You should have an option to use the controller upsidedown. Operating the Intellivision disc one-handed is easier that way.
There is no such thing as JLP bank switching. JLP cartridges use Mattel ECS page switching for larger roms. JLP support is required if your program uses JLP hadware acceleration. How large is the rom file?
You are absolutely right, in which ”JLP bankswitching” is in fact Mattel-style bankswitching.
The term is being used loosely here to facilitate buyer understanding of the environment required to run the game.
The rom is large enough not to fit a regular cart. The game does also use math acceleration.
Never tried the upside down controller approach. Will check it out! Thanks
