Not An Issue - Just Requesting Help On Using MMU For Allowing "Full Ram" Mode On Spectrum NEXT. about sjasmplus HOT 2 CLOSED

No worries - I finally figured it out. It turned out I was launching the .nex file with the wrong parameters.

All working now.

Glad you worked it out. (I didn't check details of your zip file, and now I will skip if you resolved it).

Feel free to reopen or post new question, if you stumble on something else.

Some usage of MMU is described in the first chapter of "SpecBong" tutorial: https://github.com/ped7g/SpecBong/wiki

The all-ram mode is possible with Next just by using its regular MMU next-registers $50..$57, but keep in mind the default layout when new NEX file is loaded has ROM in bottom 16ki, so you must have initial setup code elsewhere, and bank RAM pages as you want them in code. But you can layout all of that in sjasmplus IMHO easily, that's the whole purpose of MMU directive and $$label operator.
