I’ve added a 16KB RAM expansion to the MiST port of the Apple II+. It’s seen as a language card in slot 0.
I’m also working on a Saturn 128KB RAM expansion but it’s not working yet and need some more work.
To implement both I made use of some manuals available on the net which show the control codes for those cards which need to be implemented in the hardware.
I’ve uploaded a new binary with 8kb more RAM (28kb in total) and cartridge multipart support.
To run multipart crt’s turn on “CRT with load address:yes” and load the lower part first.
Use the Tosec crt’s without the “[a]” in the name because we need the load address. Load the $4000 or $6000 part first and then the $A000 part. The $A000 crt will trigger a reset and starts the game.
