Title: 15 bit modes in picasso96 how?
Post by: Motormouth on May 04, 2018, 04:31:00 AM

I know this sounds like a silly question, but I cannot seem to get any 15 bit modes with voodoo cards in the mediator.

When I attempt to use the picasso II and the CVision3d they just show up with when you adjust and make hi-color modes in picasso96modes (I get both the 16-bit and 15-bit modes)

With the voodoos in the mediator alll I get to show up are the 16 bit ones?  Suggestions?  note:  I get the chunky 8 bit, the true color, and alpha modes to come up.

Does it help if you make file 'ENVARC:Picasso96/ShowModes' which contains text 'All' and reboot?

Voodoo does not support 15 bit modes.

@Thomas   Oddly enough I agree with you.

Maybe I asked the wrong question.  Some Warp3D games want the video mode in 15-bits and people do get them to work with voodoo, so how?

Maybe they are promoting the video to 16-bits?  like Nightlong
So how do you then promote to 16-bits?

Don't have my Amiga with me and can't really remember if I ever used 15bit on my voodoo.
A great utility though is this where you can force some screenmodes to test.

Nightlong can be promoted to 16-bit via Modepro or a similar utility.

Other 15bpp programs don't work if they query the list of available screenmodes and just quit if they don't find a 15bpp mode.  Somebody write this program to tell the system that 15bpp modes are available and just point to the same endian 16bpp mode.
