So
blueMSX is kinda a mixed bag that I have been toying with for a couple days.
ColecoVision,
MSX, &
MSX2 run (no luck with the
SG-1000 games I tested). Yet if you close the game out in
rgui and proceed to open another game you get a weird overlay of a frame from the last game you played. You can see it clearly in the video:
(audio is low so you may need to raise volume)
You can close out the emulator as a whole and restart a different game as a work around.
BIOS are required but if you
read the docs it explains how to get them and set them up. Instead of putting them in the
system directory you just want to put them in the
/switch/bluemsxnx/ folder on your microSD card.
