Hellow, Dr.neo. Thanks a lot for the answer.
I still a little confused about the save feature in the SD card... Normally, saves are stored inside the DUO or, in the case of a stock PC-Engine, using a device like the Interface Unit, Turbo Booster Plus, Ten no Koe 2, Backup Booster 1 & 2, or Shuttle Backup Unit.
So, using the NEO Power PC-E 128M+SAVE Super Flash Cart to load ROMs, the save files will be stored inside the flash cart instead of the system's memory, correct? If yes, so the flash cart will create saves with no need of an adicional device, who is interesting. But if a storage device is present, who will have priority to store/access the save files? And more: There's some way to copy saves between the system's memory and the flash cart to backup the saves?
And about the saves to upload... If you can fix your PCE, can you offer the save files for download, or ask someone who can do it? I'm just curious to check the file's contents...
Thanks for your attention. I'm waiting for your answer...
