Great to hear you getting on well with the msx @rubber_jonnie

@mrbombermillzy it turns out that it is analog, but when reading the stick, all I get are values from the 8 corners and trigger.
Wondering if there is a way of reading the analog values?
Not having ever had an MSX, or indeed knowing how MSX BASIC handles the joystick input, I would hazard a guess that the BASIC read command you are using actually reads the POTX/Y and if below or = 127, it's off if >127 it's on. (I'm also guessing that it has an 8-bit ADC in there).
Don't know if there's another way of reading the joystick from BASIC? :shrug:

It really is a very nice machine :)

I honestly don't know enough at present, as other than the STICK() and STRIG() commands, I am unfamiliar with the inner workings of MSX Basic. I need to dig out a manual, see what the options are.

Had a quick look for you :)
It seems that an analog stick on an MSX is not a very commonly supported thing, so try the BASIC commands Pad(17) and Pad(18) for joystick port 1 and Pad(17) and Pad(18) for port 2 to get paddle values (offset x/y -128 to +127). This should work.
If not, you may have to get dirty in that old Z80 ASM code.

Oooh thanks, I'll try that when I get the joystick reassembled.

Very impressed with the build quality, no wonder they were expensive.

Hmm, didn't work, I will have another try though. Still works fin digitally, though super mushy!
Has cleaned up very nicely with one of the auto interior wipes though :) Only thing I can't do much about is the button colour, but that's ok.

What did reading the pad values give you? (I take it you read the values into a variable, like eg: 'x=Pad(17)' or whatever and then displayed x value?)
