Dreamcast Saves

[crusadeRGP]

In my collection there are several ways to load a game that are setup using different emulators for test or different settings applied. My issue is the only system I can't share the game saves between emulators is Dreamcast Visual Memory Units when using per games saves. Each emulator or RetroArch core seems to use a different naming conventions. Aqua GT for example: 

T40509D_50.A1.bin 

T40509D_50_vmu_save_A1.bin 

Aqua GT (Europe).A1.bin

Is there any know way so no matter which emulator I use it will use one common game save file? I've tried using a shared single VMU for all games but it only contains 200 blocks which fills up quickly.
