Needed to type out the code manually, but it seems to work. Only did the one starting on page 15(bg gfx example code). Did the original, then fixed it so it compiles with vasm6502_oldstyle.
It took a while to get working, vasm6502_oldstyle IS case sensitive. And example: Gtest1 and GTest1 are not considered the same.
