Due to lack of experience with gnu tools and lack of VS2005 project for latest mame. I decided to use old vcmame 0.105.
However I am not getting collect colors.
Here's a screen of midres.zip (Midnight Resistance)
NOTE: im using old Mame 0.105 version
To retrieve the game texture I inserted a callback inside
>> mame0105\src\windows\window.c
>> void win_update_video_window(mame_bitmap *bitmap, const rectangle *bounds, void *vector_dirty_pixels)
A memcpy is performed for copying texture data
-I tried both d3d and ddraw in mame
-I tried both formats in Ogre3d
PF_R5G6B5 16-bit pixel format, 5 bits red, 6 bits green, 5 bits blue.
PF_B5G6R5 16-bit pixel format, 5 bits red, 6 bits green, 5 bits blue
-A also see some big random blocks in rendered image not in original game.
But no difference. What possibly is wrong?

Keep in mind that MAME outputs different pixel formats per game. It can be 15-bit 0-5-5-5, 16-bit 5-6-5, or 24-bit 8-8-8. I gather from your screenshot that you're trying to consume MAME's 5-5-5 as 5-6-5. And if none of this makes sense to you, back away from what you're doing now.
