Re: [hatari-devel] Falcon video counter

[ Thread Index | Date Index | More Archives ]


I'll test the patch tonight ( I had in mind to test Ishar 1,2,3) ;)

I agree it may fix all of this, but that's not the good way to do it.
I have another version of the videl code that I'll try to reimplement into this version of hatari (I did it with hatari v1.6).

Anyway, if this patch also solves the Ishar games, I think it should be applied, also if I rework it later.
Maybe it was too early when I first tried to implement Videl.


PS: I spent a lot of time with Mr Splash at the Sillyventure (the guy who has coded falcamp and flaysid). We've spent some time looking what's wrong with falcamp, I continue to search with his help.
I wish I find the problem.

Thanks for this patch (remind me the command to include it in the

At Hatari repo root:

I'll have more time now that Sillyventure is over.
I'd like to retry to finish the Videl code I did 3 years ago.

I'll test this patch.

Besides fixing DLDH2, it fixes also Moonspeeder preview 2
game, Bound3 & Bound5 demos (at least they start now), and
Hextracker gets past video address counter code [1].

I added info about these to compatibility doc.

If somebody has Ishar 1, 2 or 3, it would be good if
they could test whether it works with the patch.

[1] Hextracker doesn't seem to be otherwise Falcon compatible,
I guess that testing was from time when Paulo was trying
to use Hatari in making Hextracker Falcon compatible...

Since Laurent moved all Videl register handling to falcon/videl.c
(sometime after Hatari v1.6), several programs have been broken
because that removed support for Falcon video address counter.

Attached is patch adding minimal support for that.  It fixes
"Lasers and Hommes" (DLDH2), that doesn't anymore freeze at
startup.  I assume the patch to fix most, if not all of those
regressions, but I haven't had yet time to test them.

Any comments on the patch?  Additional things that should be
taken into account / fixed (or at least add TODOs for)?

PS. Note that the patch needs to modify few items saved into
memory snapshots, so it breaks memory snapshot compatibility.
