+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+## [2.0.3]
+### Added
+    - Display a warning when loading an Elf that is not clean.
+    - Added to the lib folder, common libraries that are usually missing.
+### Fixed
+    - Missing patch in HOD-EX.
+    - Alows to run a game that does not support Card reader if option enabled in conf file.
+
+## [2.0.2] 2025-01-27
+### Added
+    - InitialD 5 SBRY added.
+    - HOD4 SP CPU Frequency fix.
+### Fixed
+    - Fixed a bug when a game uses GLUT and the conf was set to NO_SDL 1
+    - Fixed a bug in Let's go Jungle when GPU was nVidia and Mesa was set as shader patches.
+    - Exclude resolution patches when the resolution is the game's original resolution.
+    - Reload with Right mouse click for Rambo and 2Spicy with SDL.
+
+### [2.0.1] 2025-01-23
+### Added
+    - HOD4 Custom crosshair.
+    - HOD4 CPU frequency fix  (Configurable via config file).
+    - HOD4 New resolution patch that fixes Boss battle and scales from 1280x768 instead of the lower resolution.
+    - Built in Logos and fonts (no more nee to use Lucida/SEGA_KakuGothic-DB-Roman_12 and logo.tga).
+    - Outrun 2 Easy network config from the conf file (can set your IP address in the config file and the loader will set it in the eeprom for you).
+    - Card Emulation for VT3 and R-tuned.
+    - All the now games work inside an SDL window now,  unless it is disabled in the conf file.
+
+## [2.0] - 2024-12-24
+### Initial Release
+- First official public release.
+- Features of the loader:
+    - Dynamic shader modification allowing games to work on Intel, nVidia and AMD
+    - 5.1 Surround Sound Support
+    - Dynamic resolution patching allowing most games to scale properly in HD
+    - Original cabinet support with pass through of JVS and FFB
+    - Network play
+    - Both simple X11 and advanced evdev input system allowing for ready-to-play keyboard and mouse support or mapping of any controller

+
+### Ghost Squad / 2Spicy
+
+You may have sound issues such as the game complaining that the system cannot open `/dev[/sound]/dsp`. You **must not** use the `libopenal.so.0` files that came with the game, please delete those if you've moved them into your game folder. Do the following:
+
+```
+sudo apt install pipewire-audio-client-libraries:i386
+sudo cp /usr/share/doc/pipewire/examples/alsa.conf.d/99-pipewire-default.conf /etc/alsa/conf.d/
+```
+
+Then in the game folder you must create a symlink to the `libopenal.so.1` library installed on your system:
+
+```
+ln -s /usr/lib/i386-linux-gnu/libopenal.so.1 libopenal.so.0
