[Coco] Coco3 under MESS and joysticks

[Mark McDougall]

Hi all,

I'm currently trying to sort out my joystick programming issues, and 
currently have one hand tied behind my back because I do not own a 
2-button joystick right now.

My development platform has always been MESS, and it appears to be 
causing me some confusion. Until today I was running under v0166, and 
today I downloaded v0172 to check out the source and it appears nothing 
has changed.

For starters, _both_ the input port definitions are labelled as "Button 
1" on the right and left joysticks respectively. This can be seen in the 
source and on the input mapping GUI. I would have expected "Button 1" 
and "Button 2".

Ordinarily I would put this down to a simple text labeling issue, but it 
seems there's more to it.

Tim's very handy PIA "cheat sheet" shows left joystick buttons going to 
PA1 & PA2, and right going to PA0 & PA3. If I'm reading the super-magic 
MESS macros correctly, then coco3.cpp would suggest PA1 & PA3 and PA0 & 
PA2 respectively. So which is correct?

Finally, to obfuscate matters further, _both_ Left Button 2 and Right 
Button 2 are generating a phantom <SPACE> keypress in MESS; IIUC only 
one or the other should be able to generate this (row 3) depending on 
which PIA connection is correct.

I'd be able to confirm this easily on real hardware except for the fact 
that I don't have a 2-button joystick, and not really in a position to 
get one in a hurry.

Can anyone offer any insight to my queries? Tim?

TIA

Regards,
