Returns within the command main routine (return, jump return, skip return) are prohibited.
Zoom point values are only 0H, 5H, 6H, 7H, 9H, AH (10), BH (11), DH (13), EH (14), and FH (15). Any other setting is prohibited.
When HSS = 1, the end code of the original picture is ignored regardless of whether the sprite is enlarged or reduced.
Set the lower 2 bits of CMDLINK to 00.
Set the lower 2 bits of the lookup table to 00.
When setting the color bank, set 0000 to the lower 4 bits of the color bank data.
Set to ECD = 1, SPD = 1, and color mode = 0 when non-texture.
When performing color calculation with non-texture, set RGB data (8000H or higher) for non-texture color.
If you set to RGB mode and use 7FFFH data for the original picture, set ECD = 0.
When using RGB mode and using 0000H data for the original picture, set SPD = 0.
When the RGB mode is set, setting the frame buffer to 8 bits / pixel is prohibited. The only color modes that allow 8 bits / pixel are modes 0, 1, 2, 3, and 4.
When the frame buffer is set to 8 bits / pixel, set the color calculation mode to 0. Only replacement is possible. Other color operations are prohibited.
When the frame buffer is set to 8 bits / pixel, the upper 8 bits of the non-texture color are ignored. At this time, the use of RGB data is prohibited.
Do not set the MSB on bit (MON) to 1 when the frame buffer is set to 8 bits / pixel.
When the MSB on bit (MON) is set to 1, set the color calculation mode to 0.
Store the command table at 000000H address of VRAM.
