It has been a while since I used WinUAE, but you should be able to remap the keys in the "Input" settings.
Yes that was the input settings. I am in the learning curve right now! The DOS box key mapping with the GUI is the easiest. Normally if Numpad2 were to represent left , I had to map the left key with Numpad2 which originally performed the left function. But WINUAE I think wants the user to map the action itself. Also I wonder why the configuration is not saved and seems reverted on closing and opening.Not sure learning....
Amiga emulation is so complex we are lucky to have it as low as this! There are ways to reduce CPU load, but always at the expense of emulation quality.
Could you brief the method.
The audio setting for that sort of thing will be in the actual game options, not the emulator.
Since mp3s did not exist in the early 90's the likelihood is that the music is what is known as a MOD, which will be sharing the 4 amiga audio channels with the sound effects... Sometimes that means stealing time away from the sfx...
Yes that very insisting BGM is a little overpowering the SFX.
On general terms , WINUAE though has adapted the mouse and touch keypads into the mapping options (which surely would not have been an option in the original past?) , surprisingly wants the user to go thru the cumbersome eject and load floppy, rather than control it thru a switch.
