Re: Installing GS RAM card in slots 1-7




Yes, there isn't much RAM on the FPGA itself and in fact when I added the 1KB for mousetext characters it used up what was left :-(


There is no "ROM" but the block RAM inside the FPGA can be initialized from the serial EEPROM along with the rest of the configuration. This BRAM is also dual-port which makes it very convenient for a lot of things. If I don't use most of it in the design, I'm not getting my money's worth :) However in this case it would be relatively easy to move some stuff from the BRAM to external SRAM. Or initialize parts of SRAM by software either from the EEPROM or even from the MMC/SD card and use as ROM.

The CB design is pretty flexible so that almost anything could be done.
