MiSTer FPGA Forum

For posterity: It was indeed the missing SDRAM that caused the issue; I ordered it and then everything started working so great that I forgot to follow up here!

Thanks for the input, gang.

New MiSTER without SDRAM board here

When I load any ROM in the SMS core, it only shows the Sega logo and doesn't progress to the game. Is there some step I'm missing?

Other cores that don't require SDRAM are working properly (Genesis, GBA, etc.)

Core: SMS_20200602.rbf

Thanks
