ben-blinkenlights/ubb-vga/regs4740.h
Werner Almesberger 957491d209 ubb-vga2: instead of pointers to registers, use pointer plus offset (via macros)
- regs4740.h: macros to access selected Jz4740 registers
- ubb-vga2.c: replaced all pointers to registers with access macros
- ubb-vga2.c (line_cycles): we now seem to be 0.1 us slower
