How to view backgrounds and tilesets in Mednaffe

3) navigate with the arrow keys: up and down for scrolling, left and right to change between backgrounds and sprites
4) , and . are used to change palettes
Backgrounds & Sprites


Unfortunately, the bg colour of the tile viewer eats the black outlines of the sprites. Solution: Wrong-Colour-Method

With this, you get the outlines of the sprites. Of course, you need to recolour the sprites afterwards.
Disabling / enabling layers:
CTRL+1, CTRL+2, CTRL+3, etc. maybe if you have a different keyboard, it's called STRG+1, STRG+2, etc.

The shadow is a nuisance, a combination of tile ripping and screenshots is maybe useful.
About quicksaves:
Select quicksave slot with 0-9
Make quicksave with F5
Load quicksave with F7
The ones above are the most important, if you want to know more about controls, Global Settings - Key Assignments in Mednaffe and the official documentation here give you more to read:
