Describe the issue.
The Bahamut Lagoon English Translation by Near is proably the only Cart that has ExHirom and 256KBit SRAM. When trying to read the Save, I only get the first Bank (0xB0) and the rest ist filled with 0xFF. Trying to Test the SRAM results in ERROR on 0x00 and OK on 0xFF. Turns out the "romtype == EX" routines are missing the "// Large Sram Fix" the "HI" and "LO" romtypes have. The function stays in the same bank (0xB0) and tries to read the whole 256KBits from the same bank, resulting in "FF" when going over 64KBits. I copied and pasted the "// Large Sram Fix" to the "EX" part (marking it "// Large EX Sram fix). I attached the modified SNES.ino for you. BTW: Since the reader read "FF" on error it would be better to Test the SRAM with "0x0F" and "0xF0" instead of "0x00" and "0xFF". Regards, John P.S.: the "romtype == SA" section is also missing the large sram fix...
