Hi, I've succesfully upgraded my 1Chip MSX with the latest HRA/KdL pack. What does exactly means "Added Mega-RAM SCC+(1MB) to SLOT1 when DIP-SW3=ON" in the history file of the upgrade pack ? Can I use execrom to load roms into that "virtual" megaram or is it just an SCC+ cartridge to be used in games ? I have tried and execrom does not work.

On the other hand, the 512 Kb ESE-RAM works fine but the configuration by means of DIP switches is a very akward procedure that can result in damage of the DIP sw's. It would be nice to be able to cycle the type of rom mapper by means of a key sequence or something like that. What do you think about this ?

mouser:

using my OCM-PLD v2.2b only:

SHIFT+F12 -> to change SLOT1 configuration on the fly
SHIFT+Scroll Lock -> to change SLOT2 configuration on the fly

MSXDOS2 commands are: MGLOAD.COM, SCROM.COM, ROMLOAD.COM only
