Wanted - any MSX1 program on cartridge that uses the mouse.

Music studio G7 can use keyboard , mouse and trackball

with ODO.COM you can run Music studio G7 in the memory

Searching for MSX1 mouse enabled software on real cartridge is pretty much looking for a needle in a hay stack. I bet there exists a software for almost each of your fingers, but buying one is another thing... Almost all mouse enabled software is disk software made for MSX2 & up. I think searching for Kralizek's Operation Wolf cartridge is your best bet but even that is not manufactured at the moment.

Just as a fair warning: Even if you manage to find one you are not exactly testing properly if your mouse actually works with MSX2 BIOS routine (that is by far the most common way to interact with mouse). Please note also that there are many ways to implement even such an utterly simple thing as mouse protocol. ie. MSX2-BIOS talks to mouse in a bit weird way as it also talks Trackball protocol from the same port, at a same time... (Just in case you have Trackball connected instead of mouse)

BTW you should try the "Trading & Collecting" section instead.
