In Linux I use gparted (https://gparted.org) - It's posible make a CD/USB live if you don't use linux-. In Windows I haven't got any idea.
Forum to discuss about the ZX-Uno project
An Adlib/OPL3 implementation was added on Nexys4 version.
- Nexys4 (Artix7 xc7a100t-1) - runs at 160Mhz bus, 80Mhz CPU, 110Mhz(220MB/s) CellularRAM (16MB), 150Mhz DSP, ~6100LUT6 (9% from 63400), VGA12bit
The 160Mhz/150MHz FPGA image is obtained from the 120MHz/120MHz image by overclocking the routed design DCMs.
The OPL3 engine takes around 500LUT6, and the interface between the Next186 CPU and OPL3 is done with a NextZ80 CPU (~800LUT6).
The OPL3 engine drives 18 channels and 36 operators and needs at least 45Mhz clock. The 2-nd part of 4 operator channels is simplified, and the OPL3 rhythm is not yet implemented.
The access ports are 0x388 (bank 0 address), 0x389(bank 0 data), 0x38A(bank 1 address), 0x38B(bank 1 data). No delay is required between writes.
All supported DOS games and applications should be able play Adlib music with this Next186 SoC version.
I want to give credit to the MAME emulator developers. The MAME OPL3 emulator was the starting point for this Verilog implementation.
