@amadvance This will be the last of these bootlegs BTW it might have some gfx niggles depending
on if your 106 Genesis video code can handle the different palette handling this game requires.

The pics at the top of the thread will show the issue with the water level gfx which might also
be an issue in this core but fingers crossed it wont be.....
libretro/mame2003-plus-libretro#1870

How are things with these bootlegs do they all work.?? im assuming they do otherwise you would
have told me, anyhow the code compiled clean any build failures will just be the usual due to me
prefering single commits feel free to merge.

They are fine. I don't try them extensively, but for what I see they work!
