camcamcs Changed and populated the one table. A few major fixes too. Adjusted wording in general, wording for notes that indicate a need for further investigation, and placeholder image notes. |

| First, it is required to set the size of the ROM. Find the game on the [[https://datomatic.no-intro.org/index.php?page=search&op=datset&s=15&sel_s=15&text=&where=1&button=Search|No-Intro DAT-o-MATIC list of dumped Virtual Boy cartridges]], check the Size (in bytes), refer to the table below, and send the corresponding ROM Size Command. The commands follow the format <SFS_XX>, where “XX” is an exponent: ROM Size (bytes) = 2 ^ XX. (XX can be 24, 27, or 28, and possibly other sizes. Editor's note: document this.) | First, it is required to set the size of the ROM.

| * In case you don’t know or can't determine the ROM size of your cartridge, you can set it to the maximum size using the command <SFS_28>. This is equivalent to 256 MB. Note that no old retail cartridges exceed 32 MB, so the command <SFS_25> should work. (Editor's note: I have unfortunately not tested this functionality. -CS) | * If you don't know or can't determine the ROM size of a cartridge, it is recommended to try <SFS_24>. This command is for a size of 4 MB (16 Megabits), which was the largest ROM size of any retail title. Alternatively try <SFS_28> for a size of 32 MB (256 Megabits), which is the size of the largest documented flash cart. |

| * Note: if the size is set incorrectly, undocumented behavior can occur. If the size is too small, it will cut off the ROM data too early. If the size is too large, the data will start repeating. If you don’t know the correct size, and you set it to the wrong ROM size, you will just require the Overdump to be trimmed. This can be done in a hex editor like HxD, and/or with the help of a community member. | * Note: if the size is set incorrectly, undocumented behavior can occur.
