| Prefix | Example | Command String Format | Pointer After Command is Generated |
G3B_ |
G3B_Vtx(), G3B_LoadMtx43() |
Uncompressed | Set pointer ahead |
G3C_ |
G3C_Vtx(), G3C_LoadMtx43() |
Compressed | Set pointer ahead |
G3BS_ |
G3BS_Vtx(), G3BS_LoadMtx43() |
Uncompressed | Do not set pointer ahead |
G3CS_ |
G3CS_Vtx(), G3CS_LoadMtx43() |
Compressed | Do not set pointer ahead |
| Prefix | Example |

G3_Vtx(), G3_LoadMtx43() |
There are four formats for one function for API to generate a display list as shown in the table above. They are distinguished by prefixes. They correspond to four types of situations to generate a display list.
This corresponds to display list formats supported by Nitro hardware. Normally, it is advantageous to use compressed format.
| Uncompressed format | Wastes memory. Processor’s generate process is fast. |
| Compressed format | Does not waste memory. |
In comparison, the generate process is slow. However, as memory access is minimal, it could be fast overall.
When generating the command list, keep the current output buffer pointer using the DLInfo structure. This corresponds to whether or not to move this pointer forward to the next output position aftercommand output. Use it according to the rewriting situation.
| Set pointer ahead | Suitable for generating command list successively |
| Not set pointer ahead | Suitable for rewriting a part of command list after it is generated. |
