MisTer SDRAM (XS-D) v2.5 board 128MB

This Extra Slim (XS-D) v2.5 board provides 128MB of SDR SDRAM memory for cores requiring a large (>512KB) of memory including the Neo Geo core. Although the DE10-Nano has built in DDR3 RAM, it has a high latency and is not suitable for the timings required of retro EDO DRAM. So if a core requires precise memory timings, then the onboard DDR3 cannot be used.Every one of my boards uses the high quality Alliance memory paired 。You can be confident knowing each 128MB SDRAM Extra Slim (XS-D) v2.5 board has been tested for over an hour at 140 MHz . I have also tested each with the Neo Geo console core, Acorn Archimedes (Archie) core, Game Boy Advance core, Sega Mega CD core and in Neo Geo games which require a 128MB module to play this ensures no issues are present.
