I've already programmed the tgx16 and I've had some difficulties with the graphical mode soon I tried to display a picture larger than 16 colors ...

Thank you for explanation.

It's essentially the same concept. On the TurboGrafx-16, each 8x8-pixel space can use one of sixteen 15-color palettes. A 4bpp background on Super NES has half that (eight palettes).

The common problem between the TGX16 and SNES is the lack of tools or maybe to know how to use it in my case.

For example, I use GFX2SNES (based on pcx2snes) and SIXPACK for converting image. My problem is how to generate a 16 pictures colors with a 256 colors palette.

I succeed to display the bg1. I can look the bg2 behind the bg1's transparency, but seems to have a palette issue since there is no color on it.


Edit : After watching into no$sns debugger, the BG2's details indicated palette 0 for the whole second layer pixels.

Maybe the PPP bits used for the second 16 colors tiles map are not set don't you think?
