Seems that some people have problems building a GS ROM image. I've written a
small BASIC program that is doing the work for you. (Specify the ROM version
you're using in line 10.)
 
10 ROM = 1
20  HOME
30  GOSUB 1000
40  VTAB 2: PRINT "Building GS ROM image. Please wait..."
50  IF ROM = 1 THEN BANK = 254
60  IF ROM = 3 THEN BANK = 252
70  FOR I = BANK TO 255
80  POKE 783,I
90  FOR J = 0 TO 7
100  POKE 777,J * 32
110  CALL 768
120  PRINT  CHR$ (4);"BSAVE APPLE2GS.ROM,A$2000,B";(I - BANK) * 65536 + J *
     8192;",L$2000"
130  NEXT J
140  NEXT I
150  VTAB 4: PRINT "Done."
990  END
1000  FOR T = 0 TO 18: READ X: POKE 768 + T,X: NEXT T
1010  RETURN
1100  DATA  24,251,194,48,169,255,31,162,0,0,160,0,32,84,0,254,56,251,96
 
Hope this helps.
