# News
November 2020: move to latest VGA_t4 library for stable HIRES support<br>
- support USB mouse added to Amiga/Atari ST emulation
- Amiga sound improved (freq drifting less audible)
- Atari ST now support 640x200 and 640x400 (B/W) modes with double buffering!!!
- Amiga now support 640x240 mode for cleaner workbench!!!
Mid October 2020: Most emulators are now supporing VGA with sound on the Teensy4.1<br>
Experimental I2S sound driver has been added to the VGA_t4 library with minimal DMA disturbances.<br><br>
If you are experimenting issues (e.g. image flashing out, crash after few minutes):
- try compiling for smallest code iso faster
- activate/Deactivate USE_VIDEO_PLL option in vga_t4.cpp
<br>
e.g.:<br>
- ST emu: compile for "smallest code" and USE_VIDEO_PLL<br>
- Amiga emu: compile for "smallest code" and don't use USE_VIDEO_PLL (to avoid video artefact, sound distorsion still has to be fixed)<br>
- Doom: compile for "faster" and USE_VIDEO_PLL<br>
- ST emu: compile for "smallest code"<br>
- Amiga emu: compile for "smallest code"<br>
- Doom: compile for "faster"<br>
Atari ST emu has now better sound support!<br>
