Hi, I have been trying to run DPaint V under OS4.1 with the help of Xeron's Blitzen but I haven't been successful; every time, after having selected a screenmode, dpcpublt.library crashes, after that DPaint opens its screen but the system freezes soon after. I have tried with both DPaint 5.0 and 5.2, and with 5.2 under OS4.0 July update with the same results. As I have read of users having successfully run it under OS4, what could be the cause of the crashes?

Dosent DPaint require custom chipset??

@Tomas

Yes, but a blitter/CIA emulator like Blitzen or CIAgent should help with that.

E-UAE with JIT for PPC - improvement project might help???

I haven't tested it recently but I do remember I had to specify an 8-bit screen mode IIRC for it to work. And the palette screen I'm sure could come up as well.

@Varthall

I knew that Deluxe Paint V used the aga chipset.. maybe i am wrong..

@varthall:
dpaint requires aga. perhaps it is possible to run it under 4.0 on a classic and this is what you have heard of. i could try it at home. but obviously it doesnt help you much.

5.0 runs here on OS4.1 with fake-native screenmodes.
No GR when start or exit.

@all

The thread I was referring to is here, it's a thread about Blitzen on AmigaOne. After having re-read it I have just noticed that Hypex has managed to run DPaint IV, while V was crashing, I'll try the version IV.

@Lazi
Nice, you are using Blitzen aren't you? What hardware are you running it on?

At least demo version of DPaint V (5.0 b9) works. (Well, gadgets in a file requester has black text with black background so you have to click a button to see what it does.) I just tested and was surprised to see it works. I don't have any fake-native modes but there's PAL modes listed in screenmode requester. (DPaint's requester showed one mode for me.) You don't need Blitzen or anything. It works out of the box. (AOS4.1)

Try without Blitzen. And make sure stack size is big enough.

(Edit)
I got DPaint IV working also blacklisting it in Compatibility prefs and raising stack to 2000000 (2 million). It works only partially without Blitzen but it works better with Blitzen.

Ok, so not that bright than it looked for me.
The machine which runs DP V as I told in my last post is a standard mikroA1.
Blitzen is used, but not sure that is needed because DP V has some cpu blitting code as the dpcpublt.library suggests it.
DP IV is working too, but makes a gr at start and cannot paste brushes even with blitzen.

But...
meanwhile I tested it on a PegII (OS4.1 too with latest public fixes), but it fails to even start.
It doesn't matter if raising stack or blacklisting for jit.

So, I don't know. It needs a bit of time to test it further which I don't have currently...

Let's see other's experiences too!

@Varthall

DPaint was very good at its time, it is no good for RTG graphics, in which case I use Personal Paint (PPaint) which is similar to DPaint but works on RTG screenmodes.

You can get PPaint with Amiga Forever (Value edition or higher).

Does PPaint have animation? Does it have the light table and Move Requester to move brushes in X, Y and Z planes? I've never seen PPaint as a replacement for DPaint, DPaint was in a league of its own!

PPaint does have animation. I agree that it's not as good as DPaint in some respects though.

@pjhutch

You can download PPaint for free from Aminet as well. I'd provide a link but Aminet seems to be having some database problems ATM.

PPaint has animation? Does that mean its as intuitive and user friendly? I remember going to Disny World in Florida and having a tutorial on how to draw Pluto and then coming home and finishing it myself on Deluxe Paint using pretty much the same techniques as the Disney technology circa 2000!

Yes, but timing does not work under OS4.x so it runs too fast.

Animbrushes are better in Dpaint.

Ok, some progress made. I have tried the same DPaint V demo you used, stack set to 10.000.000 and no Blitzen, and I have discovered that it makes a yellow unrecoverable "recoverable error" if the mouse pointer is in the main empty black part of the screen. Apart for a harmless crash at the beginning which can be skipped, if I position the mouse pointer on the WB in the far right part of the screen, and press "I" (Ignore in Grim Reaper) to continue, DPaint works as it should, and I can move the pointer over the icons on the right and navigate through the menus at the top. As soon as I leave those two zones and the pointer changes into a brush, I get the freeze.

I have tried to add "SOFTSPRITE=yes" in the Radeon driver, but it makes no change; btw the option isn't available anymore since 4.1, so I believe it's not operative anymore.

I wonder if it might depend on the type of graphic card used, or if it depends whetever you're using a PS/2 or USB mouse.

Don't know about DPaint V, but DPaint IV runs here fine when I enable the "Planar screens on RTG" option in GUI Prefs (which makes OS4 emulate planar screens on RTG, as its name suggests, so programs which rely on planar modes will work.

Thats it! That was the difference on my two machines. After enabled that option on the Peg, DP V works correctly!

I just tested it here again on my OS4.1 setup. Ran DPaintIV. Selected a Radeon RTG 8-bit mode. It loaded fine, no crashes. But said it couldn't open a 256 screen as it was out of memory! I had over 40MB free video ram. And 2MB chip SetPatched. Tried to go back to WB, it's not there! DPaint had closed my Workbench screen! I didn't know we could still do that!

I decided to test an anim. It loads okay, the screen mode DPaint loads seems to work, though doesn't fit my screen. But the anim doesn't animate. All I get are flashes. I remember this. I can open up the anim panel drag the slider across and see all the frames, but playing doesn't work. So close.

I then checked my GUI settings. Hey, I don't have planar on RTG screens set! I then tested with planar setting. DPaint crashed! Then froze me. I then tried DPAintV with and without planar. Crash, yellow alert, freeze. But I didn't change the stack. And the Player is just as good, OS4 seems to think it's CLI only. (An idea for yellow and red alerts: make them look like StarTrekTNG ones. )
