Origin of the uaegfx monitor file

[guest11527]

Does anyone have more information on the origin of the uaegfx monitor driver, i.e. the one that allows emulated graphics cards to be used with xxUAE? My first thought was that this should have been distributed originally with P96, but as it seems, it is not. It does not seem to be part of its internal sources, and hence must have seen in some other way the light of the day.  The problem seems to be that there is apparently a slight interface change in the latest releases of P96 that might have broken something in uaegfx, though I would prefer to understand the problem a bit better.

It is part of UAE, is it not?

I am only on ipad here, but guessing this:

Did you mean the "old" UAECALL-Interface?

I don't know, likely not. I'm wondering who might have information and/or sources for the uaegfx.monitor file I need to put into DEVS:Monitors to be able to use the emulated uaegfx card of UAE for RTG screens in UAE. I thought it might be part of the P96 source tree, but it isn't. Somebody else must have implemented this, but I don't know who and whom to ask.

Uhm, isn't that just the regular Picasso96 monitor file renamed?

You should ask Toni Wilen, I believe he was one of the authors.
He is currently reachable on the EAB Amiga forum, where he is very active.
He moderates the WinUAE section over there

The file in devs : monitors is allways the same, it is a "startup"-code for the file in argument BOARDTYPE=xxxx.card .
The "card"-files can be found in den libs : picasso96 / ...

Did you search for the source for the uaegfx.card driver?

Yes, I know.... I wanted to put things simple. Yes, I'm really looking for the uaegfx.card sources. I wrote a mail to Tony, awaiting response.

Otherwise you know where to find me.
