Palette corruption help
Posted: Wed Mar 06, 2019 1:23 pm
Hi Guys!
Another noob question
Its my understanding that we are limited to 4 color palettes?
For some reason, Im loading different PNG's as backgrounds (TMSS, intro screen, title screen, first animation)
however when loading my foreground on PLANA and BG on PLANB, my FG seems to load perfectly however my BG sees a lot of corruption mainly in the top 8 rows?
The bottom is pulled from Photoshop, it is correctly indexed yet causes some weird garbled mess
Anyone see what I'm doing wrong, Im getting ready to load all the sprites etc after this but cannot figure this one out?
its almost like there is something tampering with the image as the bottom of it seems okay?
[EDIT] here it is with correct transparency added to FG, that eliminates the white issue but still have the strange garbled mess
Cheers!
