GenX v1.1.3 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:
Play your real Sega CD discs. Nothing else in the emulation changed.
Download: GenX-v1.1.3-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.
New
Sega CD discs straight from your PC's CD/DVD drive. Put the disc in,
choose File → Open ROM → Sega CD from drive, and pick the drive. GenX
reads the game and its CD music from the disc, reading ahead while you play
so the drive keeps up. A USB drive works too.
Changing discs: use Sega CD → Swap to disc in drive, or just put the
next disc in the drive. GenX swaps it in as a real Sega CD would.
Front ends: genx.exe E:\ starts the disc in drive E:.
You still need the Sega CD BIOS for the disc's region.
If your drive or a disc doesn't work, please
open an issue with the drive's
make and model and the game.
