I now understand exactly how vertical guardians behave in MM
versus JSW (and will attempt to modify my conversion-algorithm to
accommodate the differences), but this warrants a message of its

Try not!
Do, or do not.
There is no try.

if (velocity < 0) {
top+= (startPos - top) % velocity;
bottom-= (bottom - top) % velocity;
} else {
bottom-= (bottom - startPos) % velocity;
top+= (bottom - top) % velocity;
}
if (bottom == _memoryMM.peekU(radm+v+6)) {
bottom-= velocity >= 0 ? velocity : (byte)-velocity;
}
while (startPos > bottom) {
if (velocity >= 0) velocity= (byte)-velocity;
startPos+= velocity;
}
if (startPos >= bottom && velocity >= 0) {
velocity= (byte)-velocity;
}
while (startPos < top) {
if (velocity < 0) velocity= (byte)-velocity;
startPos+= velocity;
}
if (startPos <= top && velocity < 0) {
velocity= (byte)-velocity;
}
