SG-1000 support for the MSX core?

Postby hyperterminal » Wed Jul 25, 2018 5:51 pm

In this thread I wrote that the MSX and SEGA's SG-1000 have similar hardware except for the sound chip.

The current MSX core for the MiSTer is based on the 1chipMSX.

A Japanese programmer wrote a VHDL file to add the SG-1000 sound chip to the 1chipMSX so that both MSX and SG-1000 games can be played (the latter needs a rom loader executed from MSX DOS).

The VDHL file can be downloaded from here: https://www.msx.org/forum/msx-talk/soft ... nd-sg-1000

Would it be possible to add this to the MiSTer core?

I will look.
Actually SN76489 PSG code is available long time and used in many other cores.
The key point is to integrate SG1000. I don't know MSX hardware and mostly relay on existing code and a few known to me details about MSX HW.
But i will see what can i do.
