The Second VGMPlay uses a TSR Handler, so it can not work unless you install the TSR for it.
But something is weird there, why it shows Using LPT ?
Maybe you have a older version ? i attached mine.
Thanks for sharing your Information on SN76489,
i use a small attiny13 mcu for now and cut the sn76489 from bus.
the attiny13 can be programmed to detect the ce pulses and enable the latch and disables it on reset.
i also tried with a flipflop before, but it did not work out for me, the sound enabled on 2 machines during bios check because it did access the #2 dma controller on boot.
especially on a Epson POS PC who did multiple accesses.
You can also try out TNDY TSR, which does not require EM386 or QEMM386 at all, note that its not combatible with certain drivers, smartdrv for example.
i don`t know if latest code is on the page so i attach it here too.
