These are essentially 2 screens with over-scan interlaced together.
Low resolution files are 416x273 pixels:
16 words palette
56784 bytes screen 1
56784 bytes screen 2
-----------
113600 bytes total
Medium resolution files are 832x273 pixels:
4 words palette
56784 bytes screen 1
56784 bytes screen 2
24 bytes padding if present, otherwise total size is 113576 bytes
-----------
113600 bytes total
Both screens use the same palette, but when viewed the human eye merges the two
alternating images into one.
