Hey everyone! I''m currently working on an alpha blending library in c++ with inline asm, called vbDABL. It''s for use in vb primarily, because it''s pretty much impossible to do alpha blending at an acceptable speed in vb w/ dx7 without using direct3d. I''ve released a public beta at http://www.daedalusd.com/vbgaming/files/vbDABL010.zip . It''s open source as well! But, my problem is that I don''t have a video card that uses 565-mode. On those cards, it seems that the ''colorblend'' functions, whether you use the 565 or 555 mode functions, crash the application HARD. But, it works fine on 555-mode cards, even the 565-mode functions which just create wacky colors but still don''t crash it. Would someone be willing to take a look for me and see what''s wrong, even if you don''t solve it, I''d appreciate any help/suggestions Thanks! David
