...16bit to 15bit textures?
I''m porting the SNES Emulator Zsnes to use OpenGL Instead of DDraw, and got some problems with certain adapters (Mostly old and 3DFX) and found out that it''s the 5_6_5 texture/pixelformat..
My question is now; How do I, easily, convert the 16bit texture to a 15bit texture? and does all GFX Adapters support 15bit Textures?
There seems to be different; almost no cards; except nVidia and ATI seems to work with 5_6_5 format (OpenGL 1.2.2 Compliant Drivers?) and as far as I has understood it; 3DFX Based card uses 5_6_5_1 (Alpha set to Zero) so actual; 16bit is 15bit on the earlier 3DFX''s
