Senran Kagura Estival Versus & Peach Beach Splash PS4/PC saves

[Niko of Death]

These two games have very similar save formats, so I thought it was appropriate to group them together.
Both have a header added on the PC saves, and a discrepancy in their static filesizes. For Estival Versus, the PS4 saves are a static 512KB, while the PC saves are a static 480KB. Meanwhile, for PBS, the PS4 saves are a static 768KB and the PC saves are a static 576KB. Due to the amount of padding in the saves, its difficult to tell where the PC saves are trimmed. Any help identifying the differences in the formats would be appreciated.
