Looking at Double Wings protection,first of all to fix the protection jump vectors in it.Protection works in a easier way than expected,to say in the simplest words I can use it’s a “fan type jump vectors” (i.e. only a few possible results are expected).

Made Filetto working by adding the proper device emulation:

Yesterday I’ve started to look at Balloon & Balloon (Eolith),it still doesn’t work due of Flash ROM emulation:

Notice that this is just a break from the ST-V driver,it is still that my first priority.

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:

I’m currently doing some major work to the jalmah.c driver,in order to fix most of the issues in it and in search of new protection issues.Some WIP shots:

Mahjong Kakumei

Mahjong Daireikai

Mahjong Channel Zoom-In

Urashima Mahjong

Finished for good the protection vectors in Double Dealer.Now I have to write the coin/credit simulation (which is handled by the MCU) and finish the video hardware,but the bigger part is actually done.

The “girl” snap is actually from the attract mode…
