I recently was re-reading Fire In the Sky, by Eric Bergerud. In it, he mentions that the Zero's cannon were originally license built MG-FFs. If they were slower firing than the German models, he doesn't say, but the LW moved exclusively to MG151/20s pretty quickly when it became possible. I seem to recall from possibly other sources that later 20mm cannon models the Japanese used were literally scaled up Browning designs, identical to the US M2, just bigger. I recall that the display at the National Air & Space Museum in Washington DC certainly reflected this.
In any event, the Japanese had issues with their cannon having very different ballistics and trajectory from their light machine guns, and found that the cannon were less effective in their favored close-in maneuvering combat; it seems that the cannon rounds often went somewhere different from the MG rounds if you fired during high-G turns (they were slower firing and <probably> started firing a fraction of a second later than the MGs).

So you're actually talking about two weapons there
The Type 99 used by the Japanese Navy is derived from the Oerlikon FF of which the MG-FF is also derived. So they share a similar parentage but with some unique attributes of their own. The biggest difference here is that the Germans used the Mine shell ammunition whereas I don't think the Japanese did... using AP and HE rounds in some sort of combination.
The Browning .50cal scaled up into a cannon is the Japanese Army Ho-5 20mm cannon which was probably the best of the Japanese cannons used in the war. This cannon is actually modelled in IL-2. How well I'm not sure... but it is present in the game files. You'll find it on the Ki-84 and Ki-100.
The Japanese Army and Navy were highly independent structures sharing very little in the way of aircraft and aircraft armaments so there is a huge long list of machine guns and cannons... of which very few are represented in any capacity in IL-2 1946. There is even a variety of different guns used in IL-2 1946 that were chosen to represent the missing guns... the same gun is represented by the MG17 in the nose of the Zero and the Vickers K in the nose of the D3A Val and the Browning .30 in the nose of the Ki-27 and Ki-43. It's a mess!
