SRAM doesn't work
« Thread Started on Oct 19, 2009, 8:11am »
Strings works but longs gives you an assembler error and integers crashes the rom with an 'Adress Error'. Also, the saveram example doesn't save anything.

Maybe you didn't set correctly the SRAM support. Maybe if you post how you are trying to access to the SRAM we can help you.

I'm copying the code from the SRAM example, but using ReadP/WriteP instead of those old writing commands.

If you aren't using a custom cart you built yourself, you're using an MD-Pro or a Neo Myth. Both use the SSF2 rules for accessing SRAM:

store a byte of 0x01 to 0xA130F1 to enable SRAM as writable
store a byte of 0x02 to 0xA130F1 to disable SRAM
store a byte of 0x03 to 0xA130F1 to enable SRAM as write protected (read-only)

Once the SRAM is enabled, you read/write the ODD bytes between 0x200001 to 0x20FFFF.
