMS-accessible VRAM outside the GG visible screen area. The GG-invisible portion is from the column marked with "┊" onward.

The mapper starts out in "menu" mapping mode. Making a game selection writes to FFFE twice and then writes 0x40 to FFFF, after which the mapper is in "game" mapping mode where it supports enough Sega mapper behavior to play the included games.

MAPBASE is a six-bit 32KB page offset into the ROM image. Its initial value is zero.

In "menu" mapping mode, the first write to 0xFFFE is in the range 0x40…0x4F and the second write is in the range 0x00…0x1F. In both cases the least-significant bit written is ignored.

Meaning of the bits in writes to 0xFFFE in "menu" mapping mode:

0x40: when this bit is set, the bits are interpreted as a high-part mapper write;
      when this bit is not set, the bits are interpreted as a low-part mapper write

High-part mapper writes:
0x80: this bit is ignored
0x40: this bit is always set for high-part mapper writes
0x30: these bits are ignored
0x08: when this bit is set, the game will launch in SMS-GG mode; otherwise, native GG mode
0x06: these will be the upper two bits of MAPBASE
0x01: this bit is ignored

Low-part mapper writes:
0x80: this bit is ignored
0x40: this bit is never set for low-part mapper writes
0x20: this bit is ignored
0x1E: these will be the lower four bits of MAPBASE
0x01: this bit is ignored

Writing 0x40 to 0xFFFF activates "game" mapping mode. No mechanism for returning to "menu" mapping mode afterward is known.

In "game" mapping mode, the Sega-style mapper registers only seem to work for MAPBASE in the range occupied by Sonic The Hedgehog 2. When the Sega mapper registers are used in those ranges, it is only able to address pages inside that game's range. Additionally, in the Sonic The Hedgehog 2 ROM region MAPBASE is always treated as if it points to the beginning of the region.

… now for the other hardware configuration! A description of "Super Game Gear 73 in 1 [Street Fighter 2] (Unl)", the "Street Fighter[ 2]" variant I don't the hardware for, but which uses the same ROM data with the two 1MB halves re-ordered:

Other than the first screen, the menu contents look identical to the "Sonic 2" variant. However this variant writes to different mapper registers for game selection, and the values it writes indicate that the ROM should be re-ordered by interchanging the first and second megabytes. I suspect it's just a jumper variant, but I haven't opened my cartridge to check.

The menu has ten screens. Button 1 advances to the next screen, up and down move the cursor, and button 2 starts a game. Some of the menu items have text that is rendered in SMS-accessible VRAM outside the GG visible screen area. The GG-invisible portion is from the column marked with "┊" onward.

In terms of visible menu contents, only item 01. is different.

The mapper starts out in "menu" mapping mode. Making a game selection writes to 8000 twice and then writes 0x40 to 4000, after which the mapper is in "game" mapping mode where it supports enough Codemasters mapper behavior to play the included games.

MAPBASE is a six-bit 32KB page offset into the ROM image. Its initial value is zero.

In "menu" mapping mode, the first write to 0x4000 is in the range 0x40…0x4F and the second write is in the range 0x00…0x1F. In both cases the least-significant bit written is ignored.

Meaning of the bits in writes to 0x4000 in "menu" mapping mode:

0x40: when this bit is set, the bits are interpreted as a high-part mapper write;
      when this nit is not set, the its are interpreted as a low-part mapper write

High-part mapper writes:
0x80: this bit is ignored
0x40: this bit is always set for high-part mapper writes
0x30: these bits are ignored
0x08: when this bit is set, the game will launch in SMS-GG mode; otherwise, native GG mode
0x06: these will be the upper two bits of MAPBASE
0x01: this bit is ignored

Low-part mapper writes:
0x80: this bit is ignored
0x40: this bit is never set for low-part mapper writes
0x20: this bit is ignored
0x1E: these will be the lower four bits of MAPBASE
0x01: this bit is ignored

Writing 0x40 to 0x4000 activates "game" mapping mode. No mechanism for returning to "menu" mapping mode afterward is known.

In "game" mapping mode, the Codemasters-style mapper registers only needs to work for MAPBASE in the range occupied by Jang Pung II. When the Codemasters mapper registers are used in that range, they must be able to address pages inside that game's range.

NOTE: mapper behavior for this variant is inferred from the ROM contents, since my cartridge is wired the other way (Sega/Sonnic 2 rather than Codemasters/Jang Pung II)

Super GG 21 in 1 [Sonic Drift] [Gold & Yellow Label]

I've been calling it "Super GG 21 in 1 [Sonic Drift] [Gold & Yellow Label] (Unl)" but the actual names are slightly different.

The label calls it:

SUPER GG 21 [in white text on a gold background]

The menu calls it:

SUPER 21 IN 1

I got my cartridge with no box or manual.

I qualify the name of Super GG 21 in 1 [Sonic Drift] [Gold & Yellow Label] with the first menu entry since there are apparently a bunch of very similarly-named 21-in-1 cartridges with different menus/games, and the label description only makes sense when you are looking at the physical cartridge

The ROM is 2MB (crc32:b0a898d4) and contains 18 distinct games; there are three 512KB GG games: Sonic Drift, Sonic 3, and Mortal Kombat; three 32KB GG games: Woody Pop, Pengo, and Columns; and twelve SMS games: Teddy Boy, Ghost House, Satellite 7, Spy vs. Spy, Machine Gun Joe, Astro Flash, Great Soccer, Super Tennis, Hang-On, My Hero, Pit Pot, and Great Baseball.

Dumping snippet: (disconnect and reconnect the cartridge between game_id values)

```
        local game_id = 0x03; // 0x00 ... 0x0f, 0x10, 0x20, 0x30
        local first_unlock = 0x48 | ((game_id & 0x30) >> 3);
        local second_unlock = (game_id & 0x0F) << 1;
        cpu_write(d, 0xFFFE, first_unlock);
        cpu_write(d, 0xFFFE, first_unlock);
        cpu_write(d, 0xFFFE, second_unlock);
        cpu_write(d, 0xFFFE, second_unlock);
        cpu_write(d, 0xFFFF, 0x40);
        cpu_write(d, 0xFFFF, 0x40);
```

The label also has a game list in black text on a yellow background:

```
01 SONIC DRIFT
02 SONIC 3
03 MORTAL KOMBAT
04 TEDDY BOY
05 GHOST HOUSE
06 SATELLITE 7
07 SPY VS SPY
