+
+The below instructions to build Mednafen will attempt to use all of your machine's threads when compiling as the compilation process can take up quite some time, we disable optimization for the build as Mednafen has proven quite unstable when attempting to have the clang compiler on macOS optimize the application. The compilation procedure is as follows:
 
 ```
 ./configure --enable-ss
 
-make -j `sysctl -n hw.logicalcpu`
+make CFLAGS='-g -w' CXXFLAGS='-g -w' -j `sysctl -n hw.logicalcpu`
 ```
 
 At this point, the Mednafen binary can be found in the mednafen/src/ folder; you may manually copy/move it

 # Release Notes
 
+## New release 1.2 2023/11/24
+
+### New Features/Improvements:
+
+#### PC-FX Improvements / BugFixes: 
+ - Adds Azerty Keyboard support for Debugging functions
+ - Improve PC-FX palette editor - In debug mode, change PC-FX palette editor to show 16-bit values, with a colour swatch in the right-hand side to demonstrate actual colour (based on YUV)
+ - PSG Tweaks Update channel 1 frequency cache upon LFO frequency register writes (the way the channel 1 frequency and LFO frequency are combined is still inaccurate, however, causing frequency update timing granularity to be too high). Ported over MDFN 1.31.0 release
+
+#### PC-Engine Improvements / Bugfixes:
+- PSG Tweaks Update channel 1 frequency cache upon LFO frequency register writes (the way the channel 1 frequency and LFO frequency are combined is still inaccurate, however, causing frequency update timing granularity to be too high). Ported over MDFN 1.31.0 release
+- Backup memory visibility was previously inconsistent between HuCard and CDROM, and locking behaviour was not always correct. Now, physical memory at $1EE000 should give the "processor's view" of the memory, depending on lock/unlock status, and "Backup Memory" screen should show the actual data (Note: HuCard startup state is still default 'unlocked' which is not correct). Also, $1807 register writes should be able to re-lock memory
+- Remove Incorrect IRQ Acknowledgement scenario: TIMER interrupt is supposed to be acknowledged by write to $1403. Original code was also acknowledging it on reads from $1402, which was not supported by official documentation.
+- Fix junk appearing on PCE Debug palette screen 
+- Change Default gamesave name removing hash value for BRAM retention and compatbilty when doing PCE dev builds
+- Fix improper CDROM BRAM locking in debugger
+- PC Engine music player VU meter shows incorrect channels
+- Fix VU Meter display
+- Other minor changes to warnings and defaults
+- Add CI builds for Windows / Linux
+
+#### Other items:
+ - This release also contains several Wonderswan module updates that improve emulation accuracy
