Joystick Port

FM-Towns joypads are fully compatible with MSX despite they do not follow the exact schematics of the MSX Tech Book because BIOS routines take into account solely the state of the bits read by register 14 and nothing else matters.

Other peripherals can be fully compatible with MSX without following the exact schematics suggested on MSX Tech Book, for example the paddles.

Seriously? A double flame bait at this point? I had you in greater regard than this.

But let's feed the troll a bit with his own food.

Yes, under a very self-serving and narrow minded concept of "fully compatible", they are. You're entitled to your own opinion, as they say.

People like to believe the weirdest things. For example, can you believe that there are those that also cherry pick info this way to prove their belief that vaccines cause autism?

We both know where do you want to arrive with this bait, right?

My reply is very simple: yes, definitely it's possible. Oduvaldo has just done something like this, and I'm sure you know about that. And he approached me to find out why his paddle wasn't being detected. He's such a nice guy, and nice team player, and now his paddles work like a charm.

As for other designs, if the creator likes to aggregate, I'm sure he will find a way to make a design that behaves exactly like the 74LS123 chip.

Otherwise, if he just likes to do things "his own way", I'm also fine with this. But he just shouldn't come to pester me if it doesn't work with my software or patches. I'm definitely not going to waste my time with someone who doesn't want to aggregate and play nice. He can waste his own time trying to fit menus for manual selection inside small MSX ROMs. I don't have he slightest pleasure of using my hobby time for something like this.

It's indeed disappointing to see that he never takes in account all the MSX history, which has its origin in computers released before, what concerns the joystick port. This part is absolutely amazing : " In addition, even before the appearance of MSX, Sharp's X1 (1982), Matsushita Tsushin Kogyo 's JR-200, and Toshiba's Pasopia 7 (1983, using the joystick adapter JOY PAC2) can also use the MSX-spec 2-button joystick. ".

Besides, he can't mention one MSX software that will not work correctly with FM-TOWNS pads. The fact that MSX joysticks are not compatible with FM-TOWNS seems for him enough to suspect potential problems when FM-TOWNS pads are used on MSX.

I must also say that we don't talk about a FM-TOWNS wiki, but a MSX wiki. It's not our role to prevent FM-TOWNS players that MSX joysticks are not compatible with FM-TOWNS software.

Last word: all the comments about 'protecting the sales of an adapter' are pure speculation. Maybe a form of jealousy?

I've provided objective information that can be proven true upon the technical analysis of both the circuits and the BIOS routines involved. Hence is a fact.

That's the exact point. The Technical Data Books provide guidance, but are far from being the ultimate rule for everything MSX.

Sure! That's why I am ignoring all impoliteness and off topics and restricting myself to the technical aspects.

If that was a try of an insult, it has fallen short, as obviously I know what open collector means and its uses.

Unless you stop hiding yourself behind loose statements and come up with a complete argument about what you're trying to prove with the open collector term, it's only possible assume that you have no damn clue about what you're talking about.

Because, after all the false accusations and personal attacks were proved to be wrong and just misunderstandings or paranoia, some people still come back here to pester every time MSX-HID is mentioned.

And such people failed to answer this simples question: "What exactly do you want now?".

Without that answer the two only possible explanation is either (1) hidden intentions, or (2) pure trolling. Which one is your case then?

At least I quote something official. You cannot even construct a full argument and keep hiding yourself into loose statements that you don't connect into a line of thought. It's just "everyone should bow to my personal opinion" and nothing else. I can't possibly agree with that, sorry.
