Item collection sound

[Spider]

Following from the topic over at Spectrum Computing here about small game changes, here's a rough/ready patch for Manic Miner:

Software Projects version:

mm_item_sound_SP.tap

 

Bug-Byte version:

mm_item_sound_BB.tap

 

As these sit in the 'empty space' area's , its quite possible they could malfunction with third party games however in general there's plenty of space to change the new CALL instruction at 36752 (SP) 36741 (BB) to go somewhere else to make the sound.

Needless to say, applying the code against the wrong engine will likely have undesired effects.

Code updated slightly. Then reverted as the original was correct (the fixed one did not add any points!) and two basic checks added , one to confirm the game code is present and one to perform a basic check that the correct version is present

That was always a big drawback to me with MM... Not hearing that little "kiss" sound when you get an item. There's nothing like throwing yourself onto a pile of items and hearing that noise 10 times in a row : )))

You're welcome. Some third party versions do this although if I recall they are all based on the Bug-Byte version. My work above is not far off a copy of that.

Will rewrite this as a simple assembly routine. I did think about having one Basic one to detect which version but I'd already done the very quick ones above at a request.

The assembly will simply detect the version, apply the code and exit as I see it anyway.
