Restoring saves doesn't work

[jzobac]

Hi, when trying to restore saves (seems that backup works) i get only "timeouts".

configuration rpi 3, Zelda handheld, 64MB flash from Farnell (4MB original patched fw, 60MB retrogo)

Same problem here - with the original 4MB Zelda flash chip.

Make sure to set the correct environment variables when you restore the save games, just like you do when you run make flash.

It's likely you have not set e.g. INTFLASH_BANK=2.

I just did a full test of a clean Zelda unit with 64MB flash and an ST-Link, and it works.

My commands:

export ADAPTER=stlink
export GNW_TARGET=zelda
export EXTFLASH_SIZE_MB=60
export EXTFLASH_OFFSET=4194304
export INTFLASH_BANK=2

# From game-and-watch-patch:
make PATCH_PARAMS="--device=zelda" flash_patched

# From game-and-watch-retro-go:
make -j8 flash

# Play some games, then backup saves
make flash_saves_backup

# Save some new state to know that you have a different save locally vs on the device

# Restore locally stored saves
make flash_saves_restore

# Verify on the device

Yes, works! Thank you.
