Thank you, it's good to know about "V" indication.
Yes, dont worry, I will use voltage translation.

Yeah, thats correct, but if you want the SNES to see all the 1024Kbits of the FRAM, the mapper need to be updated to address the rest of the chip address space. As almost no games use more than 256Kbit, I supose that you want to create some bank switching scheme for multcarts right? If thats the case, then connecting A13 and A14 as you said will work.Kayumba wrote: ↑Wed May 26, 2021 2:55 pm Hi soniccd123,
I would like to use 1024 Kbit FRAM like FM28V100 or CY62128EV30LL vs 256Kbit.
FM18W08 : pin 1 (A14) and pin 26 (A13) have different connections for LoROM and HiROM.
pin 1 :
LoROM cart 39 = A14
HiROM cart 42 = A17
pin 26 :
LoRom cart 38 = A13
HiROM cart 41 = A16
Should I do the same with 1024 Kbit FRAM for A13 and A14 address pins ?
Thank you
There’s only 1 game that uses more than 256k sram, at least on the standard non-special chip carts.As almost no games use more than 256Kbit, I supose that you want to create some bank switching scheme for multcarts right? If thats the case, then connecting A13 and A14 as you said will work.
Yes it’s for Multirom rom.soniccd123 wrote: ↑Wed May 26, 2021 5:21 pm

Hi, soniccd123, have you tried testing Aladdin? My game hangs. Are there any nuances?soniccd123 wrote: ↑Wed May 26, 2021 5:21 pmYeah, thats correct, but if you want the SNES to see all the 1024Kbits of the FRAM, the mapper need to be updated to address the rest of the chip address space.
