MESS 0.148u5
rx78 driver
BS-BASIC cartridge required!

Here a new autoboot command example:

Quote
Mess.exe rx78 -ab "\n\n\n10 PRINT CHR$(6):COLOR,0\n20 C=1\n30 FOR I=0 TO 500\n40 W=INT(RND(1)*191)\n50 X=INT(RND(1)*183)\n60 Y=INT(RND(1)*191)\n70 Z=INT(RND(1)*183)\n80 LINE[C]W,X,Y,Z\n90 C=C+1\n100 IF C>7 THEN C=1\n110 NEXT I\n120 END\nRUN\n" -autoboot_delay 2 -cartridge "C:\Emulator\Bandai RX-78\BS-BASIC.ROM"
It writes automatically the Basic program (Graphic demonstration) and run it.
Of course, the path for the ROM (cartridge) must be adapted.
