Les changements:
Sega 32X (New)
– 32X games run through the PicoDrive library (`Plugins\picodrive_libretro-64.dll` or `-32.dll`, included). A game with a SEGA 32X header (`.32x`, or a `.bin`, `.zip`, `.7z`) is recognized by itself.
– Works for 32X games: save states, Auto Resume, rewind, input recording, video / audio / GIF recording, screenshots, region, FM chip (YM2612 or YM3438), Console Model, High-Quality FM, 3-Band EQ, low-pass filter, Sample Rate, NTSC filter, LCD ghosting and all render filters and shaders.
– Cheats and Cheat Search for a 32X game: the cartridge ROM, the 68000 work RAM and the SH-2 SDRAM (a Memory choice in Cheat Search).
– PWM sound: Mute PWM Sound (Audio > Mute, Ctrl+P) and a PWM Preamp slider in Levels and Latency. The FM and PSG levels work too.
– Netplay for 32X games.
– VGM recording of the FM, PSG and PWM.
Sega Pico (New)
– Sega Pico is a console of its own in the game list, the file dialogs and the folders. Pico games are found by their header, also inside `.zip` and `.7z` files, and the scan stays instant (the headers are read in the background).
Cheats
– Work RAM byte codes (`aaaaaa:dd`), a clear Status for every code, sortable columns (the `#` number stays with its cheat), and Similar Cheat Files (load one to replace the list, or insert its cheats).
– Export… saves the list as a `.cht` file; RetroArch `.cht` files are read; Cheat Code Converter lists a code as Raw, Action Replay and Game Genie in columns; Size All Columns to Fit.
– Cheats work in netplay (both PCs need the same ones on; they are compared when connecting).
– The red screen is fixed. Many games check their ROM when they start, and a code already in the ROM made them show a red screen. ROM codes now go in after the game has started: after the first button press (two seconds at least, twenty at most), also after a reset.
– Cheat Search: First Scan and Next Scan, the scan is kept when the window is closed (until the game stops), and the Memory choice is remembered for the game.
Recording and VGM
– VGM recordings begin with the state of the sound chips (the FM chip, PSG and, for 32X, the PWM), so a recording started mid-game sounds right, and the end of a recording releases every held note. Shift+F10 starts a VGM recording.
– Video recording options (size 1x to 4x, quality, and shape: the console’s own, 4:3 or 16:9 widescreen) in Settings > Options; 2x is the default size. Screenshots: Screenshot Output (Raw, Corrected, Final) and Screenshot Size (1x to 4x).
Picture
– More render filters, sorted by name in a sub-menu for each family: Super Eagle, Super 2xSaI, 2xSaI, the real HQ2x/3x/4x, LQ2x, xBR 2x/3x/4x, ScaleFX 3x, CRT Geom 3x/4x, bicubic Catmull-Rom, Mitchell and B-Spline 3x/4x, Sharp Bilinear 3x/4x, Lanczos 3x/4x, Scanlines 3x/4x, Glow Scanlines 3x, CRT Aperture Grille and Shadow Mask, LCD Grid 3x/4x.
– Interlaced Mode (single or double field): a double-resolution picture (Sonic 2’s two player mode) no longer shakes or blurs, and moving sprites are no longer drawn in blocks. Rewind works with it.
– Picture Adjustments window (Video menu): Contrast, Saturation, Gamma and Hue sliders, with a Restore Defaults button.
Look and Feel
– Modern style reworked: flat rounded controls, a rounded chosen item in menus, system menu colors.
– Accent color everywhere: list rows, drop-downs, slider knobs, and (in Classic too) check boxes and radio buttons. 19 accent colors.
– Colorful Icons option for the menu icons, toolbar and favorite star.
– Large interface polished: menus, icons, a dark menu frame, bar titles, a wider Settings window.
– Sizes and text follow the display scale (menus, toolbars, status bar, dialogs).
– Dark menu bar in fullscreen with no white flash.
– Radio items in menus show a dot (Render Filter, Select State Slot and others).
Settings and Controls
– Controls: the Advanced tab is now Extras (ports and combos).
– Turbo Rate: Slower, Slow, Medium (default), Fast and Faster, 7.5 to 30 presses a second.
– Rewind Speed: Slow, Normal, Fast or Very Fast.
– Always on Top moved to Settings > General and the View menu.
Others
– User Guide (was the Menu Guide): a formatted page you can resize and maximize, with the names of items in bold, the Settings, Controls, Cheats and Netplay windows, the BIOS and Firmware files last, right-click Copy and Select All, and the logo and credits on the first page.
– A few hidden surprises were added.
Notes
– BIOS files are not included (only Mega CD games need them): see `readme.txt`.
– Based on Genesis Plus GX by Eke-Eke, core by Charles MacDonald; 32X through PicoDrive by Dave, notaz, irixxxx and others. Same license terms as Genesis Plus GX: source must accompany modified redistributions, and it may not be sold or used commercially.
