Fixing 63-bit rotates in main 68k. Fixing shifts by more than 31 bits in main 68k. Synchronizing the improvements main 68k had over stock StarScream to sub68k.

Configurable paths

2

There should be a way to specify per-project starting directories for picking art/mappings/DPLC/palettes. As is, if you start Flex from explorer, the dialog boxes always default to Flex' directory, making...

Add ability to cycle through sprite pieces

2

In SonMapEd, you can cycle through the individual sprite pieces of a sprite frame by pressing `shift+[` or `shift+]`. Having the ability to do similar in Flex would be great,...

Uneven scaling of sprites

1

The sprite strip on the left side uses a different scaling value for each sprite frame. There should be an option to have them all use the same scale, and...

Add ability to add global palette offset for objects

1

Some objects (example: Rexon badnik in Hill Top Zone in Sonic 2) use the foreground or background palette lines (lines 2/3). These palette offsets are coded into the game, so...

Some objects need the ability to load multiple art files, or have a range of blank tiles added before or after the art, similar to what is done for palettes....

Out-of-bounds memory access

Maybe it would be a good idea to have an embedded DSL for describing file formats, and have the internal code be mostly generated automatically. Something like (straw syntax): ```c++...

Add support for Kid Chameleon compression

Seems to be one more LZSS format.

Need to add multi-stream LZSS, with separate streams for descriptors and inline data. This is needed for #24, and relevant for #8.
