The YRW801 requires 2MB, so all the space in the EPCS16. Removing the mp3 firmware does not help.

Eugeny is still doing changes on the firmware. We are now able to set the default OPL4 firmware boot option from the regular0 firmware before you change to the OPL4 firmware.

When you use the OPL4 firmware, warm booting (pressing reset on your MSX) now limits the boot menu wait time to 0.5 sec (so faster boot times).

Also check _NETOPL4IMG and the _NETHELPOPL4IMG commands for the default OPL4 image settings.

You will need the latest update.bin from 2021-11-07 and gr8net-fpga-opl4.bin from 2021-11-04 or this to work.

Eugeny has added a 8bit version of the YWR801 rom for users with a 2MB flash chip. It is hard to hear the difference!

Also listing the flash contents now has a option to skip CRC check for faster listing: _FLLIST(1)
