DMOG DigiROM format

The DMOG DigiROM format is used to battle DMOG devices, and also serves as the modern V-Pets "Other" option. This battle system is also available in a lot of Digivices, such as the D-3, D-Power, D-Tector, and devices such as the Pendulum Cycle.

Practical example

Let's take the following DigiROM:V1-FC03-FD02.

The first step consists on converting the DigiROM into binary.

Packet number	Data
Packet 1	1111	1100	0000	0011
Packet 2	1111	1101	0000	0010

Packet number	Data
Packet 1	Boost mirror	Slot mirror	Boost	Slot
Packet 2	Version mirror	Outcome mirror	Version	Outcome

Meaning of each field

• Boost: Boost is how strong your Digimon is, based on the number of pills it has been given. The initial value is 0 but will increase to a maximum of 4 on the original Digital Monster (though the initial American models cap at 2, not 4). Each Digimon can only increase their boost by two levels, with each level increasing for every 8 pills given. The higher the boost, the more likely it is that your Digimon will win, though Slot has to be taken into account as well. HOWEVER, the boost for all modern devices using the “Other” Battle System will be 0, it is not possible to increase it. This gives original Digital Monsters a slight advantage over modern devices

• Slot: The original Digital Monster used a slot system to represent what Digimon was being used. This meant that no matter which Digital Monster you were using, two Digimon in the same slot were effectively the same Digimon. In other words, Greymon was basically the same Digimon as Kabuterimon, Unimon and other Digimon that occupied the same slot in the evolution charts, AKA Best Care from the top Child. The slots, as revealed in a Japanese Guidebook, are as follows:

	Slot	Version 1
A	Child 1	Agumon
B	Child 2	Betamon
C	Adult 1	Greymon
D	Adult 2	Tyranomon
E	Adult 3	Devimon
F	Adult 4	Meramon
G	Adult 5	Airdramon
H	Adult 6	Seadramon
I	Adult 7	Numemon
J	Perfect 1	Metal Greymon
K	Perfect 2	Mamemon
L	Perfect 3	Monzaemon

These slots then each have a specific interaction with one another, shown below. Each number is the chance, out of 16, that matchup will result in victory for your Digimon (represented by the slot number on the left)

Hex		3	4	5	6	7	8	9	A	B	C	D	E
	Slot	A	B	C	D	E	F	G	H	I	J	K	L
3	A	8	8	2	3	2	3	2	3	7	1	1	1
4	B	8	8	2	3	2	3	2	3	7	1	1	1
5	C	15	15	8	11	9	11	7	11	13	3	3	3
6	D	13	13	5	8	5	9	5	7	11	2	2	2
7	E	15	15	7	11	8	11	9	11	13	3	3	3
8	F	13	13	5	7	5	8	5	9	11	2	2	2
9	G	15	15	9	11	7	11	8	11	13	3	3	3
A	H	13	13	5	9	5	7	5	8	11	2	2	2
B	I	9	9	3	5	3	5	3	5	8	1	1	1
C	J	15	15	13	14	13	14	13	14	15	8	5	5
D	K	15	15	13	14	13	14	13	14	15	11	8	5
E	L	15	15	13	14	13	14	13	14	15	11	11	8

So to explain this chart, let’s look at our Agumon code. Its slot value is 0011, or 3 when represented in Hex. 3 would mean Agumon is Slot A. Now let’s say Agumon is fighting Seadramon, who is slot H. Using the above chart, we can see that matching A on the left with H on the top gives us a 3, meaning a 3 out of 16 chance of being able to win. This chance is affected by how much effort you have though, so always make sure to have the maximum effort you can!

• Version: This value will identify which specific version of a device series is being used. Each Battle System has its own range of version numbers, generally in sequence starting with the first released device.

• Outcome: Simply whether you win or lose the battle. The original battle system wasn’t very complex, so there’s no HP or anything, it’s just whoever fires the bigger shot at the end wins. 1 means victory while 2 means defeat.

• Mirrored values: All of these values are meaningless on their own, but are used by the device to ensure that a valid code is being sent. Simply put, each mirrored value just displays the opposite bits as the value it’s mirroring. So if we look at the slot for example, we see the value for Agumon is 0011. Mirroring in this case means flipping each bit, so it becomes 1100. Agumon’s value happens to also mirror if you were looking at it from back to front, but that won’t always be the case. If we look at its Outcome value of 0010 for example, the mirror would NOT be 0100, since we are flipping each bit. Instead, it is 1101.

Digimon Pendulum compatibility

The Digimon Pendulum uses a new battle system, BUT it is still compatible with the Digital Monster Battle System. The thing is though, people noticed that Pendulums almost always beat the originals for some reason. Well as many guessed, this was entirely intentional.

the Digimon Pendulum could not initiate battles with the Digital Monster, so the outcome is always decided by the Digital Monster since it sends its outcome packet first.

The Digimon Pendulum always sends 7 effort, and slot L. Remember earlier, I said the max for effort on a Digital Monster was 4? That’s right, the Digimon Pendulum uses 7 to ensure it is always going to have more effort than its opponent. Not only that, but its slot is the strongest possible, so Pendulums are basically unbeatable when using the Digital Monster Battle System! It doesn’t matter what Digimon is used either, as a Child will produce the same code as a Perfect, it will always have 7 effort and be slot L.
