Problem with FVDI+NVDI vr_transfer_bits() #45

Open AtariTrek opened 1 year ago

AtariTrek commented 1 year ago

"fvdi + nvdi" works to some degree vr_transfer_bits() seems incomplete fvdi +nvdi crash at a null address to the screen with vr_transfer_bits()

And vs_ctab_entry() commands seem not fully supported, which makes fvdi uncomplete compared to nvdi.

Thank you.

@AtariTrek can you provide more details? I.e. how do you run fvdi and nvdi (auto, mint.cnf, what order, what machine) and some code snippet to test?

Hi Miro! The program imgview (an excellent program) crash when "fulling" the screen image while using fvdi. While using plain nvdi it doesn't. https://atari.gfabasic.net/ This is due to the fact that a NULL address with vr_transfer_bits() makes fvdi crash, while the nvdi docs clearly states that a Null address can be used. I hope this helps ;) Thank you

Ah ok, so it's "just" a plain fVDI bug. I was confused with the combination with NVDI.

AtariTrek commented 1 year ago

Well both yes and no. It is with the combination fvdi+nvdi that makes vr_transfer_bits() crash together with dither_bits thank you

Can you please test just fvdi alone then?

AtariTrek commented 1 year ago

Dither_bits does not exist with fvdi alone, it is needed with nvdi. If you install the program I provided (imgview+modules) you will be able to replicate the problem. The other modes perhaps does the same thing with vr_transfer_bits(), I am not sure. I use aranym windows and do not have fvdi installed at the moment. Just nvdi and blowup.

I have now installed fvdi, but it shouldn't matter for test purposes since I can not test vr_transfer_bits(/) without dithering and nvdi 5.03?

The problem would most surely be fvdi since the null adress works with nvdi only without problems.
