Fix/Improve Subor Mouse

[DevanWolf]

Currently, when using the Mouse on the Educational Computer 2000 rom, moving the mouse only moves the cursor 1 pixel per frame (up/down/start/select only). The mouse needs to use the (Right/Left) inputs to make the mouse move how many pixels up/down/left/right.
Here is what the mouse should work when the cursor fully moves, taken on a real Dendy console, though.

Interesting, I have never used this feature. Do you have any other examples of roms that would use the Subor mouse?
