**0 = ? (used by SCPS-18011 Um Jammer Lammy, and SLPS-01818 Langrisser IV & V Final Edition [Disc1of2])
In Um Jammer Lammy is used together with command 0x13, so it was a bit doubtful if it was a mistake. But Langrisser IV & V Final Edition [Disc1of2] uses it too and is the only command used by this disc, so it "should" do something. Um Jammer Lammy in netemu 3.40 was fixed only with command 0x0/0x0 (id/data)

*Um Jammer Lammy (SCPS-18011) uses somewhat new external config revision (11580) in official classic's external config, but only uses command 0x13. Keep in mind the game was released Febuary 27, 2008, so package was possibly updated with new config at some point, and then in internal table, so maybe it once had a different config command in config table and 0x00 nullified it. Langrisser IV (SLPS-01818) has old config revision (5713) and uses command 0x03 set to 0x3E8, so just default. Maybe internal config for Langrisser IV is empty config just to also nullify external config? --[[User:Mrjaredbeta|Mrjaredbeta]] ([[User talk:Mrjaredbeta|talk]]) 03:32, 1 September 2023 (CEST)

I'm not familiar with CELL floating point unit quirks, but value could be just single precision float from the start, why complicate that so much?<br>
