Hi guys, I'm experiencing a problem with a VG8235. I got it, seems to be new, but when I put inside a carnnivore 2 card or an sd mapper cartridges, everything works fine except the ram expansion. I should read 640k ram but it remain on 128k and roms or games doesn't works due the missed ram. Any help about? Thanks

Don’t worry, the message 128kB RAM is hardcoded Wink in Nextor you can type MEM and you will see the 1MB in the Carnivore2 is active.

it's normal the VG8235 does not display the ram count
use testram or other program to check if the ram of the cartridge is taken into account
