I have one of the new SX-1 FPGA and my question is specific to this device. I'm pretty new to this, so I'm not sure if it has a memory mapper or MegaROM app built in or if it's just because it is an MSX2+ core, but it can load 128k ROMs through SofaRun with SofaROM with MSX-DOS2 from the SD card. However, I have a few larger ROMs (256k and 512k) and I am wondering if there is a way for the SX-1 to play these ROMs natively with added software on the sd card, preferably through SofaRun or something else that lets you browse files, without using an extra cart. Full disclosure: I have really only used BlueMSX and RetroPie for MSX before last week. From what I know at this point, things on the level of, for instance, NESTOR are over my head right now with all the terminology.
Also, I'm thinking this may require some PITA installation like SymbOS, but is there something as good or better than SofaRun that shows long file names (more than 8 characters).
Thanks!
