The following macro is used to ensure the game switches to the correct PPU nametable and pattern table for drawing the icon bar: SETUP_PPU_FOR_ICON_BAR It checks whether the PPU has started drawing the icon bar (which it does using sprite 0), and if it has it switches the PPU to nametable 0 and pattern table 0, as that's where the icon bar tiles live. If bit 7 of setupPPUForIconBar is set, it also affects the C flag as follows: * If bit 6 of PPU_STATUS is clear (sprite 0 has not been hit) then the C flag is set to bit 7 of PPU_STATUS (which is set if VBlank has started) * If bit 6 of PPU_STATUS is set (sprite 0 has been hit) then the C flag is cleared There are no arguments.MACRO ITEM price, factor, units, quantity, mask IF factor < 0 s = 1 << 7 ELSE s = 0 ENDIF IF units = 't' u = 0 ELIF units = 'k' u = 1 << 5 ELSE u = 1 << 6 ENDIF e = ABS(factor) EQUB price EQUB s + u + e EQUB quantity EQUB mask ENDMACROName: ITEM [Show more] Type: Macro Category: Market Summary: Macro definition for the market prices table Deep dive: Market item prices and availability

Arguments: cycles The number of cycles to subtract from the cycle countMACRO FILL_MEMORY byte_count FOR I%, 1, byte_count STA (clearAddress),Y ; Write A to the Y-th byte of clearAddress(1 0) INY ; Increment the index in Y ; Repeat the above code so that we run it byte_count ; times, so write a total of byte_count bytes into ; memory NEXT ENDMACROName: FILL_MEMORY [Show more] Type: Macro Category: Drawing the screen Summary: Fill memory with the specified number of bytesContext: See this macro on its own page References: This macro is used as follows: * ClearMemory uses FILL_MEMORY * FillMemory uses FILL_MEMORY * FillMemory32Bytes uses FILL_MEMORY
The following macro is used to fill a block of memory with the same value: FILL_MEMORY byte_count It writes the value A into byte_count bytes, starting at the Y-th byte of the memory block at address clearAddress(1 0). It also updates the index in Y to point to the byte after the block that is filled.
