Current space used by creature graphics PNG files in packs that would need separate TWBT versions:
Afro | 0.5 MB |
AutoReiv | 0 - uses same creature graphics for both TWBT and non-TWBT versions |
CLA | 0 - does not have a TWBT version, but creature graphics would be the same in both versions if it did |
DragonMaster | 0.6 MB |
DungeonSet | no non-TWBT version so doesn't need duplication, but if it did it would be 13.6 MB (2.8 MB compressed) |
GemSet | 0 - uses same creature graphics in both versions |
Ironhand | 0.7 MB |
Jolly Bastion | 0 - no creature graphics |
Mayday | 2.4 MB (1.3 MB compressed) |
Meph | no non-TWBT version, so doesn't need duplicate graphics |
Obisidian | 0.7 MB |
Phoebus | 0.5 MB |
Rally Ho! | 0.5 MB |
Spacefox | 0.7 MB |
Taffer | 0 - same creature graphics in both versions |
Tergel | 0 - same creature graphics in both versions |
Wanderlust | 0 - same creature graphics in both versions |
In total, the additional creature graphics with in the graphics packs above would make a pack up to 5 MB heavier with compression in Mayday. The TWBT-versions of the creature graphics PNG files are also likely to be a little lighter than the non-TWBT versions that include backgrounds. I just tested with an Ironhand tile sheet and the TWBT version was less than half the size.
Also, it might be worth mentioning that excluding the dwarf graphics, Phoebus, Obsidian, and Dragonmaster would share the creature graphics in TWBt version. And I think the Mayday creature graphics are pretty much a superset of those and contains a bunch of additional creature person graphics from Tallcastle.
