(MESS) gamegear: fixed detection of SMS games (via adapter) and added
support for connecting a SMS pad to the unit (via Gear2Gear port + adapter)
to play 2players games. [Enik Land]

out of whatsnew: needless to say, we are not yet in the position to use the
Gear2Gear port to link two gamegear units, so don't ask ;-)

1313 To do:
1414
1515 - SIO interface for Game Gear (needs netplay, I guess)
16 - Gear to Gear Port SMS Controller Adaptor
1716 - Sega Demo Unit II (kiosk expansion device)
1817 - SMS Disk System (floppy disk drive expansion device) - unreleased
1918 - Rapid button of Japanese Master System
r242572r242573
2423 - Software compatibility flags, by region and/or BIOS
2524 - Emulate SRAM cartridges? (for use with Bock's dump tool)
2625 - Support for other DE-9 compatible controllers, like the Mega Drive 6-Button
27   that has software support (at least a test tool made by Charles MacDonald)
26   that has homebrew software support
2827
2928 The Game Gear SIO hardware is not emulated but has some
3029 placeholders in 'machine/sms.c'

49General compatibility issues on real hardware (not emulation bugs):
50
51- Some ROMs have issues or don't work when running on a console of different
52  region;
53- Many Japanese/Korean or homebrew ROMs don't have the signature required by
54  BIOSes of consoles sold overseas;
55- Paddle games need to detect the system region as Japanese to work with the
56  Paddle controller;
57- Few games of the ones with FM support need to detect the system region as
58  Japanese to play FM sound;
59- The Light Phaser gun doesn't work with the Japanese SMS;
60- There are reports about Light Phaser working on the second Korean console
61  version, and a Korean advert shows support on the first version (Gam*Boy I,
62  although based on Japanese SMS);
63- The Korean SMS versions have Japanese-format cartridge slot, but only on the
64  first (Gam*Boy I) the region is detected as Japanese;
65- Some SMS ROMs don't run when are plugged-in to SMS expansion slot, through
66  the gender adapter;
67- Some SMS ROMs don't run when are plugged-in to a Game Gear, through the
68  Master Gear adapter;
