Summary	08899: exzisusa, exzisust: Greenish hue is present when it should not be
Description	This only applies to the Japanese conversion kit version (exzisusa) and the TAD license version (exzisust). Upon loading either version, there appears to be a greenish hue which makes the color palette different from the proper color palette on the Japanese dedicated version (exzisus). This could be due to a bad dump of one common ROM ("b23-03.14l") in their ROM sets. A real hardware gameplay video (albeit a low-resolution one) of the TAD license version shows the proper color palette without the greenish hue.
Steps To Reproduce	1. Load either version of Exzisus (exzisusa or exzisust). 2. You can see that the greenish hue appears when it should not, unlike the parent system (exzisus).
Additional Information	The screenshots below use the title screen as an example. The "Verified with Original" flag has been checked due to the report including a video of the TAD license version being played on real hardware.
