Currently working at some ST-V bitmap issues,at the moment for fixing the backgrounds/foregronds in Virtual Mahjong 2 – My Fair Lady…

…which is annoying as hell because it’s using a mix between the zooming,the window system and I dunno which else (translated: the black on the snap are the requirements needed to fill with).
Once that this is done I would like to fix at least these other two bugs:

Elan Doree 4bpp “presents” msg at attract mode

Pro Mahjong Kiwame S flames on title screen

Edit: first game fixed (the remaining black is probably caused by an imperfect visible area):

Edit 2: second game fixed (caused by a wrong implementation of the window effects):

edit 3: found why this is giving bad colors,it is a mix between missing alpha blending effect and a (possible) SH-2 core bug:
