GenX v1.1.2 is released. A new Sega emulator that can run Genesis, Game Gear, 32X, and Sega CD.

Features:
Systems
Genesis / Mega Drive cartridges. That includes battery and EEPROM saves and the SVP chip used by Virtua Racing.
32X. GenX has its own start-up code, so the three 32X BIOS files are optional.
Sega CD / Mega-CD from .cue/.bin, .iso or .chd. Disc swapping works, and you can boot the BIOS with no disc to reach its CD player and memory manager. Sega CD 32X discs work too.
Game Gear, and Master System through the same core.
ROMs can be loaded straight from .zip files.
Playing
10 save states per game.
Rewind and fast forward while a key is held.
Turbo (auto-fire).
Keyboard, XInput (Xbox-style) and DirectInput controllers.
3-button and 6-button pads, with a saved controller profile for each player.
Light guns. The Menacer and the Justifier are aimed with the mouse. Two players can each use their own mouse with a Justifier.
Miracle Piano Teaching System, with an on-screen keyboard. The keyboard can be opened in its own window and played with a mouse, or by touch on a touch screen like a tablet.
Game Genie codes for the Genesis, Game Gear and Master System, kept per game.
Multiplayer
Netplay. Two players over a network or the internet, on Genesis, 32X and Sega CD games. The session is encrypted with a passphrase, and controller types and light guns are carried over.
Gear Link. Two Game Gears side by side, joined by the link cable, for two players on the same PC. Gear Link also works over netplay, with each player on their own PC.
Display and sound
Window scale from 1x to 4x, plus fullscreen.
Aspect ratio: stretch, 4:3, 16:9 or a custom size.
CRT scanline filter and pixel smoothing.
FPS counter, and dark or light theme.
The console's own low-pass output filter (optional) and a volume control.
Mute switches for each sound chip, and recording to WAV.
Diagnostics
One key (Ctrl+L) writes a diagnostic log covering the loaded game, the controllers and where your key presses went.

GenX Changelog:
Sega CD fixes. Nothing else in the emulation changed.
Download: GenX-v1.1.2-win64.zip. Unzip it anywhere and run genx.exe.
To update, replace your old genx.exe with the new one. Your settings and
saves stay where they are.
Fixed
Crash when opening a Sega CD disc. GenX closed without a message when a
disc sat near a file or folder whose name has certain characters, such as an
accent stored as a separate mark (some "Pokémon" names) or Japanese text.
Japanese and Southeast Asian Sega CD BIOSes now start. They used to stop
on an error such as "This is a PAL-compatible Mega CD for exclusive use in
Southeast Asia", because GenX always presented itself as a US or European
console. GenX now becomes the console the BIOS belongs to.
Japanese discs get a Japanese BIOS when your BIOS folder also holds the
Southeast Asian one. Some BIOS packs name the Southeast Asian BIOS
jp_mcd1_9112.bin, which GenX used to pick first.
The BIOS tab in Configure shows the BIOS each region's discs will
really use.
Thanks to the player who reported the Southeast Asia error.
