SRAM saves: Invalid external RAM start address

[garrettjwilke]

I am building a project with SGDK. there is a rom_header.c with the start address for SRAM. it is by default set as this:

0x00200000

when i load the rom with clownmdemu, i get this error in the console:

ERROR: Invalid external RAM start address - should be 0x200001, but was 0x200000

i am unsure if the address is incorrect in the rom_header.c or not.

saving "works" but when i reload my rom, the save data is not loaded.

i am also a noob, so maybe i am doing something wrong in my code.

The SGDK header does appear to be incorrect: it declares odd-byte-only SRAM, but then starts it at an even address. Commercial games do not do this: they start SRAM at 0x200001 instead of 0x200000.

This emulator could be made more tolerant of off-by-one errors like this, so I will add that to the to-do list.
