There are some bugs when exporting *metasprite banks* VS *individual metasprite* to clipboard. When exporting individual metasprites, negative values are prefixed with a low byte operator, but it's not the case when exporting banks.

Front:
  .byte <- 8,<- 8,$00,0
  .byte    0,<- 8,$01,0
  .byte <- 8,   0,$10,0
  .byte    0,   0,$10,0|OAM_FLIP_H
  .byte $80

VS

Front:
   .byte - 8, - 8,$00,0
   .byte   0, - 8,$01,0
   .byte - 8,   0,$10,0
   .byte   0,   0,$10,0|OAM_FLIP_H
   .byte $80

This results in Error: Range error (-8 not in [0..255])

Also, when exporting individual sprites, animation data are not included. They are included when exporting banks, however the value often overflows. We get things like .byte 300.

For instance, with this Metasprite GnomeStillFront, I get .byte 300 as animation data.
