Yesterday I tried to run a game that constantly gives an EMS memory error as I show below:

"Could not grab system RAM for EMS (below 640K)"

I have tried everything, both activate and deactivate the EMS, XMS and UMB memory in the DOSBox SVN as well as try all possible configurations of the loadfix and memsize commands. However, I have not been able to solve it in any way.

This error does not allow me to play or even install the game, so I would be very grateful if anyone knows to find the solution to this problem.

Sounds like a case of EMM page mapping of conventional memory region.

You can try using JEMM from here to manage memory. Set xms=false, ems=false, umb=false in the conf, then run JEMM in DOSBox with the command: JEMMEX FRAME=E000 LOAD

It works! Thank you very much! 😊

Now the problem I have is that the load of each video sequence drops to 1 frame per second for half a minute, more or less, and the mouse pointer moves with lag. Was there any way to make it more fluid for one thing than the other?

Thanks in advance.
