MAME 0.287: Updated to the latest version.

Various bugs identified in version 2026.02 have been resolved

This version brings several fixes and updates to the original GroovyArcade (Substring). The main objective was to correct known bugs, update system components, and include new features to facilitate use in different setups.
LptKeycoder: Integrated support for parallel port keycoders, specifically the common diode-based control scheme for LPT ports.
OpenPPJOY (JAMMA Board): Driver included for interfacing with JAMMA hardware. For Flycast and RetroArch users (which do not natively support the four virtual SNES controllers created), the Arcade Game Pro utility is available in the GroovyArcade setup under Joystick Setup. This tool maps system controls, disables the original buttons, and converts them into keyboard commands; just configure and you're set.
Raspberry Pi Pico Support (NKRO Keycoder): A ready-to-use keycoder firmware is included in the shared/joysticks folder. It features NKRO (No-Key Rollover), allowing for simultaneous key presses without limits or "ghosting" conflicts. To use it, simply copy the file onto your Raspberry Pi Pico.
Dynamic Screen Swapping: A streamlined option to toggle between LCD and CRT (15kHz) monitors.
HDMI Audio Fix: If you are using an HDMI cable and experiencing audio issues, select your HDMI output in the GroovyArcade setup under Audio/Default Card, then activate the HDMI Audio Fix and reboot the system.
Updated Emulators: RetroArch and Flycast are now included and fully pre-configured.
Fightcade: Located at /home/arcade/shared/fightcade. Double-click Fightcade2.sh to make it appear under the "Games" section in the main start menu.
Smart Shared Folder: A system that allows you to add ROMs, BIOS, and custom configurations directly to the ISO before installation. The folder is located inside the ISO; anything placed there will be automatically copied, and existing files with the same name will be overwritten. This allows you to build a custom ISO with your preferred settings and games ready to go, eliminating the need for manual configuration after installation.
