Conversation

You know what? Why not touch all the namcos21_* in a single PR, should get things moving more swiftly |

What do you mean? |
Eventually I would need to cleanup the others namcos21*.cpp source files aswell. So I thought why not do it in a single PR? |

There are a lot of changes here, but I’m not sure on the quality of it.
On just a quick read of the code, I noticed you’d broken a fairly simple bubble sort of three items. There may be other stuff that’s broken that I haven’t noticed.
You haven’t been particularly consistent with reformatting. There are some if statements that you’ve reformatted to if (condition) style, while others where you’ve changed the line still use if( condition ) or other styles. Similarly, you’ve added spaces around binary operators in some places but not others.
A lot of the places you’ve added blank lines aren’t separating logical blocks of code, and hence don’t aid readability.

You’ve broken this – consider what happens if you get (3 2 1). The first swap makes it (3 1 2), and the second swap makes it (1 3 2). You need three comparisons to bubble sort three items.

Did you really proof read it? There are three comparisons.
